 ### New features
 
-* Multi-version bundled CPython support in `flet build` and `flet publish`. Pick the runtime your app ships with via the new `--python-version` flag (3.12 / 3.13 / 3.14), or let it be derived from `[project].requires-python` in your `pyproject.toml`; defaults to the latest supported stable (currently 3.14). The matching CPython-standalone build, Pyodide release (0.27.7 / 0.29.4 / 314.0.0a2), and Emscripten wheel platform tag are all resolved from a central registry. Adding a future pre-release CPython line (e.g. 3.15 beta) is a one-row append with `prerelease=True` — opt-in only via an explicit `--python-version 3.15` or `requires-python = "==3.15.*"`, never the auto-resolved default. Requires `serious_python` >= 2.0.0, now pinned in the `flet build` template. See the new [Choosing a Python version](https://flet.dev/docs/publish#choosing-a-python-version) docs section ([#6577](https://github.com/flet-dev/flet/pull/6577)) by @FeodorFitsner.

See the new [Choosing a Python version](https://flet.dev/docs/publish#choosing-a-python-version) docs section ([#6577](https://github.com/flet-dev/flet/pull/6577)) by @FeodorFitsner.
+* Add `ft.DataChannel`: dedicated byte channels for widgets that move bulk binary data (image frames, audio buffers, ML tensors) between Dart and Python, bypassing the MsgPack control protocol. The Dart side opens a channel via `FletBackend.of(context).openDataChannel()` and announces it to Python by firing a `data_channel_open` control event with `{channel_name, channel_id}`; the Python side declares `on_data_channel_open: Optional[ft.EventHandler[ft.DataChannelOpenEvent]]` and captures the channel via `self.get_data_channel(e.channel_id)`. Backed by a dedicated `PythonBridge` per channel in embedded native mode (4–7 GiB/s on M2 Pro) and by the default `ProtocolMuxedDataChannelFactory` in dev / web modes (raw-byte frames muxed over the active Flet protocol transport with a 1-byte type discriminator). Pyodide gets zero-copy outbound sends via `postMessage` Transferable ArrayBuffer. First consumer: `flet-charts` `MatplotlibChartCanvas`, migrated from `_invoke_method` PNG dispatch to a 1-byte-opcode data channel by @FeodorFitsner.
+* **In-process Python transport (`dart_bridge` FFI).** `package:flet` gains a third protocol transport alongside the UDS / TCP socket servers: it can run Flet's MsgPack protocol over an in-process `dart_bridge` byte channel via a `FletApp(channelBuilder: …)` seam (the `flet` package stays Python-independent — it doesn't depend on `serious_python` or know about `PythonBridge`; the embedder wires the channel). `serious_python` >= 3.0.0 uses this seam to embed the Python interpreter **in-process** instead of talking to it over a localhost socket, and the `flet build` template migrates from sockets to the FFI transport. On Android, where the OS may keep the process alive across a back-button quit and restart only the Dart VM, the transport rebinds to the new VM's `dart_bridge` ports on a session-restart signal (`libdart_bridge` >= 1.3.0) — the Python process and its in-memory state are preserved and the Flet session is rebuilt from `REGISTER_CLIENT` by @FeodorFitsner.
 * Add `flet clean` command that deletes the `build` directory of a Flet app — the Flutter bootstrap project, cached artifacts, and generated output — in a single step ([#6233](https://github.com/flet-dev/flet/issues/6233)) by @ndonkoHenri.
 * Add `compression_quality` to `FilePicker.pick_files()` for selecting the image compression quality used by supported platforms ([#6573](https://github.com/flet-dev/flet/pull/6573)) by @ndonkoHenri.
 
 ### Improvements
 
+* **Smaller Android apps with no native-packaging config.** `flet build apk`/`aab` consume serious_python's new Android packaging: Python extension modules load **memory-mapped directly from the APK** (no extraction to disk), and pure Python ships in stored asset zips read via `zipimport`, so the standard library is no longer duplicated per ABI. Apps no longer need `useLegacyPackaging` / `keepDebugSymbols` — the `flet build` Android template drops them; just use `minSdk 23+`. New `--android-extract-packages` flag and `[tool.flet.android].extract_packages` ship "path-hungry" packages — those that read bundled data via `__file__` / `pkg_resources` instead of `importlib.resources` — extracted to disk instead of inside the zip (most packages, including `certifi`, are zip-safe and need no entry). Requires `serious_python` with the native-mmap packaging (dart_bridge 1.4.0).
 * Pyodide is no longer pre-baked into the `flet build` template. Each `flet build web` / `flet publish` run downloads the matching `pyodide-core-<version>.tar.bz2` (plus the runtime `micropip` and `packaging` wheels) into a per-version cache at `~/.flet/pyodide/<version>/` and copies the files into the build output. Subsequent builds reuse the cache; the older `0.27.5` bundle previously shipped in the cookiecutter template is gone ([#6577](https://github.com/flet-dev/flet/pull/6577)) by @FeodorFitsner.
-* `flet --version` now lists the supported Python versions newest first, each with its matching Pyodide release and a `default` / `pre-release` annotation where applicable, instead of the single static `Pyodide: …` line. The global `flet.version.pyodide_version` export is removed (the only external consumer was the CLI version output, now updated) ([#6577](https://github.com/flet-dev/flet/pull/6577)) by @FeodorFitsner.
+* The supported Python / Pyodide / dart_bridge versions are loaded on demand from `flet-dev/python-build`'s date-keyed `manifest.json` (fetched once and cached under `~/.flet/cache`), the single source of truth shared with `serious_python` — replacing flet's hand-mirrored version table. `flet build` forwards only `SERIOUS_PYTHON_VERSION` and lets `serious_python` derive the full version / build date / dart_bridge version from its own committed snapshot. The module exposes `get_supported_python_versions()` / `get_default_python_version()` (the previous `SUPPORTED_PYTHON_VERSIONS` / `DEFAULT_PYTHON_VERSION` constants are removed) ([#6577](https://github.com/flet-dev/flet/pull/6577)) by @FeodorFitsner.
+* `flet --version` shows just the Flet and Flutter versions; the static `Pyodide: …` line and the global `flet.version.pyodide_version` export are removed (the supported Python / Pyodide set now lives in python-build's manifest, not the CLI output) ([#6577](https://github.com/flet-dev/flet/pull/6577)) by @FeodorFitsner.
+* `flet --version --json` emits a machine-readable document — Flet/Flutter versions and the Linux build dependencies — for CI to read via `jq` instead of importing Flet internals with `python -c`. (The supported Python/Pyodide table is no longer included; it comes from python-build's manifest.) The canonical Linux apt dependency list moved from `flet.utils.linux_deps` (runtime package) to `flet_cli.utils.linux_deps` (build tooling) by @FeodorFitsner.
 * `client/web/python.js` and the build template's `python.js` no longer hardcode `defaultPyodideUrl`. `patch_index.py` now injects `flet.pyodideUrl` per build (CDN URL by default, or the local `pyodide/pyodide.js` path under `--no-cdn`) so the runtime URL always tracks the resolved Pyodide release ([#6577](https://github.com/flet-dev/flet/pull/6577)) by @FeodorFitsner.
+* Stream-oriented Flet protocol transports (UDS / TCP used by `flet run` dev mode) now use length-prefixed framing instead of streaming `msgpack.Unpacker.feed`. Combined with a new 1-byte type discriminator at the head of every packet (`0x00` = MsgPack control frame, `0x01` = raw DataChannel frame), this unifies framing across all transports (sockets, WebSocket, `dart_bridge` FFI, Pyodide `postMessage`). `StreamingMsgpackDeserializer` is removed from `package:flet`; each inbound packet is one complete MsgPack value, decoded one-shot via `msgpack.deserialize(bytes)` by @FeodorFitsner.
+* Bump the bundled Flutter to **3.44.2** (from 3.41.7). The Flet client and the `flet build` template migrate to Flutter 3.44's built-in Kotlin (the Android app no longer applies the Kotlin Gradle plugin itself) and Java 17; the client's Gradle wrapper moves to 8.14 by @FeodorFitsner.
+* **Faster mobile cold start: `import flet` is now lazy.** The `flet` package previously executed its full ~270-module public API eagerly on `import flet`; it now resolves public names on first access via a module-level `__getattr__` (PEP 562), so an app loads only the modules it actually uses. On a mid-range Android device this cut `import flet` from ~2.0s to ~0.15s. The eager subsystem clusters that `Page` pulled in (auth, components/hooks, Cupertino controls) are deferred too. Type checkers, IDEs, and `from flet import *` are unaffected ([#6597](https://github.com/flet-dev/flet/pull/6597)) by @FeodorFitsner.
 
 ### Breaking changes
 
 * `flet build` and `flet publish` now bundle CPython 3.14 by default (previously 3.12, implicit via the old single-version `serious_python`). Existing apps that depend on native wheels without 3.14 binaries should pin explicitly with `--python-version 3.12` (CLI), `requires-python = ">=3.12,<3.13"` (pyproject), or `SERIOUS_PYTHON_VERSION=3.12` in the build environment ([#6577](https://github.com/flet-dev/flet/pull/6577)) by @FeodorFitsner.
-* The `flet.version.pyodide_version` module attribute and the `PYODIDE_VERSION` constant are removed. Reach for `flet_cli.utils.python_versions.SUPPORTED_PYTHON_VERSIONS` if you need the per-version Pyodide mapping programmatically ([#6577](https://github.com/flet-dev/flet/pull/6577)) by @FeodorFitsner.
+* Android builds now include only the ABIs the bundled Python supports: for Python 3.13+, `armeabi-v7a` is no longer supported nor packaged by default. An explicit `--arch armeabi-v7a` fails with a clear error unless combined with `--python-version 3.12`, which is the only Python version supporting it. The per-version ABI set is sourced from python-build's manifest (`pythons.<short>.android_abis`), not hardcoded in flet ([#6578](https://github.com/flet-dev/flet/pull/6578)) by @ndonkoHenri.
+* `flet build` / `flet publish` now **compile your app and packages to `.pyc` by default** (previously off). This removes per-launch bytecode recompilation — a significant cold-start win, especially on mobile where pure Python is imported from a stored zip (`zipimport`) and can't cache bytecode back to disk, so every module would otherwise recompile from source on each launch. The CLI flags gain `--no-compile-app` / `--no-compile-packages` (via `argparse.BooleanOptionalAction`; the existing `--compile-app` / `--compile-packages` still work), and `[tool.flet.compile].app` / `.packages` now default to `true`. Pass `--no-compile-*` or set them to `false` to restore the old behavior (faster iterative builds, or keeping `.py` source in the bundle). Compiled web builds were verified to load in Pyodide (bundled CPython and Pyodide share the same minor version). See the [compile-on-by-default](/docs/updates/breaking-changes/v0-86-0-compile-on-by-default) guide ([#6598](https://github.com/flet-dev/flet/pull/6598)) by @FeodorFitsner.
+* Flet protocol wire format on stream-oriented transports (UDS / TCP) is incompatible with pre-0.86 servers and clients. Every packet now starts with a 4-byte little-endian length prefix and a 1-byte type discriminator (`0x00` = MsgPack control frame, `0x01` = raw DataChannel frame). WebSocket / `postMessage` / `dart_bridge` transports keep native message boundaries and only gain the type byte. The Flet CLI dev server and the in-process Python runtime are upgraded in lockstep — running `flet run` with mismatched `flet` versions across CLI and runtime is no longer supported. See the [DataChannel protocol framing upgrade](/docs/updates/breaking-changes/v0-86-0-data-channel-protocol-upgrade) guide. The `MatplotlibChartCanvas` widget transports its full / diff / clear frames via a `DataChannel` rather than `_invoke_method` arguments — visually identical, but custom code that subclassed it and overrode the apply methods may need updating by @FeodorFitsner.

 ### Bug fixes
 
 * Fix `flet build` failing on Windows when a dependency is pulled in via `[tool.flet.<platform>].dev_packages` (or any local-path install): the rewritten `<pkg> @ file://<path>` URL now uses `Path.as_uri()`, producing the correct `file:///D:/...` three-slash form instead of `file://D:\...`, which pip on Windows parsed as a UNC path and aborted with `OSError: [Errno 2] No such file or directory: '\\\\D:\\a\\...'` ([#6577](https://github.com/flet-dev/flet/pull/6577)) by @FeodorFitsner.
+* Fix `flet build web --python-version 3.13` failing to match any Pyodide-built native wheel. The 3.13 row in the Python version registry was set to Pyodide platform tag `pyodide-2025.0-wasm32`, but Pyodide actually publishes 0.29 wheels under `pyemscripten_2025_0_wasm32` (the `pyodide_` → `pyemscripten_` prefix transition happened at 0.28/0.29, not at 314.0). Corrected to `pyemscripten-2025.0-wasm32` so pip's wheel selection picks up the correct tags by @FeodorFitsner.
+* `flet build` now cleans the build directory when the bundled Python version changes between builds, preventing stale compiled bytecode from the previous version crashing the app at runtime with `ImportError: bad magic number` by @FeodorFitsner.
+* Fix locating Flet controls by their user-assigned `key` in tests. `ValueKey(control.key)` was constructed as `ValueKey<Object>`, and Flutter's runtimeType-strict `ValueKey.==` never matches that against the `ValueKey<String>` the rendered widget carries — so `find.byKey(Key('foo'))` (flutter_test) and `find_by_key('foo')` (Flet tester) located 0 widgets. The `ValueKey` is now built with the value's concrete type (String → `ValueKey<String>`, int → `ValueKey<int>`, …) on both the Dart and Python sides by @FeodorFitsner.
+* Fix `flet build apk` / `flet build aab` with `--arch` packaging native libraries for *all* Android ABIs instead of only the requested ones. The requested architectures are now forwarded to Flutter as `--target-platform` (so `--split-per-abi` builds only the requested splits), unrequested ABI directories are excluded from the artifact via `packaging.jniLibs.excludes`, Android `--arch` values are validated against the bundled Python's supported ABIs, multiple `--arch` values now correctly reach `serious_python` (comma-joined), and stale artifacts from previous builds are no longer copied into the output directory ([#6567](https://github.com/flet-dev/flet/issues/6567), [#6578](https://github.com/flet-dev/flet/pull/6578)) by @ndonkoHenri.
+* Fix repeated `--arch`, `--source-packages` and `--permissions` flags in `flet build` keeping only the values of the last occurrence (`action="extend"` on each) ([#6578](https://github.com/flet-dev/flet/pull/6578)) by @ndonkoHenri.
 * Fix `flet build apk` failing at `mergeDebugNativeLibs` with `N files found with path 'lib/<abi>/libc++_shared.so'` when an app combines `serious_python_android` with another Flutter plugin that also bundles the NDK C++ runtime ([#6570](https://github.com/flet-dev/flet/issues/6570), [#6571](https://github.com/flet-dev/flet/pull/6571)) by @ndonkoHenri.
 * Specify `handler` signatures in `subscribe` and `subscribe_topic` methods of `PubSubClient` for better type checking ([#6549](https://github.com/flet-dev/flet/pull/6564)) by @Iaw4tch
 * Fix `FilePicker.pick_files()` on web for slow network shares or slow machines: pass `cancel_upload_on_window_blur=False` to prevent valid file selections from being reported as cancelled when the browser window loses focus during file picking ([#771](https://github.com/flet-dev/flet/issues/771), [#6573](https://github.com/flet-dev/flet/pull/6573)) by @ndonkoHenri.

+"""Widget-facing byte-channel API.
+
+A `DataChannel` is a dedicated bidirectional byte transport between a
+single widget's Dart side and its Python counterpart, separate from the
+Flet control protocol. Used for bulk binary data — image frames, audio
+buffers, ML tensors — that would otherwise pay MsgPack encode/decode
+overhead through the regular protocol channel.
+
+The transport implementation is chosen by the active Connection subclass:
+
+- `FletDartBridgeServer` (embedded native via `dart_bridge`): each
+  channel rides its own dedicated PythonBridge native port (4–7 GiB/s on
+  M2 Pro).
+- `FletSocketServer` / `flet_web.fastapi.FletApp` (dev mode, web with
+  Python server): bytes are muxed over the active Flet protocol
+  transport with a 1-byte type discriminator (0x01) + 4-byte channel id.
+
+Allocation lives on the Dart side. The widget's Dart code calls
+`FletBackend.of(context).openDataChannel()` in `initState`, then fires a
+`data_channel_open` control event carrying `{channel_name, channel_id}`.
+The Python widget declares `on_data_channel_open:
+Optional[ft.EventHandler[DataChannelOpenEvent]] = None` and inside the
+handler calls `self.get_data_channel(e.channel_id)` to attach.

+In-process dart_bridge transport for Flet's embedded mode.
+
+`FletDartBridgeServer` is an alternative to `FletSocketServer` that exchanges
+the same MsgPack-framed protocol over an in-process byte channel rather than a
+Unix-domain socket. The channel is provided by the `dart_bridge` built-in
+Python module, registered with CPython via `PyImport_AppendInittab` by
+`libdart_bridge` (the native artifact in `flet-dev/dart-bridge`).
+
+Activation: `flet.app.run_async` instantiates this server when
+`FLET_DART_BRIDGE_PORT` is set AND `is_embedded()` is true. The Dart-side port
+acts as the channel key in both directions:
+
+- inbound  (Dart → Python): dart_bridge invokes `__on_bytes(payload)` from C
+  under the GIL whenever the Dart side calls `bridge.send(bytes)`.
+- outbound (Python → Dart): `send_message` calls `dart_bridge.send_bytes(
+  port, packed)` which non-blockingly posts to the Dart native port.
+
+The MsgPack protocol layer is identical to `FletSocketServer`; only the byte
+transport differs.

+
+## Conclusion
+
+TBD
+
+Flet 0.86.0 fills in two pieces that declarative apps were really missing: routing and dialogs. Combined with smoother video, real-time audio, and a healthy round of bug fixes, this release moves the `@ft.component` programming model from "promising" to "production-ready for real apps".
+
+Try it in your apps and share feedback in [GitHub Discussions](https://github.com/flet-dev/flet/discussions) or on [Discord](https://discord.gg/dzWXP8SHG8).
+
+Happy Flet-ing!

+## Dedicated data channels
+
+Property updates and method calls between Python and Dart go over Flet's MsgPack-framed control protocol. That works well for widget state and small events but caps at ~1 GB/s with several allocations per frame. For widgets that need to move **bulk binary data** — image frames, audio buffers, file blobs, ML inference tensors — Flet provides **dedicated `DataChannel`s** that bypass MsgPack entirely and reach memory-bandwidth-class throughput on every supported platform.
+
+Examples of widgets that benefit:
+
+- A chart receiving a stream of bitmaps from Python (1080p RGBA at 60 fps ≈ 480 MB/s — far above what the control protocol can sustain)
+- A camera widget pushing frames Dart → Python for ML inference
+- A microphone widget streaming PCM samples to a Python DSP pipeline
+
+For sub-KB widget state, you don't need this — the regular property protocol is faster end-to-end at that size. Reach for `DataChannel` when payloads start at a few KB and especially when they stream at high rates.
+
+### How it works
+
+Allocation lives on the **Dart side**: the widget calls `FletBackend.of(context).openDataChannel()` in `initState`, then **fires a control event named `data_channel_open`** carrying `{channel_name, channel_id}`. The Python side declares an `on_data_channel_open` handler, retrieves the matching channel via `Control.get_data_channel(channel_id)`, and starts sending/receiving bytes.
+
+Transport is chosen per deployment mode automatically — dedicated `PythonBridge` per channel in embedded native (`flet build` for desktop/mobile), raw-byte frames muxed over `postMessage` with Transferable ArrayBuffer in Pyodide, muxed over the protocol socket in `flet run` dev mode, muxed over WebSocket with a Python server. **Widget code is identical across all modes.**
+
+### Python-side API
+
+```python
+from typing import Callable, Optional
+
+import flet as ft
+
+
+@ft.control("MyImageChart")
+class MyImageChart(ft.LayoutControl):
+    on_data_channel_open: Optional[ft.EventHandler[ft.DataChannelOpenEvent]] = None
+
+    def init(self) -> None:
+        # `init` is the @ft.control post-construct hook (runs before `did_mount`).
+        # Wire up the channel-capture handler here.
+        self._frames: Optional[ft.DataChannel] = None
+        if self.on_data_channel_open is None:
+            self.on_data_channel_open = self._capture_channel
+
+    def _capture_channel(self, e: ft.DataChannelOpenEvent) -> None:
+        # `e.channel_name` is the label the Dart side put in the event
+        # payload — dispatch on it when a widget opens multiple channels.
+        # Single-channel widgets can ignore it.
+        self._frames = self.get_data_channel(e.channel_id)
+        # Optional: subscribe to bytes flowing Dart → Python.
+        self._frames.on_bytes(self._on_frame_from_dart)
+
+    def push_frame(self, rgba_bytes: bytes) -> None:
+        """Python → Dart — fire-and-forget byte send."""
+        if self._frames is not None:
+            self._frames.send(rgba_bytes)
+
+    def _on_frame_from_dart(self, payload: bytes) -> None:
+        # Called from the transport's delivery thread (under the GIL in
+        # embedded native mode). Push to a `queue.Queue` and let a worker
+        # drain — don't do heavy CPU work here, it'll starve the transport.
+        ...
+```
+
+`ft.DataChannel` is an abstract class — instances come back from `Control.get_data_channel(channel_id)`. Its surface:
+
+- `send(payload: bytes)` — Python → Dart, fire-and-forget
+- `on_bytes(callback: Callable[[bytes], None] | None)` — register a handler for bytes pushed from Dart; pass `None` to clear
+- `close()` — release the channel (idempotent; the framework auto-closes on control unmount, you rarely need to call it explicitly)
+
+The `ft.DataChannelOpenEvent` fields are `channel_name: str` and `channel_id: int`. The field is `channel_name`, not `name`, because `name` is reserved on the base `Event` class for the event's own name (`"data_channel_open"`).
+
+### Dart-side API
+
+```dart
+import 'package:flet/flet.dart';
+
+class MyImageChartState extends State<MyImageChartWidget> {
+  late final DataChannel _frames;
+  StreamSubscription<Uint8List>? _sub;
+
+  @override
+  void didChangeDependencies() {
+    super.didChangeDependencies();
+    if (_sub != null) return;  // initialise lazily, once
+    _frames = FletBackend.of(context).openDataChannel();
+    _sub = _frames.messages.listen(_onFrameFromPython);
+    // Tell Python about the channel via a regular control event.
+    widget.control.triggerEvent("data_channel_open", {
+      "channel_name": "frames",
+      "channel_id": _frames.id,
+    });
+  }
+
+  void _onFrameFromPython(Uint8List bytes) {
+    // hand to a Texture, dart:ui.Image.fromPixels, etc.
+  }
+
+  void _pushFrameToPython(Uint8List bytes) {
+    _frames.send(bytes);
+  }
+
+  @override
+  void dispose() {
+    _sub?.cancel();
+    _frames.close();
+    super.dispose();
+  }
+}
+```
+
+`DataChannel` Dart-side surface:
+
+- `int get id` — the channel identifier that goes into the `data_channel_open` event payload
+- `Stream<Uint8List> get messages` — bytes pushed from Python
+- `bool send(Uint8List bytes)` — Dart → Python, fire-and-forget
+- `void close()` — release the channel (idempotent)
+
+**Allocate the channel in `didChangeDependencies`, not `initState`** — `FletBackend.of(context)` needs an active `BuildContext` and that's the first lifecycle hook where it's safely available.
+
+Neither side imports `serious_python` or `dart_bridge`. The DataChannel API surface lives entirely in `package:flet` / `flet`, so your extension's dependencies stay the same.
+
+### Multiple channels per widget
+
+A control can open as many channels as it needs — each `openDataChannel()` call mints a unique id. Disambiguate them by `channel_name` in the event:
+
+```dart
+// Dart — open two channels, label each
+_frames = FletBackend.of(context).openDataChannel();
+_audio  = FletBackend.of(context).openDataChannel();
+widget.control.triggerEvent("data_channel_open", {
+  "channel_name": "frames",
+  "channel_id": _frames.id,
+});
+widget.control.triggerEvent("data_channel_open", {
+  "channel_name": "audio",
+  "channel_id": _audio.id,
+});
+```
+
+```python
+# Python — dispatch on channel_name
+def _on_data_channel_open(self, e: ft.DataChannelOpenEvent) -> None:

+            self._audio = self.get_data_channel(e.channel_id)
+```
+
+### Threading + backpressure
+
+The `on_bytes` handler runs **synchronously under the GIL** on whatever OS thread the transport delivered from. For anything CPU-heavy (PNG decode, ML inference) push the payload onto a `queue.Queue` or `asyncio.Queue` and let a worker drain — blocking the delivery thread will starve the transport.
+
+The receiving side's queue is **unbounded by default**. If a producer outpaces the consumer (camera frames into a slow decoder, matplotlib rotation into Flutter paint), memory grows. For media-streaming widgets, implement backpressure or a drop-old policy on the producer side. A reference example is [`MatplotlibChartCanvas`](https://github.com/flet-dev/flet/blob/main/sdk/python/packages/flet-charts/src/flet_charts/matplotlib_chart_canvas.py) — it uses a 1-byte ack frame from Dart so the producer waits per-frame, mirroring matplotlib WebAgg's `waiting` flag pattern.

+:::
+
+## Summary
+
+`flet build` now **compile your app and the installed
+packages to `.pyc` by default** (via `python -m compileall -b`, with the original
+`.py` files removed from the bundle). Previously compilation was off unless you
+opted in with `--compile-app` / `--compile-packages` or
+`[tool.flet.compile]` in `pyproject.toml`.
+
+Shipping bytecode removes per-launch recompilation. The win is largest on
+**mobile**, where pure Python is imported from a stored, in-place zip
+(`zipimport`) that cannot cache bytecode back to disk — so without precompiled
+`.pyc`, every module is recompiled from source on **every** cold start. On a
+mid-range Android device this costs roughly 1–2 seconds of startup, scaling with
+the number of modules imported.
+
+## Background
+
+Compilation has always been available behind the `--compile-app` /
+`--compile-packages` flags; it just defaulted off. With the move to in-place
+`zipimport` packaging on Android, leaving it off meant a recurring cold-start tax
+on every launch, so the default was flipped on.
+
+Compiled web builds were verified to load correctly in Pyodide: the standalone
+CPython used to compile and the Pyodide runtime share the same minor version
+(e.g. 3.14), and CPython keeps the `.pyc` magic number stable across patch
+releases of a minor version, so the bytecode is accepted.
+
+## Migration guide
+
+Most apps need no changes — builds simply start faster.
+
+If you relied on uncompiled builds (to keep `.py` source in the bundle for
+debugging, to let a build complete despite syntax errors, or to speed up
+iterative builds), opt out explicitly.
+
+### Opt out via the CLI flag
+
+The flags are now `argparse.BooleanOptionalAction`, so each gets a `--no-` form
+(the original `--compile-app` / `--compile-packages` still work):
+
+```bash
+flet build apk --no-compile-app --no-compile-packages
+```
+
+### Opt out in `pyproject.toml`
+
+```toml
+[tool.flet.compile]
+app = false
+packages = false
+```
+
+Per-platform overrides also work, e.g. `[tool.flet.android.compile]`. The
+resolution order is CLI flag → `[tool.flet.<platform>.compile]` →
+`[tool.flet.compile]` → default (`true`).

+# Flet protocol framing upgraded for DataChannel support
+
+:::note
+This guide is accurate as of Flet 0.86.0. Later releases might add new APIs or
+additional migration paths.
+
+The [breaking changes and deprecations index](.) lists the guides created for each release.
+:::
+
+## Summary
+
+Flet 0.86.0 introduces dedicated **data channels** for widgets that need to
+move bulk binary data (image frames, audio buffers, ML tensors) between Dart
+and Python without going through the MsgPack control protocol.
+
+Enabling this required a one-time upgrade of the Flet protocol's wire format:
+
+- **Stream-oriented transports** (`flet run` dev mode over UDS / TCP) now use
+  **4-byte little-endian length-prefixed framing**. The previous streaming
+  `msgpack.Unpacker.feed` decode is gone.
+- **Every transport** (sockets, WebSocket, `dart_bridge` FFI, Pyodide
+  `postMessage`) now puts a **1-byte type discriminator** at the head of each
+  packet:
+  - `0x00` — MsgPack-encoded Flet control frame (widget state, events) — same
+    contents as before, just with a type byte in front.
+  - `0x01` — raw DataChannel frame (`[channel_id:u32 LE][payload]`).
+
+The new format is **not backwards-compatible**: a Flet 0.85 client cannot talk
+to a Flet 0.86 server, and vice versa. The `flet-cli` dev server and the
+in-process Python runtime were upgraded together in this release.
+
+## Background
+
+Flet's previous wire format on UDS / TCP relied on `msgpack.Unpacker.feed` to
+re-assemble messages from arbitrary byte-stream chunks. That works for
+MsgPack-only traffic but doesn't compose with a second logical stream of raw
+bytes — you can't tell a partial MsgPack value from the start of a raw frame
+without an out-of-band marker.
+
+Adding the 1-byte type byte + 4-byte length prefix solves this in the smallest
+possible way:
+
+- Receivers read `[length][type][...]`, fan out by type byte, no streaming
+  decoder state to maintain.
+- Message-oriented transports (WebSocket, `postMessage`, `dart_bridge`) drop
+  the length prefix since each message is already one packet; they keep the
+  type byte.
+- Per-frame overhead is 5 bytes (message-oriented) or 9 bytes (stream-oriented)
+  — under 1% at any payload size that motivates a data channel.
+
+## Migration guide
+
+### Most users — nothing to change
+
+If you only use `flet build` artifacts or run `flet run` with the matching
+`flet` package version (the default install pulls both at once), there's
+nothing to do. The CLI and the runtime are version-locked.
+
+### Users running `flet-cli` and the `flet` Python package from different installs
+
+Make sure both come from the same release. The common gotcha is a global
+`flet` install plus a project-local `flet` in `.venv` at different versions
+— upgrade or pin both to ≥ `0.86.0` (or both to ≤ `0.85.x`).
+
+A version mismatch will surface as a connection failure during `flet run`
+with a parse error in the dev-server log.
+
+### Users with custom backends or sidecars speaking the Flet protocol
+
+The wire format changed. Update your encoder/decoder:
+
+- **Inbound on a stream transport** (UDS / TCP): read 4 bytes (length, u32 LE),
+  read that many bytes, the first byte is the type discriminator, the rest is
+  the payload.
+- **Inbound on a message transport** (WebSocket, `postMessage`): each
+  message's first byte is the type discriminator, the rest is the payload.
+- **Outbound**: same shape, mirrored.
+
+Treat `0x01` (raw DataChannel) frames as opaque if you don't use data channels
+— forward them along or drop them, never feed them to your MsgPack decoder.
+
+### Code that depended on `StreamingMsgpackDeserializer`
+
+The Dart-side class `package:flet/src/transport/streaming_msgpack_deserializer.dart`
+is removed. There are no public consumers — it was an internal helper for
+stream-transport framing that's no longer needed now that every packet is
+length-delimited. If you imported it (you shouldn't have), decode each inbound
+buffer with one-shot `msgpack.deserialize(bytes)` instead.
+
+### Custom widgets that override `MatplotlibChartCanvas`
+
+`MatplotlibChartCanvas` now transports its `apply_full` / `apply_diff` /
+`clear` frames through a [DataChannel] rather than `_invoke_method` arguments.
+The Python-facing method signatures are unchanged (`apply_full(image_bytes:
+bytes)`, etc.), and they remain the documented API. But if you subclassed the
+canvas and overrode the Dart-side `_invokeMethod` handler, that override no
+longer fires — the Dart side now consumes a 1-byte opcode + PNG payload from
+the channel directly.

+# Default bundled Python version is now 3.14

+:::
+
+## Summary
+
+Flet 0.86.0 introduces multi-version bundled CPython support to `flet build`
+and `flet publish`. The bundled Python interpreter is now selected per build
+(see [Choosing a Python version](/docs/publish#choosing-a-python-version)) and
+the **default is the latest supported stable** — currently CPython 3.14.
+Earlier Flet releases implicitly bundled CPython 3.12 via the single-version
+`serious_python` 1.x.
+
+Apps that depend on Python packages whose pre-built wheels aren't yet
+available for 3.14 (typically packages with C/Rust extensions that haven't
+caught up to the new ABI) need to pin a previous Python version.
+
+## Background
+
+Multi-version Python support landed in
+[#6577](https://github.com/flet-dev/flet/pull/6577) and is tracked by the
+central registry in
+[`flet_cli/utils/python_versions.py`](https://github.com/flet-dev/flet/blob/main/sdk/python/packages/flet-cli/src/flet_cli/utils/python_versions.py).
+The supported short versions are `3.12`, `3.13`, and `3.14` (each pinned to a
+specific CPython patch + Pyodide release on the registry side).
+
+The default flips to the latest stable so new projects get the most recent
+Python by default. Existing projects without a pin start picking it up too on
+their next build.
+
+## Migration guide
+
+You can pin a different Python version in three equivalent ways. Use whichever
+fits your project layout.
+
+### Pin in `pyproject.toml` (recommended)
+
+Add or update `[project].requires-python`:
+
+```toml
+[project]
+requires-python = ">=3.12,<3.13"
+```
+
+`flet build` parses the specifier and picks the **highest supported short
+version** that satisfies it. So `>=3.12,<3.13` resolves to 3.12,
+`>=3.13,<3.14` resolves to 3.13, and `>=3.14` resolves to 3.14 (the default).
+
+### Pin via the CLI flag
+
+Pass `--python-version` on every invocation:
+
+```bash
+flet build apk --python-version 3.12
+flet publish --python-version 3.12
+```
+
+The CLI flag overrides anything in `pyproject.toml`.
+
+### Pin via environment variable
+
+Export `SERIOUS_PYTHON_VERSION` in the shell that runs `flet build`:
+
+```bash
+export SERIOUS_PYTHON_VERSION=3.12
+flet build apk
+```
+
+Useful in CI pipelines where you don't want to thread the flag through every
+job.

+multi-version bundled Python support — the bundled release depends on which
+Python version your app pins, not a global default.
+
+## Background
+
+Earlier Flet releases used a single Pyodide pin in `flet.version` to drive the
+`flet --version` output and let tooling read which Pyodide release `flet build
+web` would bundle. With
+[multi-version Python support](/docs/publish#choosing-a-python-version) the
+mapping is now Python-version-aware (`3.12 → 0.27.7`, `3.13 → 0.29.4`,
+`3.14 → 314.0.0`). It is loaded on demand from
+[python-build's date-keyed `manifest.json`](https://github.com/flet-dev/python-build)
+— the single source of truth shared with serious_python — via
+[`flet_cli/utils/python_versions.py`](https://github.com/flet-dev/flet/blob/main/sdk/python/packages/flet-cli/src/flet_cli/utils/python_versions.py),
+so it is no longer hand-maintained.
+
+## Migration guide
+
+If you imported the constant somewhere — typically from `flet.version` —
+switch to looking the release up from the new registry.
+
+Code before migration:
+
+```python
+import flet.version
+
+print(f"Bundled Pyodide: {flet.version.pyodide_version}")
+```
+
+Code after migration:
+
+```python
+from flet_cli.utils.python_versions import get_supported_python_versions
+
+for release in get_supported_python_versions():
+    print(f"  {release.short} → Pyodide {release.pyodide}")
+```
+
+If you only need the version that `flet build` is about to bundle, resolve
+the Python release the same way the CLI does:
+
+```python
+from flet_cli.utils.python_versions import (
+    get_default_python_version,
+    get_release,
+)
+
+release = get_release(get_default_python_version())
+print(f"Default Pyodide: {release.pyodide}")
+```
