2026-09-21-deepseek-harness-breaking-changes-an-operator-hits-on-upgrade
Breaking changes an operator hits on upgrade. The parent’s rc.8 SQLite schema problem is moot: the SQLite backend is gone. Session logs migrate forward twice with no way back. On alpha, a failed hot reload can leave a half-applied config.
Channel: preview-or-beta. Half: defect. Date: 2026-08-27 to 2026-09-17.
Operator consequence: Export SQLite-backed sessions on <= 0.1.1 before upgrading. Back up $DSH_HOME before moving to 0.1.5 (no downgrade). Third-party plugins written for rc.8 need porting; the unaffiliated oh-my-dsh upgrade skill is linked from 0.1.2-rc.1 notes but is not a DeepSeek product. On alpha, after any live config edit, check --dump-config for the new state; a failed activation is not rolled back.
