+## v0.0.2 — 2026-06-19
+
+### Fixed
+
+- **B2 backup failing with `NotImplementedError` after a TrueNAS update.**
+  The patch block's guard (`if "get_restic_config" not in B2RcloneRemote.__dict__`)
+  could misfire and silently skip injecting the method — most likely when a
+  TrueNAS version adds a stub that raises `NotImplementedError`, causing the dict
+  check to return `False`. The guard is removed; the assignment is now
+  unconditional. This is safe because the native-support kill switch already
+  prevents patching when TrueNAS ships a real, working implementation.
+
+- **Native-support check falsely triggering kill switch on stubs.**
+  The check now inspects the source of any pre-existing `get_restic_config`
+  before concluding that TrueNAS has shipped native B2 support. If the method
+  body contains `NotImplementedError` it is treated as a stub and patching
+  continues; only a method that does not raise `NotImplementedError` triggers
+  the kill switch and auto-disable.

+## v0.0.1 — 2026-06-16
+
+Initial public release. Extends TrueNAS SCALE's TrueCloud Backup feature to
+work with S3-compatible providers and native Backblaze B2 in addition to Storj,
+using volatile overlayfs patching of the TrueNAS middleware that persists across
+system updates via a PREINIT initshutdownscript.
+
+### Included
+
+- `install.sh` — registers the PREINIT boot hook and applies patches immediately
+- `patch/apply.sh` — PREINIT script; mounts writable overlays, patches `b2.py`
+  and `restic.py`, patches the Angular UI bundle to widen the credential dropdown
+- `patch/create_task.py` — CLI to create TrueCloud Backup tasks with S3 or B2
+  credentials, bypassing the Storj-only restriction in the UI
+- `recover.sh` — emergency recovery; sets the kill switch and restarts middlewared
+- `uninstall.sh` — full removal of the patch and PREINIT hook
+- Kill switch support (`disabled` file) for safe degradation
+- Auto-disable when TrueNAS ships native B2 restic support
+- `hook_status.json` written on each boot for `create_task.py verify`
