Added a plugin system that can load skills, MCP entries, and app connectors from config or a local marketplace, with an install endpoint for enabling plugins from the app server. (#12864, #13333, #13401, #13422)
Expanded the TUI multi-agent flow with approval prompts, /agent-based enablement, clearer prompts, ordinal nicknames, and role-labeled handoff context. (#12995, #13246, #13404, #13412, #13505)
Added a persisted /fast toggle in the TUI and app-server support for fast and flex service tiers. (#13212, #13334, #13391)
Improved memories with workspace-scoped writes, renamed memory settings, and guardrails against saving stale or polluted facts. (#13008, #13088, #13237, #13467)
Added a direct Windows installer script to published release artifacts. (#12741)

Bug Fixes

Fixed @ file mentions so parent-directory .gitignore rules no longer hide valid repository files. (#13250)
Made sub-agents faster and more reliable by reusing shell state correctly and fixing /status, Esc, pending-message handling, and startup/profile race conditions. (#12935, #13052, #13130, #13131, #13235, #13240, #13248)
Fixed project trust parsing so CLI overrides apply correctly to trusted project-local MCP transports. (#13090)
Fixed read-only sandbox policies so network access is preserved when it is explicitly enabled. (#13409)
Fixed multiline environment export capture and Windows state DB path handling in session state. (#12642, #13336)
Fixed ANSI/base16 syntax highlighting so terminal-themed colors render correctly in the TUI. (#13382)

Documentation

Expanded app-server docs around service tiers, plugin installation, renaming unloaded threads, and the new skills/changed notification. (#13282, #13391, #13414, #13422)

Chores

Removed the remaining legacy app-server v1 websocket/RPC surfaces in favor of the current protocol. (#13364, #13375, #13397)
