## 2.17.0

This release contains performance improvements and bug fixes since
the 2.16.1 release. We recommend that you upgrade at the next
available opportunity.

**Features**
* timescale#6882: Allow DELETE on the compressed chunks without decompression.
* timescale#7033 Use MERGE statement on CAgg Refresh
* timescale#7126: Add functions to show the compression information.
* timescale#7147: Vectorize partial aggregation for `sum
* timescale#7204: Track additional extensions in telemetry.
* timescale#7207: Refactor the `decompress_batches_scan` functions for easier maintenance.
* timescale#7209: Add a function to drop the `osm` chunk.

**Bugfixes**
* timescale#7187: Fix the string literal length for the `compressed_data_info` function.
* timescale#7191: Fix creating default indexes on chunks when migrating the data.
* timescale#7195: Fix the `segment by` and `order by` checks when dropping a column from a compressed hypertable.
* timescale#7201: Use the generic extension description when building `apt` and `rpm` loader packages.
* timescale#7227: Add an index to the `compression_chunk_size` catalog table.
* timescale#7229: Fix the foreign key constraints where the index and the constraint column order are different.
* timescale#7230: Do not propagate the foreign key constraints to the `osm` chunk.
* timescale#7234: Release the cache after accessing the cache entry.
* timescale#7258 Force English in the pg_config command executed by cmake to avoid unexpected building errors
* timescale#7270 Fix memory leak in compressed DML batch filtering

**Thanks**
* @MiguelTubio for reporting and fixing a Windows build error
* @posuch for reporting the misleading extension description in the generic loader packages.
