Greptile Overview

Greptile Summary

This PR consolidates three bug fixes and documentation updates into version 0.5.76.

Key changes:

• PostHog proxy migration: Moved session recording proxy from Next.js rewrites to middleware for large payload support, resolving payload size limitations
• React hooks fix: Replaced direct icon function calls with createElement() to prevent "rendered fewer hooks than expected" errors in OAuth credential components
• Documentation cleanup: Removed troubleshooting section from README

The PostHog change is the most impactful—moving the /ingest/ proxy from next.config.ts rewrites to the middleware proxy() function allows proper handling of large session recording payloads. The implementation correctly distinguishes between static assets (us-assets.i.posthog.com) and API endpoints (us.i.posthog.com), and properly forwards request headers with the updated host header.

The React hooks fix addresses a runtime error where icon components were being called as functions instead of being properly rendered as React components. Using createElement() ensures React's hooks are called consistently.

Confidence Score: 5/5

• Safe to merge - well-tested bug fixes with no risky changes
• All changes are straightforward bug fixes addressing known issues. The PostHog proxy migration is a clean refactor that moves logic without changing behavior, and the React hooks fix follows React best practices by using createElement.
• No files require special attention
