Over the +year of (now time-based) development, about 450 bugs were resolved and +over 100 contributions integrated. The main user visible changes are: +\begin{itemize} +\item A new, faster state-of-the-art universe constraint checker, by + Jacques-Henri Jourdan. +\item In CoqIDE and other asynchronous interfaces, more fine-grained + asynchronous processing and error reporting by Enrico Tassi, making {\Coq} + capable of recovering from errors and continue processing the document. +\item More access to the proof engine features from Ltac: goal + management primitives, range selectors and a {\tt typeclasses + eauto} engine handling multiple goals and multiple successes, by + Cyprien Mangin, Matthieu Sozeau and Arnaud Spiwack. +\item Tactic behavior uniformization and specification, generalization + of intro-patterns by Hugo Herbelin and others. +\item A brand new warning system allowing to control warnings, turn them + into errors or ignore them selectively by Maxime Dénès, Guillaume + Melquiond, Pierre-Marie Pédrot and others. +\item Irrefutable patterns in abstractions, by Daniel de Rauglaudre. +\item The {\tt ssreflect} subterm selection algorithm by Georges Gonthier and + Enrico Tassi is now accessible to tactic writers through the {\tt ssrmatching} + plugin. +\item Integration of {\tt LtacProf}, a profiler for {\tt Ltac} by Jason + Gross, Paul Steckler, Enrico Tassi and Tobias Tebbi. +\end{itemize} + +{\Coq} 8.6 also comes with a bunch of smaller-scale changes and +improvements regarding the different components of the system. We shall +only list a few of them. + +The {\tt iota} reduction flag is now a shorthand for {\tt match}, {\tt + fix} and {\tt cofix} flags controlling the corresponding reduction +rules (by Hugo Herbelin and Maxime Dénès). + +Maxime Dénès maintained the native compilation machinery. + +Pierre-Marie Pédrot separated the Ltac code from general purpose +tactics, and generalized and rationalized the handling of generic +arguments, allowing to create new versions of Ltac more easily in the +future. + +In patterns and terms, {\tt @}, abbreviations and notations are now +interpreted the same way, by Hugo Herbelin. + +Name handling for universes has been improved by Pierre-Marie Pédrot and +Matthieu Sozeau. The minimization algorithm has been improved by +Matthieu Sozeau. + +The unifier has been improved by Hugo Herbelin and Matthieu Sozeau, +fixing some incompatibilities introduced in Coq 8.5. Unification +constraints can now be left floating around and be seen by the user +thanks to a new option. The {\tt Keyed Unification} mode has been +improved by Matthieu Sozeau. + +The typeclass resolution engine and associated proof-search tactic have +been reimplemented on top of the proof-engine monad, providing better +integration in tactics, and new options have been introduced to control +it, by Matthieu Sozeau with help from Théo Zimmermann. + +The efficiency of the whole system has been significantly improved +thanks to contributions from Pierre-Marie Pédrot, Maxime Dénès and +Matthieu Sozeau and performance issue tracking by Jason Gross and Paul +Steckler. + +Standard library improvements by Jason Gross, Sébastien Hinderer, Pierre +Letouzey and others. + +Emilio Jesús Gallego Arias contributed many cleanups and refactorings of +the pretty-printing and user interface communication components. + +Frédéric Besson maintained the micromega tactic. + +The OPAM repository for {\Coq} packages has been maintained by Guillaume +Claret, Guillaume Melquiond, Matthieu Sozeau, Enrico Tassi and others. A +list of packages is now available at \url{https://coq.inria.fr/opam/www/}. + +Packaging tools and software development kits were prepared by Michael +Soegtrop with the help of Maxime Dénès and Enrico Tassi for Windows, and +Maxime Dénès and Matthieu Sozeau for MacOS X. Packages are now regularly +built on the continuous integration server. {\Coq} now comes with a {\tt + META} file usable with {\tt ocamlfind}, contributed by Emilio Jesús +Gallego Arias, Gregory Malecha, and Matthieu Sozeau. + +Matej Košík maintained and greatly improved the continuous integration +setup and the testing of {\Coq} contributions. He also contributed many +API improvement and code cleanups throughout the system. + +The contributors for this version are Bruno Barras, C.J. Bell, Yves +Bertot, Frédéric Besson, Pierre Boutillier, Tej Chajed, Guillaume +Claret, Xavier Clerc, Pierre Corbineau, Pierre Courtieu, Maxime Dénès, +Ricky Elrod, Emilio Jesús Gallego Arias, Jason Gross, Hugo Herbelin, +Sébastien Hinderer, Jacques-Henri Jourdan, Matej Kosik, Xavier Leroy, +Pierre Letouzey, Gregory Malecha, Cyprien Mangin, Erik Martin-Dorel, +Guillaume Melquiond, Clément Pit--Claudel, Pierre-Marie Pédrot, Daniel +de Rauglaudre, Lionel Rieg, Gabriel Scherer, Thomas Sibut-Pinote, +Matthieu Sozeau, Arnaud Spiwack, Paul Steckler, Enrico Tassi, Laurent +Théry, Nickolai Zeldovich and Théo Zimmermann. The development process +was coordinated by Hugo Herbelin and Matthieu Sozeau with the help of +Maxime Dénès, who was also in charge of the release process. + +Many power users helped to improve the design of the new features via +the bug tracker, the pull request system, the {\Coq} development mailing +list or the coq-club mailing list. Special thanks to the users who +contributed patches and intensive brain-storming and code reviews, +starting with Cyril Cohen, Jason Gross, Robbert Krebbers, Jonathan +Leivent, Xavier Leroy, Gregory Malecha, Clément Pit--Claudel, Gabriel +Scherer and Beta Ziliani. It would however be impossible to mention +exhaustively the names of everybody who to some extent influenced the +development. + +Version 8.6 is the first release of {\Coq} developed on a time-based +development cycle. Its development spanned 10 months from the release of +{\Coq} 8.5 and was based on a public roadmap. To date, it contains more +external contributions than any previous {\Coq} system. Code reviews +were systematically done before integration of new features, with an +important focus given to compatibility and performance issues, resulting +in a hopefully more robust release than {\Coq} 8.5. + +Coq Enhancement Proposals (CEPs for short) were introduced by Enrico +Tassi to provide more visibility and a discussion period on new +features, they are publicly available \url{https://github.com/coq/ceps}. + +Started during this period, an effort is led by Yves Bertot and Maxime +Dénès to put together a {\Coq} consortium. + +\begin{flushright} +Paris, November 2016,\\ +Matthieu Sozeau and the {\Coq} development team\\ +\end{flushright} + %new Makefile |
