== Enhancements to SchemaManager

Two new methods were added to `SchemaManager`:

- `resynchronizeGenerators()` force all sequences to catch up with data imported to their corresponding tables
- `truncateTable()` truncates a single table and resets its corresponding primary key sequence

In addition, `truncate()` now automatically resets all primary key sequences and tables backing table generators.

== Regular expression support in HQL

The operators `like regexp` and `ilike regexp` were added to HQL, allowing {versionDocBase}/querylanguage/html_single/#like-predicate[patterns to be written as regular expressions].
