0.11.1

Patch-level changes

0.11.0

Major changes

Build Prefix as a shared runtime DLL with a matching import library, and link both the interpreter executable and compiled extensions against that shared runtime.

Refine extension namespace exposure so module-qualified operators require a dedicated module-restriction flag rather than relying on PREFIX_EXTENSION_ASMODULE alone.

Minor changes

Add the APPEND built-in for appending a single element to a one-dimensional tensor.

Allow unqualified resolution of module-restricted extension operators within modules that extended them, and preserve those extension namespaces when such modules are imported through an alias.

Patches

Update the bundled networking, win32, gui, and image extensions to use the new module-restriction semantics.

Update image helpers so SHOW loads its Windows dependency explicitly and INVERT preserves the alpha channel.

Fix floating-point rendering so infinities stringify correctly.

0.10.0

Major changes

Add the first-class BOOL type with the TRUE and FALSE literals, and change the language's Boolean model to use BOOL rather than integer sentinel values.

Change built-in and standard-library APIs that previously returned INT sentinel values to return BOOL instead, including logical, comparison, type-checking, import, filesystem, console, freeze, and deletion operators, along with helpers such as prime.IS_PRIME, prime.IS_MERSENNE_PRIME, and image.SHOW.

Minor changes

Bind SELF when calling FUNC values stored in MAP objects, preserving aliasing when the map is accessed through a pointer.

Update pointer semantics so transformed built-in results write back through pointer operands, and pointer arguments to user-defined functions bind as aliases.

Patches

Allow BOOL values in conversions, truthiness, tensor elements, serialization, deserialization, printing, and default FUNC returns.

Fix image save operators to report runtime failures correctly.

Refactor the documentation site to use shared CSS and Markdown rendering, and generate the specification table of contents automatically.
