New Presto releases ⭐
Presto v0.288 is now available.
Release highlights include:
- Improve handling of floating point numbers in Presto to consistently treat NaNs as larger than any other number and equal to itself. It also changes the handling of positive and negative zero to always be considered equal to each other. For more information, see RFC-0001-nan-definition.md. The new nan behavior can be disabled by setting the configuration property use-new-nan-definition to false. This configuration property is intended to be temporary to ease migration in the short term, and will be removed in a future release. #22386
- Add procedure expire_snapshots to remove old snapshots in Iceberg. #22609
- Add support for Iceberg REST catalog. #22417
- Add support for NOT NULL column constraints in the CREATE TABLE and ALTER TABLE statements. This only takes effect for Hive connector now. #22064
See full release notes.
