Beta 2

Fix that GitHub Copilot chat was not usable in the new chat tab.
Other minor fixes.

What’s New

Adds a new chat tab to replace the old one. The old chat tab will not be automatically converted to the new one, so you need to manually start a new chat.

The new things are:
- New UI
  - The responses will make use of the full width of the window. The text contents will still have a max width so they are more readable when the window is too wide.
  - Reimplemented the pin-to-bottom behavior.
- New context picker that allows you to better control the context of the chat.
  
  You can add context by clicking the + button and remove context by clicking the x button. You can still use @ to add a scope to the context, we will improve this part in the later betas.
- Updated prompt format to better utilize prompt caching from OpenAI and Claude.
- Apply button on the code block to apply the suggestions to the target file or the current file. The chat will also prompt the chat models to indicate the target file of a code block. (The implementation is still in progress, so it may not work as expected and may take some time to complete.)
  
  In this example, clicking the apply button will generate the new file content with the suggestion for the file Contents.swift. The new content will be presented in the modification window.
- You can send multiple message at the same time without waiting for the response.
- The custom command will behave differently now. The extra system prompt will now be injected into the context as a topic. Topics will be put into the system prompt.

0.33.8

Fix Codeium chat for enterprise users.
Fix that the widget location is not updated when switching to another Xcode window in another space.

Remove the last line of a suggestion if it’s closing parenthesis and is identical to the next line.
Fix that a detached chat panel will be moved to the active space when switching space.
Fix that a detached chat panel may be moved to the back unintentionally.
Add a toggle to detect idle tabs per tab bar.
Fix that the app may crash when it’s installed in a folder that is not Applications. But installing in other folders is still not supported. If you want a workaround, please try #562.

0.33.6

Fix that the Codeium language server could run even though it’s not used.

0.33.5

Support Codeium indexing
Support a proof-of-concept version of GitHub Copilot chat. Please note that this feature is still in an early stage of development and may change in the future. To use it, you have to turn on “Pretend IDE to be VSCode” in the GitHub Copilot settings and change the chat model to “GitHub Copilot (poc)”.

This implementation uses the language server to access the GitHub Copilot chat, so it should be much more legal than copilot-gpt4-service. The only(?) not-so-legal thing is that we need to use VSCode as the IDE name. Custom system prompt and temperature will not work for GitHub Copilot chat. Scopes will work. The built-in RAG of GitHub Copilot chat may not work properly.
Bump Copilot.vim to 1.37.0 and fixes.
Add a “Utility chat model” picker in the chat settings. This model will be used when it need to use LLM as a tool.
Prevent repeated parsing of markdown content in chat panel on scroll.
Add new models for Google Gemini and Claude.
Move appcast.xml to https://copilotforxcode.intii.com/appcast.xml

0.33.5

beta

Beta 2

Fix that the app will crash when GitHub Copilot was asked to generate non-stream response. But since we can’t change the system prompt, we can’t use it to do anything other than chat. I have added a “Utility chat model” picker in the chat settings. If you need to use scopes that require LLMs to perform certain tasks (for example the project scope), you’d better set it up. Fixes #552
