 Brick changelog
 ---------------
 
+0.55
+----
+
+Package changes:
+ * Increased lower bound on `vty` dependency to 5.29.
+
+Bug fixes:
+ * `customMain` now restores the initial terminal input state on
+   shutdown. This means that changes to the input state flags in the last
+   `suspendAndResume` before program exit are no longer propagated to the
+   end user's terminal environment (which could lead to broken or garbled
+   terminal I/O).
+
