Coq 8.7

The previous version: Coq 8.7

This version features:

  • 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 to improve its maintainability and the extensibility of generated Makefiles, and to make _CoqProject files more palatable to IDEs by Enrico Tassi.

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.
