 **Syntax**
 
 - Fix printing for inline nullary functor types [#477](https://github.com/rescript-lang/syntax/pull/477)
 - Fix stripping of quotes for empty poly variants [#474](https://github.com/rescript-lang/syntax/pull/474)

 - Fix parsing of first class module exprs as part of binary/ternary expr in [#256](https://github.com/rescript-lang/syntax/pull/256)
+* Fix formatter hanging on deeply nested function calls [#261](https://github.com/rescript-lang/syntax/issues/261)
+* Remove parsing of "import" and "export" which was never officially supported.
+* Doc comments `/** ... */` are now supported. Inernally, they are attributes, so are only valid at positions where `@foo` is allowed, or a syntax error is given. Similarly for module-level `/*** comments */` that can go where `@@attributes` go.
 
 **Libraries**
 
+* Removed printing modules (Printf, Format etc) and related functions. Details of files added/removed: https://github.com/rescript-lang/rescript-compiler/commit/0fd8bb0e77c4b0e96a9647ac8af614305057003f.
+- There could be issues with `rescript-relay`. See https://github.com/rescript-lang/rescript-compiler/issues/5493.
 - Several Belt libraries are now converted to ReScript syntax, with corresponding comments in Markdown format suitable for hovering.
