DeepTutor v1.5.1 Release Notes
Release Date: 2026.07.09
A small release on top of v1.5.0: a knowledge base stuck in an error state is no longer a dead end — you can drop the single document that failed and keep going, instead of deleting and rebuilding the whole base. Drop-in — no migrations.
What's New
Remove a single document — even from an error-state KB
You can now delete one raw document from a knowledge base in the Files tab, and it works even while the KB is in an error state. Previously a file that failed to parse (for example, a PDF over the cloud parser's page limit) left the whole base locked, and the only escape was to delete and rebuild it from scratch. Now you drop just the offending file, upload a replacement, or retry indexing from the documents that remain. Removal is decoupled from the index — it never needs a working index to run — so any vectors from an already-indexed file are simply cleared on the next re-index.
Upgrade Notes
Drop-in from v1.5.0: pip install -U deeptutor; Docker users pull ghcr.io/hkuds/deeptutor:latest. No migrations and no behavior changes — existing knowledge bases, partners, and mastery paths keep working as-is. Connected (read-only) and legacy knowledge bases still reject per-file deletion, as before.
