2.13.0 (2023-11-28)

This release contains performance improvements, an improved hypertable DDL API
and bug fixes since the 2.12.2 release. We recommend that you upgrade at the next
available opportunity.

In addition, it includes these noteworthy features:

* Full PostgreSQL 16 support for all existing features
* Vectorized aggregation execution for sum()
* Track chunk creation time used in retention/compression policies

**Deprecation notice: Multi-node support**
TimescaleDB 2.13 is the last version that will include multi-node support. Multi-node
support in 2.13 is available for PostgreSQL 13, 14 and 15. Learn more about it
[here](docs/MultiNodeDeprecation.md).

If you want to migrate from multi-node TimescaleDB to single-node TimescaleDB \ 
read the
[migration \ 
documentation](https://docs.timescale.com/migrate/latest/multi-node-to-timescale-service/).

**PostgreSQL 13 deprecation announcement**
We will continue supporting PostgreSQL 13 until April 2024. Sooner to that time, \ 
we will announce the specific version of TimescaleDB in which PostgreSQL 13 \ 
support will not be included going forward.
