a|*Metric Rename – Cache Miss Ratio → Get Miss Ratio*
22+
The _Cache Miss Ratio_ metric name suggested it measured memory or disk caching performance.
23+
In practical instances, as of version 7.6.2, it was redefined to measure the proportion of read (`get`) operations that fail because the requested key is not present in the bucket at all.
24+
To eliminate this confusion, the metric has been renamed to *Get Miss Ratio*.

a|Prior to the 7.6.8 release, the auto-failover pop up alerts, as documented in link:https://docs.couchbase.com/server/current/manage/manage-settings/configure-alerts.html#saving-and-testing-the-alert-configuration[Saving and Testing the Alert Configuration] did not work.

a|The `magma_min_value_block_size_threshold` has been adjusted to INT_MAX for version 7.6.x, ensuring that block compression applies consistently for documents larger than 64 KiB.
51+
This change is not required for version 8.0.0 due to differences in configuration management.
52+
Couchbase recommends that if `magma_per_document_compression_enabled` is set to false, `magma_min_value_block_size_threshold` should also be set to `infinity` to maintain compression behavior.
53+
This resolves an issue with the Magma storage engine not compressing documents during persistence, which has been addressed in recent builds.
54+
The changes are confirmed and the ticket is closed after reviewing the code updates.

a|When modifying filter expressions or mapping configurations (explicit/migration), race conditions may prevent proper replication from the source.
86+
This can result in source bucket documents failing to replicate to the target bucket.
87+
To address this issue, the system now displays an alert when detecting replication resuming from stale checkpoints.
88+
This alert notifies users to delete and recreate the affected replication.
89+
IMPORTANT: Do not dismiss this alert by pausing and resuming the replication, as this will hide the warning without resolving the underlying issue.

a|Added a plan version to prepared statements and logic to trigger reprepare when outdated plans are detected.

a|The recent builds of Couchbase Server versions 7.2.7 through 8.1.0 and Enterprise Analytics 2.1.0 include updates from the `go_json` library to address int64 overflow issues reported under MB-67849.
115+
The updates involve implementing proper checks for int64 overflow to properly represent large numbers (greater than 2^63^or less than -2^63^).

a|Previously in clusters with the backup service running on multiple nodes it was possible for more than one task on a repo to be attempted at the same, causing all but one of these tasks to fail.
141+
If multiple tasks are scheduled to run at the same time, we now skip all but the first one.
