+## 0.5.6 - 2021-08-16
+
+A large bugfix release, including but not limited to:
+
+* [[#1329]] Implement `MACADDR` type for Postgres [[@nomick]]
+* [[#1363]] Fix `PortalSuspended` for array of composite types in Postgres [[@AtkinsChang]]
+* [[#1320]] Reimplement `sqlx::Pool` internals using `futures-intrusive` [[@abonander]]
+    * This addresses a number of deadlocks/stalls on acquiring connections from the pool.
+* [[#1332]] Macros: tell the compiler about external files/env vars to watch [[@abonander]]
+    * Includes `sqlx build-script` to create a `build.rs` to watch `migrations/` for changes.
+    * Nightly users can try `RUSTFLAGS=--cfg sqlx_macros_unstable` to tell the compiler 
+      to watch `migrations/` for changes instead of using a build script. 
+    * See the new section in the docs for `sqlx::migrate!()` for details.
+* [[#1351]] Fix a few sources of segfaults/errors in SQLite driver [[@abonander]]
+    * Includes contributions from [[@link2ext]] and [[@madadam]].
+* [[#1323]] Keep track of column typing in SQLite EXPLAIN parsing [[@marshoepial]]
+    * This fixes errors in the macros when using `INSERT/UPDATE/DELETE ... RETURNING ...` in SQLite.
