Fixes¶
Updated
log4j
to 2.15.0 to fix a security vulnerability. See Log4Shell for details.Fixed an issue that could result in an error if a client sent multiple statements in a single string using the PostgreSQL simple protocol mode.
Improved the detection of the cgroup version to support kernels where the cpu.stat and memory.stat files weren’t available at the cgroup root level.
Fixed an issue that could cause a deadlock, leading to an unavailable cluster if using blob tables and uploading multiple files in parallel.
Fixed an issue that was triggered by adding a column to a table with existing generated columns with ALTER TABLE. It caused the generated columns to become non-generated such that it could no longer generate the values.
