ReleasePort's take

Light signal

editorial:auto 6d

Packaged installs without bundled AionCore now display a recovery screen with download link and diagnostic report instead of failing silently. Cross‑architecture builds correctly bundle the matching AionCore binary, eliminating previous mismatches.

Why it matters: Fixes silent failures for installations lacking AionCore (severity 40) and ensures correct architecture‑specific binaries are bundled, preventing runtime mismatches.

Highlights

Faster Conversations

Re-opening a conversation no longer pays for refetching every long tool output up front — full tool content is loaded on demand when you expand a truncated tool call, so big histories open noticeably faster.
Removed redundant warmup and MCP sync work on the message-send path so the first reply in a conversation arrives sooner, especially on aionrs and ACP backends.

Model Selector Reliability

Switching the model inside a conversation now sticks: leaving and returning to the conversation keeps your chosen model, and the home page dropdown remembers the last choice across ACP, aionrs, and team views.

Bug Fixes

Packaged installs that ship without bundled AionCore now show a clear recovery screen with a download link and diagnostic report action instead of failing silently; release builds also verify the bundled runtime during packaging so this can't ship broken again.
Provider health checks in Settings now use a dedicated probe and surface the backend's real error message — no more stale "error" text or temporary conversation rows polluting your sidebar.
Cross-architecture builds (e.g. Mac x64 from an arm runner) now bundle the matching AionCore binary instead of the runner's architecture.
