+## 2026.4.15
+
+### Changes
+
+- Anthropic/models: default Anthropic selections, `opus` aliases, Claude CLI defaults, and bundled image understanding to Claude Opus 4.7.
+- Google/TTS: add Gemini text-to-speech support to the bundled `google` plugin, including provider registration, voice selection, WAV reply output, PCM telephony output, and setup/docs guidance. (#67515) Thanks @barronlroth.
+
+### Fixes
+
+- Agents/skills: sort prompt-facing `available_skills` entries by skill name after merging sources so `skills.load.extraDirs` order no longer changes prompt-cache prefixes. (#64198) Thanks @Bartok9.
+- Agents/context + Memory: trim default startup/skills prompt budgets, cap `memory_get` excerpts by default with explicit continuation metadata, and keep QMD reads aligned with the same bounded excerpt contract so long sessions pull less context by default without losing deterministic follow-up reads.
+- BlueBubbles/inbound: restore inbound image attachment downloads on Node 22+ by stripping incompatible bundled-undici dispatchers from the non-SSRF fetch path, accept `updated-message` webhooks carrying attachments, use event-type-aware dedup keys so attachment follow-ups are not rejected as duplicates, and retry attachment fetch from the BB API when the initial webhook arrives with an empty array. (#64105, #61861, #65430, #67510) Thanks @omarshahine.
+- CLI/update: prune stale packaged `dist` chunks after npm upgrades and keep downgrade/verify inventory checks compat-safe so global upgrades stop failing on stale chunk imports. (#66959) Thanks @obviyus.
+- Gateway/tools: anchor trusted local `MEDIA:` tool-result passthrough on the exact raw name of this run's registered built-in tools, and reject client tool definitions whose names normalize-collide with a built-in or with another client tool in the same request (`400 invalid_request_error` on both JSON and SSE paths), so a client-supplied tool named like a built-in can no longer inherit its local-media trust. (#67303)
+- OpenAI Codex/models: normalize stale native transport metadata in both runtime resolution and discovery/listing so legacy `openai-codex` rows with missing `api` or `https://chatgpt.com/backend-api/v1` self-heal to the canonical Codex transport instead of routing requests through broken HTML/Cloudflare paths, combining the original fixes proposed in #66969 (saamuelng601-pixel) and #67159 (hclsys). (#67635)
