UTF-8 multi-byte characters in keyboard input: The key parser now correctly reassembles multi-byte UTF-8 sequences delivered as individual escape sequences. Previously, non-ASCII characters entered via the terminal (particularly on some Linux/remote terminals) could be dropped or misinterpreted. A pendingByteEvents buffer accumulates bytes and flushes the complete character once all bytes have arrived. (search for "pendingByteEvents")
AbortSignal memory leak in event listeners: Abort-signal subscriptions created during agent turns now use a FinalizationRegistry to automatically remove the listener when the child object is garbage-collected. Previously, long-running sessions with many tool calls could accumulate a growing number of stale abort listeners. (search for "FinalizationRegistry")
FileIndex: skip path normalization when unchanged: Path normalization is now skipped when the raw git paths have not changed, avoiding unnecessary work and a potential re-index cycle. (search for "[FileIndex] skipped path normalization")
FileIndex: discard mid-refresh results when cache was reset: If the file index cache is reset while a refresh is in progress, the results of that refresh are now discarded rather than written over the fresh cache. (search for "[FileIndex] discarding refresh results")
Windows: UNC watch paths dropped gracefully: When the file watcher encounters remote UNC paths on Windows, they are now silently dropped with a debug log rather than crashing the watcher. (search for "FileChanged: dropped remote UNC watch path(s)")
MCP schema validation error surfaced as named error: MCP tool results that fail schema validation now throw a McpResponseSchemaError with the validation message attached, rather than an untyped error. (search for "McpResponseSchemaError" or "MCP server returned a malformed result")
