New Features¶ ↑

• An any_not_empty extension has been added, for making Dataset#any? without a block be the same as !empty?. This can result in a much faster database query.

• An exclude_or_null extension has been added, adding a Dataset#exclude_or_null method that returns rows where the given expression is false or NULL. This extension is supported on PostgreSQL, SQLite, MySQL, H2, and HSQLDB.

Other Improvements¶ ↑

• When using the jdbc/postgresql adapter, calling with_fetch_size on a dataset will emit a warning. This is because the driver will ignore the setting.
