package ocamlmig

5.4-20251020

• Switch to ocaml 5.4

5.3-20250429

• Switch to ocaml 5.3.
• Added experimental ocamlmig replace command, for a sed-like rewrites but working on ASTs instead of bytes.
• Reduce slightly dependency on ocamlformat, so this can be used on the compiler codebase
• Added ocamlmig check to typecheck the replacement in things like val foo : int [@migrate { repl = bar }]

5.2-20250228

• Added support for rewriting .mli files, not just .ml files.
• First stab at supporting migrating modules: module Old_name : sig end .... [@@migrate { repl = New_name }]. These annotations are only looked for when passing -module-migration, and the replacement is limited to a module path.
• given an annotation val x : ... [@@migrate { repl = e }], when inserting e at a use-site of x, in some case we now modify e to avoid shadowing-related issues, and shorten module paths according to the modules opened in that scope.
• added an experimental printer that ocamlformats only the sections of the code that are modified, instead of the entire file. It is used by default when a repository does not use ocamlformat.
• ocamlmig transform rescope -unopen now knows to rename identifiers in all namespaces (module identifiers, type constructors, class identifiers, etc), instead of only values.
