DSH rc.4 + 0.2.2-alpha.2: ACP Leak Fix (Oct 28, 2026)

rc.4 Fixes an ACP stdout Leak and the 0.2.2 Series Opens at alpha.2 — 56 Seconds Later, with Six New Locales and Four Experimental Plugins.

The 0.2.1 series reached its release candidates on October 17, and the candidate line then went quiet for five days. On 2026-10-28 upstream moved twice within one minute: v0.2.1-rc.4 published at 02:49:58 UTC, and the 0.2.2 series opened beside it 56 seconds later with v0.2.2-alpha.2 at 02:50:54 UTC. Both carry the Pre-release flag.

rc.4: one fix, nine commits

rc.4’s notes hold a single Bug Fixes item: diagnostics leaking into stdout in ACP mode, by @LegGasai and @tianyicui. The rc.3…rc.4 compare (fetched 2026-10-28) holds nine commits and shows the fix’s footprint: resource-listing diagnostics kept off ACP stdout, account catalog diagnostics kept off stdout, and a shared-cleanup regression test, alongside two view-tab tooltip fixes the notes do not list and the release chore itself.

It is also the first release entry the 0.2.1 line has seen since v0.2.1-rc.3 on 2026-10-23, whose notes carried two improvements — More menus in the left sidebar, conversation views and right sidebar, and a fix for New Session losing an unsent draft after switching sessions — plus one chore bringing the DeepSeek API key adapter’s model-list updates in line with account sign-in.

alpha.2: the 0.2.2 line opens mid-series

The new series’ first public build is alpha.2. The repository’s tag list carries a single dsh-v0.2.2-* tag and the releases list has no alpha.1 entry, so there is no alpha.1 to summarize — and alpha.2’s own compare base is rc.4, not an earlier 0.2.2 build. What it carries is the series’ opening batch: per its bilingual notes, New Features holds eleven items — rich-text plugin details in the plugin manager; updating third-party plugin packages with an attempt to restore the previous version when a hot update fails; inserting chat text as quotes in the composer; copying complete conversation history as Markdown, log path included when available; keeping all assistant text replies visible when work steps collapse, with a final-answer-only option; Japanese, Spanish, French, German, Russian and Brazilian Portuguese interface text; clearing all inactive automation tasks in one confirmed action; and four experimental plugins — the subagent_oar tool delegating independent tasks to local Codex or Claude CLIs, Personalized recommendations, Developer tools — Statistics, and Change requests and worktrees running Sessions in separate Git worktrees with linked PR status and code changes.

As of this article’s 2026-10-28 fetch of the releases list, no stable build exists anywhere on the channel: all of 0.2.1 from alpha.1 through rc.4, and now the 0.2.2 line, carry the Pre-release flag.
