+
+### Fixed
+
+- Fixed OpenCode chats failing with "Variant unavailable" after switching to a model without the selected thinking level ([#5587](https://github.com/getpaseo/paseo/pull/5587))
+- Fixed rewinding a Codex chat dropping its custom provider and Paseo tools ([#5345](https://github.com/getpaseo/paseo/pull/5345) by [@zbaibg](https://github.com/zbaibg))
+- Fixed streamed replies joining lines of code blocks and Mermaid diagrams until the chat reloads ([#5577](https://github.com/getpaseo/paseo/pull/5577))
+- Fixed a subagent opened from a split pane opening in a different pane ([#5451](https://github.com/getpaseo/paseo/pull/5451))
+- Fixed archiving a custom Codex provider's agent leaving its session in Import session ([#5572](https://github.com/getpaseo/paseo/pull/5572))
+- Fixed the `/` menu of a custom Codex provider with its own `CODEX_HOME` listing the daemon's prompts instead of its own ([#5450](https://github.com/getpaseo/paseo/pull/5450))
+- Fixed a background `send_agent_prompt` returning `idle` for a prompt the agent accepted ([#5386](https://github.com/getpaseo/paseo/pull/5386))
+- Fixed Windows file-link tooltips showing the full path for files inside the workspace ([#1987](https://github.com/getpaseo/paseo/pull/1987))

Mohamed Boudra	9f387873b0	fix(opencode): clear unsupported thinking when changing models (#5587 ) Resolve retained variants against the destination model before applying a model change. Publish the effective thinking choice and refresh the provider resume handle immediately so a reload cannot restore the old selection.

Qi	12cd5345d2	feat(claude): add Sonnet 5.5 with its model capabilities (#5583 ) Claude Code 2.1.284 introduces Sonnet 5.5 with a native 1M context window, medium default effort, and adaptive thinking that cannot be turned off, so it takes the same shape as Opus 5.5 in the manifest. Sonnet 5.5 rejects `thinking: {"type": "disabled"}` with a 400, so its entry omits supportsThinkingDisabled and its thinking options have no off. It also takes the Sonnet family tagline, which moves Sonnet 5 to Previous release. The catalog gates the entry on Claude Code 2.1.284, the version that recognizes the model, so older installs keep their current catalog. The existing major-minor runtime matching already resolves dashed gateway IDs such as us.anthropic.claude-sonnet-5-5-20260928-v1:0 to the new entry without collapsing them onto Sonnet 5.

paseo-bot[bot]	2c6d4e5283	fix(app): keep line breaks in streamed replies when a chunk ends in indentation (#5577 ) While a reply streams, presentation reparses only the growing last Markdown block: the cached block text plus the new chunk. splitMarkdownBlocks drops a trailing whitespace-only line, and only trailing "\n"s were added back, so a reply that paused on "]\n " cached the block as "]". The next chunk " B -->" then continued the previous line, joining two lines of a code block. Codex streams a line break and the next line's indent as separate deltas, so its Mermaid diagrams hit this and failed to render. History reparses the whole text, which is why a reload showed the reply correctly. Keep every trailing blank line the split drops on the last block.

paseo-bot[bot]	006bae2897	Archive a custom Codex provider's session when its agent is archived (#5572 ) A provider that extends Codex runs through the registry's client wrapper, which forwarded session listing and import but not native archive or unarchive. Archiving such an agent left its Codex thread unarchived, so the session stayed in Import session and could be imported again. The wrapper now forwards both, the same as stock Codex.
