New plugins for translation and parallel work
The experimental reasoning-translation plugin can be enabled from the Plugins page. It offers Bing, Google and paid DeepSeek Flash as translation providers. 17
The experimental Git Worktrees plugin lets an agent create and enter an independent Git checkout. That gives agents a separate working copy for tasks that should be isolated from another checkout. The release also introduces session-state interfaces that let experimental plugins read and write their own session records. 17
More control over workspace instructions
The release adds a working_directory tool and TypeScript and Python SDK interfaces for reading and changing a session’s working directory. It also supports global instructions from an AGENTS.md file in a shared agents directory; DSH_AGENTS_HOME specifies that directory. 17
The Official plugin catalog adds on-demand, release-matched Claude Code and Codex bundles for headless, SDK and ACP profiles. 6
15
Remote execution and web hosting
For remote work, alpha.2 adds standalone executable SSH helper runtimes. The release notes list support for remote file operations, processes, terminals, sandboxing and Node PTC. 11
The web runtime can bind to a specified IPv4 or IPv6 address and serve HTTPS directly using --tls-cert and --tls-key. 11
Subagent and model-runtime changes
Subagent execution and completion notification are unified. Subagent tools now return a child ID immediately, so custom SDK runtimes need to support session/wait to wait for the child’s result. This is a compatibility point for teams maintaining their own runtimes. 11
17
The release also updates bundled pi-ai to version 1.0.2. Its routes support in-conversation system-prompt updates and dynamic tool additions or removals according to model capabilities. 11
What to keep in mind
This is an alpha pre-release, not a stable version. The changes most likely to affect custom integrations are the new working-directory APIs and the requirement for custom SDK runtimes to handle the session/wait flow. 9
