# Release notes for Managed Databases
## 2026 \{#2026}
July
* added the `pg_uuidv7` extension for PostgreSQL and PostgreSQL TimescaleDB.
Learn more about extensions in the instructions for [PostgreSQL](/managed-databases/postgresql/add-extensions.mdx) and [PostgreSQL TimescaleDB](/managed-databases/timescaledb/add-extensions.mdx).
June
* added new extensions for PostgreSQL and PostgreSQL TimescaleDB:
* `pg_cron;`
* `pg_prewarm.`
Learn more about extensions in the instructions for [PostgreSQL](/managed-databases/postgresql/add-extensions.mdx) and [PostgreSQL TimescaleDB](/managed-databases/timescaledb/add-extensions.mdx);
* added new [events](/audit-logs/events.mdx#dbaas) to audit logs:
* `dbaas.cluster_pooler.update;`
* `dbaas.cluster_security_group.update;`
* `dbaas.cluster_config.update;`
* `dbaas.cluster_log_platform.enable;`
* `dbaas.cluster_log_platform.disable;`
* `dbaas.cluster_firewall_rule.update;`
* `dbaas.cluster_backup.update.`
* launched a new DBMS [ClickHouse®](/managed-databases/clickhouse) in beta. Availability of the DBMS in regions is provided in the [Cloud Databases](/infrastructure/availability-matrix.mdx#managed-databases) subsection of the [Availability Matrix](/infrastructure/availability-matrix.mdx).
ClickHouse® is a registered trademark of ClickHouse, Inc. https://clickhouse.com;
* updated the **Network** section on the cluster creation page — information about routers connected to existing subnets is now displayed when a network is selected.
May
* updated the list of supported PostgreSQL versions: removed version 13 in Cloud Databases [PostgreSQL](/managed-databases/postgresql/configurations.mdx#versions), [PostgreSQL for 1C](/managed-databases/postgresql-for-1c/configurations.mdx#versions) and [PostgreSQL TimescaleDB](/managed-databases/timescaledb/configurations.mdx#versions);
* added support for Cloud Databases in [audit logs](/audit-logs/about-audit-logs.mdx) — [dbaas service](/audit-logs/events.mdx#dbaas).
April
* Cloud Databases are now available in the [multi-zone pool](/infrastructure/locations.mdx#multi-az-pool) ru-6. In this pool, you can create clusters with Multi-AZ node placement — nodes are guaranteed to be distributed across several data centers in different [availability zones](/infrastructure/locations.mdx#availability-zone). Learn more in the Cluster Fault Tolerance instructions for the relevant DBMS in the [Cloud Databases](/managed-databases/);
* added the ability to manage the `maxmemory` parameter in Redis [version](/managed-databases/redis/configurations.mdx#versions) 8. Learn more in the [Redis Eviction Policies](/managed-databases/redis/eviction-policy.mdx);
* changed the price block when [creating](/managed-databases/opensearch/create-cluster.mdx) and [scaling an OpenSearch cluster](/managed-databases/opensearch/resize-cluster.mdx) — now it displays prices for each [node group](/managed-databases/opensearch/about-node-groups.mdx);
* added the `jsonb_plperl` extension for PostgreSQL and PostgreSQL TimescaleDB.
Learn more about extensions in the instructions for [PostgreSQL](/managed-databases/postgresql/add-extensions.mdx) and [PostgreSQL TimescaleDB](/managed-databases/timescaledb/add-extensions.mdx).
March
* updated configuration limits for the Flex line. For example, for [PostgreSQL](/managed-databases/postgresql/configurations.mdx#flex-line);
* added a new [version](/managed-databases/redis/configurations.mdx#versions) of Redis 8.
January
* updated the interface in the [Control Panel](https://my.selectel.ru/vpc/default/dbaas/) on the OpenSearch cluster page:
* simplified the information display in node group cards;
* improved the readability of configurations.
## 2025 \{#2025}
December
* added a new [version](/managed-databases/kafka/configurations.mdx#versions) of Kafka 4.1;
* added the new Mega configuration to the Dedicated line:
* CPU: Intel® Xeon® Gold 6336Y 2.4 GHz / 3.6 GHz Turbo Boost, 46 vCPU;
* RAM: 706 GB DDR4 ECC Reg;
* disks: 27.1 TB SSD NVMe, performance — read 1 500 000 IOPS / write 750 000 IOPS, bandwidth — 7 000 MB/s;
* added new extensions for PostgreSQL and PostgreSQL TimescaleDB:
* `pg_buffercache;`
* `clickhouse_fdw;`
* `oracle_fdw.`
Learn more about extensions in the instructions for [PostgreSQL](/managed-databases/postgresql/add-extensions.mdx) and [PostgreSQL TimescaleDB](/managed-databases/timescaledb/add-extensions.mdx);
* added new settings for PostgreSQL, PostgreSQL for 1C, and PostgreSQL TimescaleDB:
* `log_min_duration_statement;`
* `log_lock_waits;`
* `log_temp_files;`
* `track_io_timing;`
* `track_functions;`
* `transaction_timeout.`
These parameters allow you to flexibly configure logging and monitoring and more accurately analyze DBMS performance for specific load profiles;
* updated the [Control Panel](https://my.selectel.ru/vpc/default/dbaas/):
* sped up cluster loading by region;
* updated the DBMS and version selection screen on the cluster creation page;
* updated the **Network** block and public access settings for cluster nodes on the cluster creation page.
November
* added new extensions for PostgreSQL and PostgreSQL TimescaleDB:
* `pg_trgm;`
* `tsm_system_rows;`
* `tsm_system_time;`
* `tcn;`
* `plpgsql.`
Learn more about extensions in the instructions for [PostgreSQL](/managed-databases/postgresql/add-extensions.mdx) and [PostgreSQL TimescaleDB](/managed-databases/timescaledb/add-extensions.mdx);
* added new configurations to the Dedicated line:
* Micro
CPU: Intel® Xeon® E-2488 3.2 GHz / 5.6 GHz Turbo Boost, 14 vCPU;
RAM: 32 GB DDR5 ECC Reg;
disks: 0.5 TB SSD NVMe, performance — read 700 000 IOPS / write 180 000 IOPS, bandwidth — 7 000 MB/s;

RAM: 64 GB DDR5 ECC Reg;
disks: 1 TB SSD NVMe, performance — read 700 000 IOPS / write 180 000 IOPS, bandwidth — 7 000 MB/s;
* improved monitoring graphs for clusters, nodes, and databases in the [Control Panel](https://my.selectel.ru/vpc/default/dbaas/). You can now open graphs in full screen, toggle metrics, and display data for multiple nodes on a graph;
* updated interface elements in the [Control Panel](https://my.selectel.ru/vpc/default/dbaas/): texts, icons, and indentation;
* redesigned the configuration selection algorithm when creating and scaling a cluster.
