Announcing: Citus 11.1 open source release

## Shard your Postgres tables without blocking writes

New in the Citus 11.1 database, you can now distribute Postgres tables, split shards, and isolate tenants—without interruption, which means without blocking writes. Also included in 11.1 is PostgreSQL 15 beta 4 support, plus shard rebalancing in the background. Read [Marco’s blog post](https://www.citusdata.com/blog/2022/09/19/citus-11-1-shards-postgres-tables-without-interruption/) for the full story. Or if you’re more interested in the code you can check out the [Citus GitHub repo](https://github.com/citusdata/citus) (feel free to give the project a star to show support :) ).

## Citus is now 100% open source
In the last release (11.0), you gained the ability to [query from any node](https://www.citusdata.com/blog/2022/06/17/citus-11-goes-fully-open-source/), opening up Citus for many new use cases, and we also [made Citus fully open source](https://www.citusdata.com/blog/2022/09/12/distributed-postgres-goes-full-open-source-with-citus/).

## About the Citus database extension
Citus is a distributed database built entirely as an [open source extension for PostgreSQL](https://youtu.be/JwjjUT8K7po). With Citus, you can create tables that are transparently distributed or replicated across a cluster of PostgreSQL nodes. Citus is available as [open source](https://www.citusdata.com/download/) and also as a [managed service on Azure](https://aka.ms/docs-citus-on-azure).
