Crush v0.88.1 Changelog

This update is a big maintenance release focused on making the app more reliable, especially for people using it in advanced setups like client-server mode (where the app runs on one computer and you interact with it from another). If you use this tool for heavy coding tasks, this version fixes a lot of annoying bugs that used to slow you down or cause crashes.

What's new

• Smarter background tool connections: The app no longer keeps a "callback port" (a communication channel for external tools) open permanently. This frees up system resources and makes connections cleaner.

Improvements

• Cleaner interface: The color used to show when something "needs auth" (needs you to log in) has been updated to "tang," and the theme naming system was cleaned up behind the scenes.
• Better money display: If the server reports your usage costs in US Dollars, the app will now hide the internal "hypercredits" number to avoid confusing you.
• Smoother code updates: The way the app rebuilds its AI models in the background was rerouted through a single helper tool, making it more organized.
• Clearer guides: The documentation now clearly states that crushrc is the main config file (the file where you save your app settings), instead of an older format called crush.json. It also added missing instructions for adding OAuth (secure login) to external tools.

Fixes

• Typing lag over networks: Fixed a bug where typing was super laggy if you were using the app over a network connection (TCP in client/server mode).
• Crashing sessions: Fixed an issue where running multiple sessions at the same time would cause them to accidentally kill each other.
• Crashing code helpers: Fixed a problem where the app would crash if the language server (the tool that checks your code as you type) tried to show a progress bar.
• Lost error messages: Fixed a bug where error messages from the back-end (the server doing the heavy lifting) weren't showing up on your screen.
• Broken caches: Fixed issues where the app's temporary memory (cache) would break if it couldn't save new data, or if it tried to rewrite the memory while swapping it out. Now it just swaps the old memory for the new memory safely.
• Permission pop-ups: Fixed the permission guard (the system that asks if you're sure you want to do something) so it waits longer during natural typing pauses, instead of cutting you off.
• Summarize command: Added a missing shortcut so you can easily ask the app to summarize a chat.
• External tool timeouts: Lowered the default wait time (timeout) for MCP (Model Context Protocol) tools to respond, so the app doesn't hang around waiting forever if a tool gets stuck.
• Network login fixes: Fixed authentication (login) for external tools when using the app in client-server mode.
• Old server cleanup: Fixed an issue where old, idle servers that predated a recent shutdown feature would stick around and become stale.
• Windows cleanup: Fixed a bug where the app would try to clean up temporary files on Windows before the test database was finished using them.
• Test stability: Fixed a few behind-the-scenes bugs that caused the app's automated tests to randomly fail (flaky tests) or leave database connections open.
