v1.4.0

Released: 2026-09-09

Changed

• The seven in-repo SDKs now use agent-history-v2, with schema version 1.
  The generic localOnly status property is removed. CLI status and setup JSON
  use schema version 3; generic usage/error, index and daemon envelopes use
  schema version 2. Update consumers that require the old field or check these
  versions; the migration guide
  covers the affected APIs. Operation-specific Semantic diagnostics retain
  their execution-location information.

Fixed

• Semantic search shows and cites the passage that earned the result's score.
• Semantic document chunks no longer lose their final tokens to tokenizer
  truncation.
• Codex imports preserve distinct item and tool-call identities when both are
  present in a transcript.
• Failed index rebuilds clean up their abandoned candidate files. Disk-pressure
  reports use the observed free space.

GitHub downloads contain unmanaged Core-only binaries. The
hosted installer installs the managed Core and Pro pair.
Existing managed installations move through the 1.3.2 bridge before 1.4.0.
Windows 0.25.0 users must stop any opted-in legacy ctx daemon and rerun the
PowerShell installer.
