 - Config: keep legacy audio transcription migration strict by rejecting non-string/unsafe command tokens while still migrating valid custom script executables. (#5042) Thanks @shayan919293.
 - Status/Sessions: stop clamping derived `totalTokens` to context-window size, keep prompt-token snapshots wired through session accounting, and surface context usage as unknown when fresh snapshot data is missing to avoid false 100% reports. (#15114) Thanks @echoVic.
 - Providers/MiniMax: switch implicit MiniMax API-key provider from `openai-completions` to `anthropic-messages` with the correct Anthropic-compatible base URL, fixing `invalid role: developer (2013)` errors on MiniMax M2.5. (#15275) Thanks @lailoo.
+- Config: accept `$schema` key in config file so JSON Schema editor tooling works without validation errors. (#14998)
