+## 💘 TimescaleDB v2.18.1 and AWS Transit Gateway Support Generally Available
+<Label type="date">February 14, 2025</Label>
+
+### TimescaleDB v2.18.1 
+New services created in Timescale Cloud now use [TimescaleDB v2.18.1](https://github.com/timescale/timescaledb/releases/tag/2.18.1). Existing services will be automatically upgraded in their next maintenance window starting next week.
+
+This new release includes a number of bug fixes and small improvements including:
+
+* Faster columnar scans when using the hypercore table access method
+* Ensure all constraints are always applied when deleting data on the columnstore
+* Pushdown all filters on scans for UPDATE/DELETE operations on the columnstore
+
+###  AWS Transit Gateway support is now generally available!
+
+Timescale Cloud now fully supports [AWS Transit Gateway](https://docs.timescale.com/use-timescale/latest/security/transit-gateway/), making it even easier to securely connect your database to multiple VPCs across different environments—including AWS, on-prem, and other cloud providers.
+
+With this update, you can establish a peering connection between your Timescale Cloud services and an AWS Transit Gateway in your AWS account. This keeps your Timescale Cloud services safely behind a VPC while allowing seamless access across complex network setups.
