2.19.2

This release contains bug fixes since the 2.19.1 release. We recommend that you \ 
upgrade at the next available opportunity.

2.19.1

This release contains bug fixes since the 2.19.0 release. We recommend that you \ 
upgrade at the next available opportunity.

2.19.0

This release contains performance improvements and bug fixes since the 2.18.2 \ 
release. We recommend that you upgrade at the next available opportunity.

Improved concurrency of INSERT, UPDATE, and DELETE operations on the columnstore \ 
by no longer blocking DML statements during the recompression of a chunk.
Improved system performance during continuous aggregate refreshes by breaking \ 
them into smaller batches. This reduces systems pressure and minimizes the risk \ 
of spilling to disk.
Faster and more up-to-date results for queries against continuous aggregates by \ 
materializing the most recent data first, as opposed to old data first in prior \ 
versions.
Faster analytical queries with SIMD vectorization of aggregations over text \ 
columns and GROUP BY over multiple columns.
Enable optimizing the chunk size for better query performance in the columnstore \ 
by merging them with merge_chunk.

postgresql-timescaledb: updated to 2.18.0

2.18.0 (2025-01-23)

This release introduces the ability to add secondary indexes to the columnstore, \ 
improves group by and filtering performance through columnstore vectorization, \ 
and contains the highly upvoted community request of transition table support. \ 
We recommend that you upgrade at the next available opportunity.

Highlighted features in TimescaleDB v2.18.0

The ability to add secondary indexes to the columnstore through the new \ 
hypercore table access method.
Significant performance improvements through vectorization (SIMD) for \ 
aggregations using a group by with one column and/or using a filter clause when \ 
querying the columnstore.
Hypertables support triggers for transition tables, which is one of the most \ 
upvoted community feature requests.
Updated methods to manage Timescale's hybrid row-columnar store (hypercore) that \ 
highlight the usage of the columnstore which includes both an optimized columnar \ 
format as well as compression.

2.17.0 (2024-10-08)

This release adds support for PostgreSQL 17, significantly improves the \ 
performance of continuous aggregate refreshes, and contains performance \ 
improvements for analytical queries and delete operations over compressed \ 
hypertables.
We recommend that you upgrade at the next available opportunity.

Highlighted features in TimescaleDB v2.17.0

Full PostgreSQL 17 support for all existing features. TimescaleDB v2.17 is \ 
available for PostgreSQL 14, 15, 16, and 17.

Significant performance improvements for continuous aggregate policies:
Continuous aggregate refresh is now using merge instead of deleting old \ 
materialized data and re-inserting. This update can decrease dramatically the \ 
amount of data that must be written on the continuous aggregate in the presence \ 
of a small number of changes, reduce the i/o cost of refreshing a continuous \ 
aggregate, and generate fewer Write-Ahead Logs (WAL). Overall, continuous \ 
aggregate policies will be more lightweight, use less system resources, and \ 
complete faster.

Increased performance for real-time analytical queries over compressed hypertables:
We are excited to introduce additional Single Instruction, Multiple Data (SIMD) \ 
vectorization optimization to our engine by supporting vectorized execution for \ 
queries that group by using the segment_by column(s) and aggregate using the \ 
basic aggregate functions (sum, count, avg, min, max).
Stay tuned for more to come in follow-up releases! Support for grouping
on additional columns, filtered aggregation,
vectorized expressions, and time_bucket is coming soon.

Improved performance of deletes on compressed hypertables when a large amount of \ 
data is affected.
This improvement speeds up operations that delete whole segments by skipping the \ 
decompression step. It is enabled for all deletes that filter by the segment_by \ 
column(s).
