 ## Iris master
 
-Coq 8.10, 8.11, and 8.12 are newly supported by this release, and Coq 8.7 and
-8.8 are no longer supported.
+This release does not have any outstanding highlights, but contains a large
+amount of improvements all over the board.  For instance:
+
+* `heap_lang` now supports deallocation as well as better reasoning about
+  "invariant locations" that are not deallocated and whose value satisfies some
+  Coq-level invariant.
+* Invariants (`inv N P`) are more flexible, now also supporting splitting
+  and merging of invariants with respect to separating conjunction.
+* Performance of the proofmode for BIs constructed on top of other BIs (e.g.,
+  `monPred`) was greatly improved, leading to up to 70% speedup in individual
+  files. As part of this refactoring, the proofmode can now also be instantiated
+  with entirely "logical" notion of BIs that do not have a metric structure, and
+  still support reasoning about â–·.
+* Iris now provides official ASCII notation. We still recommend using the
+  Unicode notation for better consistency and interoperability with other Iris
+  libraries, but provide ASCII notation for when Unicode is not an option.
+* We removed several coercions, fixing "ambiguous coercion path" warnings and
+  solving some readability issues.
+* The proof mode now provides experimental support for naming pure facts in
+  intro patterns.  See
+  [iris/string-ident](https://gitlab.mpi-sws.org/iris/string-ident) for details.
+* Coq 8.10, 8.11, and 8.12 are newly supported by this release, and Coq 8.7 and
+  8.8 are no longer supported.
+
+Further details are given in the changelog below.
