+Sat Feb  7 21:14:00 UTC 2026 - Holden Fried <holden@opensuse.org>
+
+- Update to release v1.36.1
+  * Interactive TUI for monitoring various filesystem internals,
+    slowpaths and device performance, with duration and frequency
+    tracking for various events. Helpful for diagnosing performance
+    issues.
+  * `encoded_extent_max` default bumped to 256k; new filesystems
+    now initialize `BCH_SB_EXTENT_BP_SHIFT` to 16, so higher
+    settings won't require rebuilding backpointers
+  * `--rotational` flag now works correctly during format
+  * Copygc now waits until a device is less than 20% free before
+    starting
+  * Improved `bcachefs reconcile status` output
+  * Large batch of erasure coding cleanup and hardening: better
+    error reporting for EC reconstruct reads, fix a race between EC
+    and data moves, and various other EC bugfixes
+  * Fix write buffer `move_keys_from_inc_to_flushing()` regression,
+    which was causing occasional oopses under load for some users
+  * Snapshot deletion is now much faster when deleting large
+    numbers of snapshos; we now use an eytzinger tree for the list
+    of nodes being deleted
+  * Fix sporadic superblock checksum failures during device scan
+  * Many smaller bugfixes
+
+- Update to release v1.36.0
+  * bcachefs_metadata_version_no_sb_user_data_replicas
+  * This requires an incompatible upgrade to enable, and once
+    enabled we'll no longer store replicas entries in the
+    superblock for user data, which are used for deciding whether
+    we an do a degraded mount without data loss - instead, we defer
+    that and use the accounting btree to check, in early recovery.
+  * This is a performance/scalability fix: on filesystems with
+    large numbers of drives (a 50 device filesystem was the
+    original bug report), the superblock writes needed to add and
+    delete replicas entries become a bottleneck.
+  * Replicas entries for metadata (btree and journal) can still be
+    an issue, and another bug report indicated that these will have
+    to be addressed soon - a single slow (or dying) device in a
+    large multidevice will cause all superblock writes to slow to a
+    degree that can cause major problems. Metadata replicas entries
+    will however require a different approach to solve, so expect
+    that in a future update.
+  * Some fairly involved fixes for the data update path: it turns
+    out, the data update path was dropping replicas to devices
+    being evacuated (which are considered to have durability of 0)
+    before the extent was sufficiently replicated on other devices.
+    This caused data loss for a few users, unfortunately, but the
+    new code is much more rigorous when reconciling the exsiting
+    extent with newly written replicas and deciding which replicas
+    to keep and which can be dropped.
+  * Fix various codepaths that were (incorrectly) causing the
+    filesystem to go emergency read-only when finding a pointer to
+    an invalid device, instead of continuing so it could be
+    repaired or flagging the filesystem as needing repair. We now
+    should only go emergency read-only on pointer to invalid device
+    when that would indicate a runtime bug, not filesystem
+    corruption.
+  * Reconcile will now shut down correctly (when the filesystem is
+    going read-only or unmounting) when processing the
+    reconcile_*_phys btrees.
+  * Multiple other smaller reconcile fixes; various users report
+    that issues where reconcile did not seem to be finding pending
+    work seem to be resolved.
+  * Degraded btree nodes are no longer un-degraded synchronously;
+    now that we have reconcile this is no longer necessary, and
+    forcing them to be un-degraded synchronously was prone to
+    causing deadlocks on open_bucket allocation.
+  * The 'allocator stuck' log message now provides improved
+    information, and internally has been re-plumbed to have access
+    to the original 'struct alloc_request', so if necessary for
+    future debugging we can easily provide as much information
+    about how the allocation was attempted as required.

+Sun Jan 25 21:16:08 UTC 2026 - Holden Fried <holden@opensuse.org>
+
+- Update to release 1.35.2
+  * Linux v6.19 is now supported
+  * Reconcile now considers the amount of durability we have
+    available among online devices when dropping extra replicas
+    (because the replicas setting was changed), and won't let the
+    online durability go below the replicas setting.
+  * Fix a race in the nocow write path when checking if we need to
+    fall back to a normal COW write
+  * Fix a livelock when walking btree roots in reconcile and
+    elsewhere
+  * Journal discards are now done asynchronously instead of being
+    done by the journal reclaim thread, and we try to keep more of
+    the journal discarded to avoid journal writes having to block
+    and do discards synchronously
+  * Fix several bugs with copygc <-> reconcile interaction, and
+    copygc should no longer spin when a device is completely full
+    with no fragmented buckets for it to evacuate.
+  * Fix propagating the incompressible bit in the data update
+    path: sometimes this would be lost, leading to spurious
+    "extent with bad/missing reconcile options" errors.
+- Update to release 1.35.1
+  * Self healing for the new stripe refcount field in
+    `bch_alloc_v4`
+  * This fixes issues upgrading to 1.35 with (still experimental)
+    erasure coding feature.
+  * Major allocator refactoring, simplifying the central control
+    flow. Prep work for failure domains.
+  * Erasure coding can now delete stripes from triggers; this
+    gives better behaviour when data being deleted with no other
+    activity to cause stripes to be deleted.
+  * Fix a deadlock in device add when allocating journal on the
+    new device; this fixes a regression from the watermark cleanup.
