+* Reject incomplete static-address loop-in signing responses without crashing
+  the daemon.
+  [PR #1282](https://github.com/lightninglabs/loop/pull/1282)
+
+* Reject invalid static-address loop-in fee quotes before creating invoices.
+  [PR #1281](https://github.com/lightninglabs/loop/pull/1281)
+
+* Reject invalid loop-in fee quotes before creating invoices.
+  [PR #1284](https://github.com/lightninglabs/loop/pull/1284)
+
+* The `postgres.maxconnections` option now limits the number of open
+  connections to the Postgres server. It was ignored before, so concurrent
+  requests could open more connections than the server accepts. If the option
+  isn't set, loopd now opens at most 25 connections. Migration connections
+  are returned to the pool, and waiting for the migration lock respects the
+  configured timeout.
+  [PR #1262](https://github.com/lightninglabs/loop/pull/1262)
+
+* A static address loop-in whose HTLC had already spent its deposits no
+  longer gives up the deposits when the server rejects the confirmation risk
+  wait, also when the rejection is handled again after a restart. The client
+  keeps the deposits locked and sweeps the HTLC timeout path once the HTLC
+  times out.
+  [PR #1278](https://github.com/lightninglabs/loop/pull/1278)
+
+* Setting a P2PKH or P2SH address or a raw public key as the autoloop
+  destination no longer crashes loopd. The address is now decoded for the
+  active network, and a raw public key is rejected. Instant Out also rejects
+  raw public keys as destinations, matching Loop Out.
+  [PR #1280](https://github.com/lightninglabs/loop/pull/1280)
+
+* Autoloop, Instant Out, static address withdrawals and manual HTLC sweeps now
+  reject destination addresses of another network, as Loop Out already did. If
+  the saved autoloop destination belongs to another network, loopd removes it
+  at startup, and autoloop pays to wallet addresses.
