This release is medium priority for upgrade. We recommend that you upgrade at the next available opportunity. This release adds major new features since the 2.5.2 release, including: Compression in continuous aggregates Experimental support for timezones in continuous aggregates Experimental support for monthly buckets in continuous aggregates It also includes several bug fixes. Telemetry reports are switched to a new format, and now include more detailed statistics on compression, distributed hypertables and indexes. **Features** * #3768 Allow ALTER TABLE ADD COLUMN with DEFAULT on compressed hypertable * #3769 Allow ALTER TABLE DROP COLUMN on compressed hypertable * #3943 Optimize first/last * #3945 Add support for ALTER SCHEMA on multi-node * #3949 Add support for DROP SCHEMA on multi-node **Bugfixes** * #3808 Properly handle max_retries option * #3863 Fix remote transaction heal logic * #3869 Fix ALTER SET/DROP NULL contstraint on distributed hypertable * #3944 Fix segfault in add_compression_policy * #3961 Fix crash in EXPLAIN VERBOSE on distributed hypertable * #4015 Eliminate float rounding instabilities in interpolate * #4019 Update ts_extension_oid in transitioning state * #4073 Fix buffer overflow in partition scheme **Improvements** Query planning performance is improved for hypertables with a large number of chunks. **Thanks** * @fvannee for reporting a first/last memory leak * @mmouterde for reporting an issue with floats and interpolate
