1+### Version 0.7.0.0 (2023-07-31)

2+

3+ * Remove Eq Null instance. (Future `base` may break it, we remove it profilacticly).

4+ * Use `postgresql-libpq >=0.10.0.0`. It includes critical fixes,

5+ by using `postgresql-simple >=0.7` you won't get older `postgresql-libpq`.

6+ * Drop support for GHC prior 8.6

7+ * Added a class for `postgresql-simple` exceptions: `SomePostgreSqlException`.

8+ This allows to catch all `postgresql-simple` exceptions at once.

9+ (c.f. `AsyncException` in `base).

10+

11+### Version 0.6.5.1 (2023-07-09)
