https://github.com/coq/coq/releases/tag/V8.8.0 Coq version 8.8 contains the result of refinements and stabilization of features and deprecations, cleanups of the internals of the system along with a few new features. Summary of changes Kernel: fix a subject reduction failure due to allowing fixpoints on non-recursive values (#407), by Matthieu Sozeau. Handling of evars in the VM (#935) by Pierre-Marie Pédrot. Notations: many improvements on recursive notations and support for destructuring patterns in the syntax of notations by Hugo Herbelin. Proof language: tacticals for profiling, timing and checking success or failure of tactics by Jason Gross. The focusing bracket { supports single-numbered goal selectors, e.g. 2:{, (#6551) by Théo Zimmermann. Vernacular: cleanup of definition commands (#6653) by Vincent Laporte and more uniform handling of the Local flag (#1049), by Maxime Dénès. Experimental Show Extraction command (#6926) by Pierre Letouzey. Coercion now accepts Prop or Type as a source (#6480) by Arthur Charguéraud. Export modifier for options allowing to export the option to modules that Import and not only Require a module (#6923), by Pierre-Marie Pédrot. Universes: many user-level and API level enhancements: qualified naming and printing, variance annotations for cumulative inductive types, more general constraints and enhancements of the minimization heuristics, interaction with modules by Gaëtan Gilbert, Pierre-Marie Pédrot and Matthieu Sozeau. Library: Decimal Numbers library (#6599) by Pierre Letouzey and various small improvements. Documentation: a large community effort resulted in the migration of the reference manual to the Sphinx documentation tool. The new documentation infrastructure (based on Sphinx) is by Clément Pit-Claudel. The migration was coordinated by Maxime Dénès and Paul Steckler, with some help of Théo Zimmermann during the final integration phase. The 14 people who ported the manual are Calvin Beck, Heiko Becker, Yves Bertot, Maxime Dénès, Richard Ford, Pierre Letouzey, Assia Mahboubi, Clément Pit-Claudel, Laurence Rideau, Matthieu Sozeau, Paul Steckler, Enrico Tassi, Laurent Théry, Nikita Zyuzin. Tools: experimental -mangle-names option to coqtop/coqc for linting proof scripts (#6582), by Jasper Hugunin.

https://github.com/coq/coq/releases/tag/V8.9.0 Coq version 8.9 contains the result of refinements and stabilization of features and deprecations or removals of deprecated features, cleanups of the internals of the system and API along with a few new features. 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. 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 Numeral Notation command for registering decimal numeral notations for custom types, by Daniel de Rauglaudre, Pierre Letouzey and Jason Gross. Tactics: Introduction tactics intro/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 lia and removal of fourier, replaced by lra which subsumes it, by Frédéric Besson, Maxime Dénès, Vincent Laporte and Laurent Théry. Proof language: focusing bracket { now supports named goals, 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. Vernacular: Experimental support for 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 Arguments, with the help of Jasper Hugunin. New flag Uniform Inductive Parameters by Jasper Hugunin to avoid repeating uniform parameters in constructor declarations. New commands Hint Variables and 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 Create HintDb. Multiple sections with the same name are now allowed, by Jasper Hugunin. Library: additions and changes in the VectorDef, Ascii, and String libraries. 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 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.
