+### Breaking
+
+* [[#3821]] Groundwork for 0.9.0-alpha.1
+  * Increased MSRV to 1.86 and set rust-version [@abonander]
+  * Deleted deprecated combination runtime+TLS features (e.g. `runtime-tokio-native-tls`)
+  * Deleted re-export of unstable `TransactionManager` trait in `sqlx`.
+    * Not technically a breaking change because it's `#[doc(hidden)]`, 
+      but [it _will_ break SeaORM][seaorm-2600] if not proactively fixed.
