Version 3.0.0

Backward incompatible changes are marked with “⚠”.

• New option tuareg-mode-line-other-file.
• New mode tuareg-menhir-mode.
  Note that C-c C-c launches the compilation.
• ⚠ tuareg-eval-phrase (C-c C-e and C-x C-e) now
  evaluate the smallest set of phrases containing the region if the
  latter is active.
• ⚠ tuareg-eval-phrase now skips ;; even on a separate line when moving
  forward. This permits quick evaluation of multiple phrases in succession.
• ⚠ tuareg-eval-region (C-c C-r): only send the content of
  the region to the REPL.
• Be more subtle in phrase detection.
• Bogus mismatched parentheses at the end of comment fixed.
• ⚠ show-paren-mode: also highlight comment delimiters. You can
  turn that off by setting tuareg-comment-show-paren to nil.
• Syntax highlighting improvements: much faster; much better highlighting
  of function, class, and method arguments (including setting the
  font-lock-multiline property); [] and :: have the constructor
  face; first class module, type nonrec, raise_notrace, with type are handled. Finer highlighting of infix operators. Support
  for binding operators. Moreover, font-lock now has 3 possible
  levels of fontification (see the README).
• The switch .ml ↔ .mli now uses the Emacs built-in find-file and
  was extended to .eliom ↔ .eliomi and .mly ↔ .mli. It also
  works for pre-processed files named .pp.ml and .pp.mli.
• When switching from an .ml to a non-existing .mli file using
  C-c C-a, one is offered to fill the .mli buffer with the
  generated interface.
• Set beginning-of-defun-function and end-of-defun-function which
  allows to go to the beginning of the current function (resp. end)
  with C-M-home, C-M-a or ESC
  C-home (resp. C-M-end, C-M-e, or
  ESC C-end).
• ⚠ beginning-of-defun (C-M-a, C-M-home) is
  now repeatable. Previously it would not move the cursor if invoked
  at the beginning of a defun. Now it goes to the start of the
  previous defun, which is the standard in Emacs and generally more
  useful.
• ⚠ Movement by defun now considers and clauses of a type or
  declarative let to be defuns in their own right, since that's
  closer to how programmers think. This generally makes defun-based
  operations more useful.
• ⚠ tuareg-comment-dwim is now bound to C-c C-; (fixes #149).
• Fix the highlighting of errors locations in interactive mode.
• ocamldebug: Handle correctly the new code pointer format (issue #205).
• Rework electric functions (fixes issues #150 and #162).
• Update the compilation regexp to detect warnings and errors for the
  OCaml ≥ 4.08 (fixes #202).
• Autoload compilation error regexp so it is correct even if Tuareg
  was not loaded.
• Messages from recent OCaml compiler versions are now parsed
  correctly for severity and source location. This includes precise
  parsing of the location start and end columns. Exception backtraces
  are now also recognised.
• Ancillary locations are now treated as Info-level messages, not
  errors in their own right. This way they no longer contribute to
  Emacs's compilation-mode error count, but they will be ignored by
  next-error and previous-error. Set compilation-skip-threshold
  to 0 if you want next-error to step into these locations.
• Evaluation of phrases: evaluate the above phrase if the point is in
  or after comments immediately following the let-binding (without
  separating blank lines).
• Better indentation of empty lines (fixes #179).
• Use a pty to communicate with the ocaml process (fixes #83).
• tuareg-opam: syntax highlighting updates.
• ⚠ Remove tuareg-light, you should now use tuareg.
• class type is now parsed correctly (#239).
• Improved indentation of class definition with non-hanging object (#239).
  The new behaviour agrees with ocp-indent and seems to be the more modern
  usage. initialize clauses are also indented correctly.
• Better default colour for extension nodes on dark background.
  tuareg-font-lock-extension-node-face was nigh-unreadable against
  a dark background. The face now uses the default background colour.
• Ocamldoc (** ... *) comments are now fontified by their structure.
  This makes markup constructs stand out in order to improve legibility
  and reduces the risk of mistakes. The body text is set in
  font-lock-doc-face as before; mark-up constructs use
  tuareg-font-lock-doc-markup-face, which defaults to
  font-lock-doc-markup-face (new in Emacs 28) if available.

Note that the mode tuareg-dune which was in the development version
of this package is now part of Dune.
