Chores

• Use the Messages API exclusively for the official DeepSeek adapter and reuse uploaded images through the Files API. Migrate legacy protocol settings and Chat Completions URLs. by @LegGasai, @tianyicui
• Disable Ralph by default. Enable it explicitly if needed. by @tianyicui
• Remove the built-in E2B execution backends; update custom configurations that use them. by @tianyicui
• Rename PTC packages and services to the ptc-runtime family without legacy aliases; update custom plugins and configurations. by @tianyicui
• Replace the workflow executor with workflow-ptc under the session file policy; update custom configurations. Python PTC is not supported. by @tianyicui
• Replace agent/session-start with asynchronous, serial agent/created initialization; the first model request waits for completion. Update affected plugins and registration calls. by @kermanx
• Deprecate the synchronous Session history APIs snapshotEvents, eventAt, and ownEvents. by @kermanx
• Use spawn_teammate in experimental Team mode, disable subagent and subagent_fork, and raise the default teammate creation limit from 8 to 16. by @Dudu-0223
• Run Node PTC in separate processes under the session file policy with output and heap limits; process.env is empty, so code relying on the previous environment must migrate. by @tianyicui
• Remove transactional rollback from hot reload: parse failures preserve the original configuration, while activation failures may leave partial changes that require correction. by @turtle1999
• Make SandboxProvider.confine and ShellExecutor.start cancellable and asynchronous, with preparation included in timeouts; fix POSIX symlink/parent-directory combinations and Windows drive-relative paths. by @tianyicui
• Remove V4 Flash and V4 Flash Vision Exp from the default model list. by @tianyicui
• Continuable Subagent chains default to at most 8 live children and a delegation depth of 1, adjustable in settings. by @Dudu-0223, @ZiyaZhang

• Upgrade Session logs to V4 and add a batch migration tool for developers, including support for some V3 histories with missing turn-end records. by @tianyicui, @kermanx
• Attachments stored only in custom events are no longer read or exported automatically; plugins must adapt. by @tianyicui
• Allow plugins to declare localized titles and descriptions through the locale data structure and icons in package.json for display in Plugin Manager. by @imccyu, @turtle1999
