This release includes many user-visible changes, including +deprecations that are documented in ``CHANGES.md`` and new features that +are documented in the reference manual. Here are the most important +changes: + +- Kernel: mutually recursive records are now supported, by Pierre-Marie + Pédrot. + +- Notations: + + - Support for autonomous grammars of terms called "custom entries", by + Hugo Herbelin (see section :ref:`custom-entries` of the reference + manual). + + - Deprecated notations of the standard library will be removed in the + next version of |Coq|, see the ``CHANGES.md`` file for a script to + ease porting, by Jason Gross and Jean-Christophe Léchenet. + + - Added the :cmd:`Numeral Notation` command for registering decimal + numeral notations for custom types, by Daniel de Rauglaudre, Pierre + Letouzey and Jason Gross. + +- Tactics: Introduction tactics :tacn:`intro`/:tacn:`intros` on a goal that is an + existential variable now force a refinement of the goal into a + dependent product rather than failing, by Hugo Herbelin. + +- Decision procedures: deprecation of tactic ``romega`` in favor of + :tacn:`lia` and removal of ``fourier``, replaced by :tacn:`lra` which + subsumes it, by Frédéric Besson, Maxime Dénès, Vincent Laporte and + Laurent Théry. + +- Proof language: focusing bracket ``{`` now supports named + :ref:`goals <curly-braces>`, e.g. ``[x]:{`` will focus + on a goal (existential variable) named ``x``, by Théo Zimmermann. + +- SSReflect: the implementation of delayed clear was simplified by + Enrico Tassi: the variables are always renamed using inaccessible + names when the clear switch is processed and finally cleared at the + end of the intro pattern. In addition to that the use-and-discard flag + `{}` typical of rewrite rules can now be also applied to views, + e.g. `=> {}/v` applies `v` and then clears `v`. See section + :ref:`introduction_ssr`. + +- Vernacular: + + - Experimental support for :ref:`attributes <gallina-attributes>` on + commands, by Vincent Laporte, as in ``#[local] Lemma foo : bar.`` + Tactics and tactic notations now support the ``deprecated`` + attribute. + + - Removed deprecated commands ``Arguments Scope`` and ``Implicit + Arguments`` in favor of :cmd:`Arguments`, with the help of Jasper + Hugunin. + + - New flag :flag:`Uniform Inductive Parameters` by Jasper Hugunin to + avoid repeating uniform parameters in constructor declarations. + + - New commands :cmd:`Hint Variables` and :cmd:`Hint Constants`, by + Matthieu Sozeau, for controlling the opacity status of variables and + constants in hint databases. It is recommended to always use these + commands after creating a hint databse with :cmd:`Create HintDb`. + + - Multiple sections with the same name are now allowed, by Jasper + Hugunin. + +- Library: additions and changes in the ``VectorDef``, ``Ascii`` and + ``String`` library. Syntax notations are now available only when using + ``Import`` of libraries and not merely ``Require``, by various + contributors (source of incompatibility, see `CHANGES.md` for details). + +- Toplevels: ``coqtop`` and ``coqide`` can now display diffs between proof + steps in color, using the :opt:`Diffs` option, by Jim Fehrle. + +- Documentation: we integrated a large number of fixes to the new Sphinx + documentation by various contributors, coordinated by Clément + Pit-Claudel and Théo Zimmermann. + +- Tools: removed the ``gallina`` utility and the homebrewed ``Emacs`` mode. + +- Packaging: as in |Coq| 8.8.2, the Windows installer now includes many + more external packages that can be individually selected for + installation, by Michael Soegtrop. + +Version 8.9 also comes with a bunch of smaller-scale changes and +improvements regarding the different components of the system. Most +important ones are documented in the ``CHANGES.md`` file. + +On the implementation side, the ``dev/doc/changes.md`` file documents +the numerous changes to the implementation and improvements of +interfaces. The file provides guidelines on porting a plugin to the new +version and a plugin development tutorial kept in sync with Coq was +introduced by Yves Bertot http://github.com/ybertot/plugin_tutorials. +The new ``dev/doc/critical-bugs`` file documents the known critical bugs +of |Coq| and affected releases. + +The efficiency of the whole system has seen improvements thanks to +contributions from Gaëtan Gilbert, Pierre-Marie Pédrot, and Maxime Dénès. + +Maxime Dénès, Emilio Jesús Gallego Arias, Gaëtan Gilbert, Michael +Soegtrop, Théo Zimmermann worked on maintaining and improving the +continuous integration system. + +The OPAM repository for |Coq| packages has been maintained by Guillaume +Melquiond, Matthieu Sozeau, Enrico Tassi with contributions from many +users.
