Release 0.188

Fix inverted sign for time zones , Etc/GMT-11, …, Etc/GMT-1, , … Etc/GMT+12.
Reduce GC spikes by compacting join memory over time instead of all at once when memory is low. This can increase reliability at the cost of additional CPU. This can be enabled via the pages-index.eager-compaction-enabled config property.
Mitigate excessive GC and degraded query performance by forcing expiration of generated classes for functions and expressions one hour after generation.

Fix transaction support. Previously, after the first statement in the transaction, the transaction would be abandoned and the session would silently revert to auto-commit mode.
