VSCode Extension 0.890.2 Release Notes

This stable release rolls up everything since the last stable (v0.859.7), promoting the v0.890.1 pre-release to stable.

Chat zoom: zoom the chat view in and out to your preference.
Timestamps: optional per-message timestamps, with a consolidated User Experience settings section.
/threads command: built-in slash command to manage conversations.
Bulk delete: delete conversations and attached images in bulk, with progress feedback.
Session deep links: open Augment sessions via a VS Code URI handler.

MCP config power-ups: environment-variable expansion and working-directory injection in server configs.
MCP auth: RFC 8707 resource support and an "isReconnecting" status indicator.
Hooks: new PromptSubmit event, PreToolUse hooks can modify tool input, and .sh hooks now run on Windows.

Switched syntax highlighting from Monaco to Shiki for richer, more accurate highlighting.
Updated markdown rendering.
The code block "Create" action is hidden when the target file already exists.

A Retry button (with clearer wording) appears when a response is interrupted, plus a neutral retry message when recovering a lost stream.
A fork notice now appears in the edit-message input.
Smart/curly quotes are sanitized from model output.
Newlines and plain text are preserved when pasting into the chat input.
Pinned files are retained after the first message in a new conversation.
Image-attachment size limits are consistent across the UI.

Export Logs defaults to the workspace root, persists augment.log across sessions with daily rotation, and moved above Sign Out in the menu.
Settings spacing fixes and a dedicated Notifications category.
Fixed duplicate OS notification sounds and a secrets-manager modal overflow with long names.

More reliable webview startup via a longer gRPC handshake timeout and gRPC initialization retries.
The model registry recovers after transient feature-flag fetch failures.
Fixed VS Code getting stuck loading after an auth-session reload, and hardened daemon auth-session file handling.
Faster, non-blocking keybinding watching and isolated shell history for internal terminals.
API errors are no longer blocked on telemetry reporting; oversized files are skipped during indexing.
Long responses are supported with a 10-minute chat stream timeout.

Fixed PostHog MCP OAuth, ~ path expansion, OAuth clientId passthrough, and allowing multiple remote MCP servers with the same URL; unauthenticated MCP servers now show an Authenticate button.

Fixed the image-attachment "X" not removing the chip.
Fixed selecting a new thread for editor slash actions.
Removed a spurious trailing underscore on agent responses.
The back-to-parent button is hidden when there's no parent conversation.
Fixed patch-tool truncation; grep-search and oversized diffs now fail gracefully.
Hardened chat persistence to prevent crashes.
Clicking a desktop notification focuses the correct VS Code window.
Fixed duplicate-key rendering errors after the Svelte 5.54 upgrade.
Centered the send icon and fixed tabs overlapping on zoom.
Fixed rules file path validation and deduplicated skills in the slash menu.
Removed the Next Edit feature.
