Enhancements

Added ability to specify gopls binary path (must be absolute) and arguments in user settings. Example: {"lsp": {"gopls": {"binary": {"path": "/my/abs/path/gopls", "arguments": ["-debug=0.0.0.0:8080"] }}}}.
Added workspace configuration settings support for elixir-ls language server. Those can now be configured by setting {"lsp": {"elixir-ls": { "settings: { "your-settings-here": "here"} } } in Zed settings (#4260).
Added more path suffixes recognized as C++.
Improved C/C++ support by using user-installed clangd when available.

Added built-in tasks for Rust and Elixir files.
Added a keybinding (shift-f12) for editor::GoToImplementation.
Added support for inserting newlines (\n) and tabs (\t) in editor Regex search replacements (#7645).
Added an assistant.enabled setting to control whether the Assistant is enabled.
Added the ability to specify no base keymap to allow for a blank slate for custom keybindings.
Added a fast-switch mode to the file finder: hit p or shift-p while holding down cmd to select a file immediately (#8258, #8757).
Improved efficiency by avoiding formatting and full saving for buffers without changes (#9475).
Improved visuals of task lists inside the markdown preview.
Improved the clarity of the UI for diagnostic and search result headers.
