Dear Coq clubbers,

  The Coq development team is pleased to announce the release of Coq
8.7.0, available at:

https://coq.inria.fr/coq-87

Source, Windows and OS X packages are available at:

https://github.com/coq/coq/releases/tag/V8.7.0

This release includes:

- 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.

- New tactics:
  Variants of tactics supporting existential variables eassert, eenough,
etc. by Hugo Herbelin;
  Tactics extensionality in H and inversion_sigma by Jason Gross;
  specialize with accepting partial bindings by Pierre Courtieu.

- Cumulative Polymorphic Inductive Types, allowing cumulativity of
universes to go through applied inductive types, by Amin Timany and
Matthieu Sozeau.

- The SSReflect plugin by Georges Gonthier, Assia Mahboubi and Enrico
Tassi was integrated (with its documentation in the reference manual) by
Maxime Dénès, Assia Mahboubi and Enrico Tassi.

- The coq_makefile tool was completely redesigned by Enrico Tassi to
improve its maintainability and the extensibility of generated
Makefiles, and to make _CoqProject files more palatable to IDEs.

A lot of other changes are described in the CHANGES file.

This 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.
