What's changed

Added actionable suggestions to /context command — identifies context-heavy tools, memory bloat, and capacity warnings with specific optimization tips
Added autoMemoryDirectory setting to configure a custom directory for auto-memory storage
Fixed memory leak where streaming API response buffers were not released when the generator was terminated early, causing unbounded RSS growth on the Node.js/npm code path
Fixed managed policy ask rules being bypassed by user allow rules or skill allowed-tools
Fixed full model IDs (e.g., claude-opus-4-5) being silently ignored in agent frontmatter model: field and --agents JSON config — agents now accept the same model values as --model
Fixed MCP OAuth authentication hanging when the callback port is already in use
Fixed MCP OAuth refresh never prompting for re-auth after the refresh token expires, for OAuth servers that return errors with HTTP 200 (e.g. Slack)
Fixed voice mode silently failing on the macOS native binary for users whose terminal had never been granted microphone permission — the binary now includes the audio-input entitlement so macOS prompts correctly
Fixed SessionEnd hooks being killed after 1.5 s on exit regardless of hook.timeout — now configurable via CLAUDE_CODE_SESSIONEND_HOOKS_TIMEOUT_MS
Fixed /plugin install failing inside the REPL for marketplace plugins with local sources
Fixed marketplace update not syncing git submodules — plugin sources in submodules no longer break after update
Fixed unknown slash commands with arguments silently dropping input — now shows your input as a warning
Fixed Hebrew, Arabic, and other RTL text not rendering correctly in Windows Terminal, conhost, and VS Code integrated terminal
Fixed LSP servers not working on Windows due to malformed file URIs
Changed --plugin-dir so local dev copies now override installed marketplace plugins with the same name (unless that plugin is force-enabled by managed settings)
[VSCode] Fixed delete button not working for Untitled sessions
[VSCode] Improved scroll wheel responsiveness in the integrated terminal with terminal-aware acceleration
