| Ten changes from [@brettwooldridge](https://github.com/brettwooldridge), most of them found on a production system. Four are data-integrity fixes, three of which can end with a store that will not reopen or a query that quietly returns the wrong rows. | |||

Reconcile the documented change count and references.
Line 3 says “Ten changes”, but the file contains 12 top-level entries and 11 unique pull request references. Line 7 references #1301, while the PR objectives identify #1304 as the other superseding pull request. Confirm the intended scope, then update the count and links so the release notes match the PR.
This comparison uses the PR objectives.

## Unreleasedrather than a version. This repo's convention puts the heading and the pom bump in onerelease Xcommit (as 65caa56 did for 5.3.0), and cutting the release is yours to call. 5.4.0 looks right: four data-integrity fixes and two changed defaults, no API removals.Two behaviour changes callers should see before upgrading, both written up in the entry:
MVStoreModuleBuilder.pageSplitSizedefaults to 16 KB instead of 16 bytes (fix: default MVStore pageSplitSize to 16 KB, not 16 bytes #1293). Existing files are unaffected until their pages are rewritten.retentionTime(0)restores the old behaviour.Also worth knowing: a unique index migrates from the
value -> [id]list layout tovalue -> idthe first time it is accessed (#1295), and reads now cost a deep structural copy rather than a shallow one (#1294).Two things I found while merging that the entry records because they were not in any PR description:
IndexManagerbug in perf: store a unique index as one id per key instead of a one-element list #1295 (close/clearAll/dropIndexDescriptoracting only on the map name inIndexMeta) is what brokeChangeIdField— a re-created index found the previous layout map still populated and rebuilt over it. It was masked until fix: leave MVStore's chunk retention and versions-to-keep at H2's defaults #1303 stopped the store panicking at close first.MigrationTestfailures on CI (Chunk.accountForRemovedPage,Double mark) were the 0/0 retention corruption, not flaky tests.🤖 Generated with Claude Code
