 ** Main branch change
+
+** 1.77
+- Chore: Remove eval_elisp mode and symbol restrictions
+- Chore: Treat documentation changes as non-code changes
 - Breaking: Remove =ai-code-mcp-editor-tools.el= and merge its remaining MCP tools into the core server and debug modules
   - =editor_state= and =visible_buffers= are now built-in MCP tools in =ai-code-mcp-server.el=
   - =eval_elisp= now lives in =ai-code-mcp-debug-tools.el= and is gated by =ai-code-mcp-debug-tools-enable-eval-elisp=
   - Remove the legacy =messages_tail= tool in favor of =get_recent_messages=
   - Remove the old =ai-code-mcp-editor-tools-enabled= and =ai-code-mcp-editor-tools-allow-effect-eval= settings
   - Move the dedicated editor-tools tests into the server/debug MCP test files
   - Update MCP docs and release notes to match the new tool layout
+- Feat: Add Kilo backend support (Opencode fork)
+- Feat: Support Org TODO headlines in implement-todo
 
 ** 1.74
 - Fix: Guard eat/ghostel process filters against deleted buffers on exit and add regression tests

-- =eval_elisp=: evaluate a single Emacs Lisp form in a chosen buffer context when explicitly enabled
+- =eval_elisp=: evaluate arbitrary Emacs Lisp with possible side effects in a chosen buffer context when explicitly enabled (no restrictions once enabled)
 
 The old =ai-code-mcp-editor-tools.el= module has been removed. Its live-editor read tools are now built in, while =eval_elisp= remains an explicit opt-in.

It takes =code= (a single top-level form), optional =buffer_name= or =file_path= for evaluation context, optional =capture_messages= to collect new =*Messages*= output, optional =include_backtrace= to include a backtrace on failure, and optional =timeout_ms=. This is useful for letting the AI apply fixes by evaluating modified function definitions directly.
