バージョン0.124.0

New Features

• The TUI now has quick reasoning controls: Alt+, lowers reasoning, Alt+. raises it, and accepted model upgrades now reset reasoning to the new model’s default instead of carrying over stale settings. (#18866, #19085)

• App-server sessions can now manage multiple environments and choose an environment and working directory per turn, which makes multi-workspace and remote setups easier to target precisely. (#18401, #18416)

• Added first-class Amazon Bedrock support for OpenAI-compatible providers, including AWS SigV4 signing and AWS credential-based auth. (#17820)

• Remote plugin marketplaces can now be listed and read directly, with more reliable detail lookups and larger result pages. (#18452, #19079)

• Hooks are now stable, can be configured inline in config.toml and managed requirements.toml, and can observe MCP tools as well as apply_patch and long-running Bash sessions. (#18893, #18385, #18391, #18888, #19012)

• Eligible ChatGPT plans now default to the Fast service tier unless you explicitly opt out. (#19053)

Bug Fixes

• Preserved Cloudflare cookies across approved ChatGPT hosts, reducing auth breakage in HTTP-backed ChatGPT flows. (#17783)

• Fixed remote app-server reliability issues so websocket events keep draining under load and shutdown no longer fails when the remote worker exits during cleanup. (#18932, #18936)

• Fixed permission-mode drift so /permissions changes survive side conversations and updated Full Access state is correctly reflected in MCP approval handling. (#18924, #19033)

• Fixed wait_agent so it returns promptly when mailbox work is already queued instead of waiting for a fresh notification or timing out. (#18968)

• Fixed local stdio MCP launches for relative commands without an explicit cwd, bringing fallback path resolution in line with CLI behavior. (#19031)

• Startup now fails less often on managed config edge cases: unknown feature requirements warn instead of aborting, and cloud-requirements errors are clearer about what failed. (#19038, #19078)
