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)
