We are excited to announce that TimescaleDB 2.8 is available on Timescale Cloud and for download 
This major release comes with the following improvements and more:
The time_bucket hyperfunction now supports bucketing by month, year, and time zone, enabling easier time-based queries and reporting.
You can now manage refresh, compression, and retention policies for continuous aggregates all in one easy step.
Improved performance of bulk SELECT statements that fetch high volumes of data from distributed hypertables using the COPY protocol.
Support for ON CONFLICT ON CONSTRAINT UPSERT statements on TimescaleDB hypertables, which enables better compatibility with some GraphQL/ PostgreSQL middlewares.
