+\section*{Credits: version 8.7}
+
+{\Coq} version 8.7 contains the result of refinements, stabilization of
+features and cleanups of the internals of the system along with a few
+new features. The main user visible changes are:
+\begin{itemize}
+\item New tactics: variants of tactics supporting existential variables
+  \texttt{eassert}, \texttt{eenough}, etc... by Hugo Herbelin. Tactics
+  \texttt{extensionality in H} and \texttt{inversion\_sigma} by Jason
+  Gross, \texttt{specialize with ...} accepting partial bindings by
+  Pierre Courtieu.
+\item Cumulative Polymorphic Inductive Types, allowing cumulativity of
+  universes to go through applied inductive types, by Amin Timany and
+  Matthieu Sozeau.
+\item Integration of the \texttt{SSReflect} plugin and its documentation in the
+  reference manual, by Enrico Tassi, Assia Mahboubi and Maxime Dénès.
+\item The \texttt{coq\_makefile} tool was completely redesigned to improve its
+  maintainability and the extensibility of generated Makefiles, and to
+  make \texttt{\_CoqProject} files more palatable to IDEs by Enrico Tassi.
+\end{itemize}
+
+{\Coq} 8.7 involved a large amount of work on cleaning and speeding up
+the code base, notably the work of Pierre-Marie Pédrot on making the
+tactic-level system insensitive to existential variable expansion,
+providing a safer API to plugin writers and making the code more
+robust. The \texttt{dev/doc/changes.txt} file documents the numerous
+changes to the implementation and improvements of interfaces. An effort
+to provide an official, streamlined API to plugin writers is in
+progress, thanks to the work of Matej Košík.
+
+Version 8.7 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 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.
+
+Thomas Sibut-Pinote and Hugo Herbelin added support for side effects
+hooks in \texttt{cbv}, \texttt{cbn} and \texttt{simpl}.  The side
+effects are provided via a plugin available at
+\url{https://github.com/herbelin/reduction-effects/}.
+
+The \texttt{BigN}, \texttt{BigZ}, \texttt{BigQ} libraries are no longer
+part of the {\Coq} standard library, they are now provided by a separate
+repository \url{https://github.com/coq/bignums}, maintained by Pierre
+Letouzey.
+
+In the \texttt{Reals} library, \texttt{IZR} has been changed to produce
+a compact representation of integers and real constants are now
+represented using \texttt{IZR} (work by Guillaume Melquiond).
+
+Standard library additions and improvements by Jason Gross, Pierre
+Letouzey and others, documented in the CHANGES file.
+
+The mathematical proof language/declarative mode plugin was removed from
+the archive.
+
+The OPAM repository for {\Coq} packages has been maintained by Guillaume
+Melquiond, Matthieu Sozeau, Enrico Tassi with contributions from many
+users. A list of packages is 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 for MacOS X. Packages are regularly built on the
+Travis continuous integration server.
+
+The contributors for this version are Abhishek Anand, C.J. Bell, Yves
+Bertot, Frédéric Besson, Tej Chajed, Pierre Courtieu, Maxime Dénès,
+Julien Forest, Gaëtan Gilbert, Jason Gross, Hugo Herbelin, Emilio Jesús
+Gallego Arias, Ralf Jung, Matej Košík, Xavier Leroy, Pierre Letouzey,
+Assia Mahboubi, Cyprien Mangin, Erik Martin-Dorel, Olivier Marty,
+Guillaume Melquiond, Sam Pablo Kuper, Benjamin Pierce, Pierre-Marie
+Pédrot, Lars Rasmusson, Lionel Rieg, Valentin Robert, Yann Régis-Gianas,
+Thomas Sibut-Pinote, Michael Soegtrop, Matthieu Sozeau, Arnaud Spiwack,
+Paul Steckler, George Stelle, Pierre-Yves Strub, Enrico Tassi, Hendrik
+Tews, Amin Timany, Laurent Théry, Vadim Zaliva and Théo Zimmermann.
+
+The development process was coordinated by Matthieu Sozeau with the help
+of Maxime Dénès, who was also in charge of the release process. Théo
+Zimmermann is the maintainer of this release.
+
+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 Jason Gross, Ralf Jung, Robbert Krebbers, Xavier Leroy,
+Clément Pit--Claudel and Gabriel Scherer. It would however be impossible
+to mention exhaustively the names of everybody who to some extent
+influenced the development.
+
+Version 8.7 is the second release of {\Coq} developed on a time-based
+development cycle. Its development spanned 9 months from the release of
+{\Coq} 8.6 and was based on a public road-map. It attracted many external
+contributions. Code reviews and continuous integration testing were
+systematically used before integration of new features, with an
+important focus given to compatibility and performance issues, resulting
+in a hopefully more robust release than {\Coq} 8.6 while maintaining
+compatibility.
+
+Coq Enhancement Proposals (CEPs for short) and open pull-requests
+discussions were used to discuss publicly the new features.
+
+The {\Coq} consortium, an organization directed towards users and
+supporters of the system, is now upcoming and will rely on Inria's
+newly created Foundation.
