+# Percona Server for MongoDB 7.0.21-12 ({{date.7_0_21}})
+
+[Installation](../install/index.md){.md-button}
+[Upgrade from MongoDB Community](../install/upgrade-from-mongodb.md){.md-button}
+
+Percona Server for MongoDB 7.0.21-12 is an enhanced, source-available, and highly-scalable database that is a
+fully-compatible, drop-in replacement for MongoDB Community Edition.
+
+Percona Server for MongoDB 7.0.21-12 includes the improvements and bug fixes of [MongoDB 7.0.19 Community Edition](https://www.mongodb.com/docs/manual/release-notes/7.0/#7.0.19---apr-14--2025) through [MongoDB 7.0.21 Community Edition](https://www.mongodb.com/docs/manual/release-notes/7.0/#7.0.21---upcoming). It supports protocols and drivers of MongoDB versions 7.0.19 - 7.0.21.
+
+## Release highlights
+
+This release provides the following features and improvements:
+
+### Boost performance during cluster restore and scaling with file copy based initial sync
+
+You can now select how a newly added or a restored replica set member receives the data from other members - via logical or file copy based sync. File copy based sync is the copying of physical files rather than actual data clone. This makes this sync method is faster than the logical one and it reduces your maintenance time on scaling.
+
+This functionality is available in [Percona Server for MongoDB Pro](../psmdb-pro.md) out of the box. Become a Percona Customer to enjoy all Pro features with little to no effort from your side.
+
+
+
+### Upstream Improvements
+
+The bug fixes, provided by MongoDB Community and included in Percona Server for MongoDB, are the following:
+
+* [SERVER-93120](https://jira.mongodb.org/browse/SERVER-93120) - Fixed the issue with blocking Full Time Diagnostic Data Capture (FTDC) collection when checking the state of the bacupCursor by using atomic mode instead of a lock
+* [SERVER-92806](https://jira.mongodb.org/browse/SERVER-92806) -  Tracked nested paths through MatchExpression trees while encoding indexability for plan cache entries
+* [SERVER-95672](https://jira.mongodb.org/browse/SERVER-95672) - Fixed the issue with missing documents when indexes on array fields contain subarrays by ensuring proper bounds when having nested arrays as predicates
+* [SERVER-97044](https://jira.mongodb.org/browse/SERVER-97044) -  Fixed an issue where change streams might incorrectly output a "drop" event during resharding or unsharding of a collection that is or was using zone sharding
+* [WT-12012](https://jira.mongodb.org/browse/WT-12012) - Fixed the issue when a generation drain process in WiredTiger, which manages eviction of older data, encounters an issue and then resolves itself when the verbosity levels for eviction and checkpoint operations increase. The issue is fixed by restoring original verbosity levels for these operations.
