⚠️ Breaking changes

} + +- The deprecated high availability startup flags `--instance-down-timeout-sec` + and `--instance-health-check-frequency-sec` have been removed after two release + cycles. They were deprecated in 3.10 and ignored since then, but startup now + fails if either flag is still set. Remove them from coordinator configs and + use `SET COORDINATOR SETTING 'instance_down_timeout_sec' TO ''` and + `SET COORDINATOR SETTING 'instance_health_check_frequency_sec' TO ''` + instead. Values previously passed via the flags are not migrated automatically + — re-apply any non-default settings after upgrade. + [#4310](https://github.com/memgraph/memgraph/pull/4310) + +{

🛠️ Improvements

} + +- WAL files are now protected with CRC32 checksums. The WAL header and each + transaction carry their own checksum, which is verified during recovery and on + replicas before the data is applied, so silent on-disk corruption is detected + instead of being recovered. WAL files written by older versions remain + recoverable without verification. + [#4225](https://github.com/memgraph/memgraph/pull/4225) + +{

✨ New features

} + +- MAGE is now available as prebuilt RPM packages on CentOS 9 and CentOS 10, so + you can install the graph algorithm library with your package manager instead + of building from source. Install the matching `memgraph` package first, then + the `memgraph-mage` RPM. + [#4289](https://github.com/memgraph/memgraph/pull/4289) + +{

🐞 Bug fixes

} + +- Fixed `replace()` causing an infinite loop and OOM when the search string is empty. Empty search now inserts the replacement at every character boundary with bounded allocation, so queries such as `replace("abc", "", "-")` return `"-a-b-c-"` instead of crashing the server. [#4269](https://github.com/memgraph/memgraph/pull/4269) +- Fixed Bolt 4.4 clients receiving routing tables from data instances and + incorrectly defaulting the target database. Data instances now reject routing + requests, and database selection over Bolt 4.4 works as expected. + [#4270](https://github.com/memgraph/memgraph/pull/4270) + +### Lab v3.12.0 - July 29th, 2026 + + + +## Previous releases + ### Memgraph v3.11.0 - June 17th, 2026 {
