24/11/2015 - major reorganization of the archive - version 1.6
* Files split into subdirectories: ssreflect, algebra, fingroup,
solvable, field and character. In this way the user can decide
to compile only the subset of the Mathematical Components library
that is relevant to her.
* The archive is now open and based on git. Public mirror at:
https://github.com/math-comp/math-comp
* Sources of the reference manual of the Ssreflect tactic language are
also open and available at:
https://github.com/math-comp/ssr-manual
Pull requests improving the documentation are welcome.
* Renamings or replacements:
conjC_closed -> cfConjC_closed
class_transr -> class_eqP
cfclass_transl -> cfclass_transr
nontrivial_ideal -> proper_ideal
zchar_orthonormalP -> vchar_orthonormalP
* Definitions that changed:
seq_sub
* Statements that changed:
orbit_in_transl, orbit_sym, orbit_trans, orbit_transl, orbit_transr,
cfAut_char, cfConjC_char, invg_lcosets, lcoset_transl,
lcoset_transr, rcoset_transl, rcoset_transr, mem2_last,
bind_unless, unless_contra, all_and2, all_and3, all_and4, all_and5,
ltr0_neq0, ltr_prod, Zisometry_of_iso
* New definitions:
adhoc_seq_sub_choiceMixin, adhoc_seq_sub_[choice|fin]Type
* New theorems:
orbit_in_eqP, cards_draws, cfAut_lin_char, cfConjC_lin_char,
extend_cfConjC_subset, isometry_of_free, cfAutK, cfAutVK,
lcoset_eqP, rcoset_eqP, class_eqP, gFsub_trans, gFnorms,
gFchar_trans, gFnormal_trans, gFnorm_trans, mem2_seq1,
dvdn_fact, prime_above, subKr, subrI, subIr, subr0_eq,
divrI, divIr, divKr, divfI, divIf, divKf, impliesP, impliesPn,
unlessL, unlessR, unless_sym, unlessP (coercion), classicW,
ltr_prod_nat
* New notation: "\unless C, P"
12/03/2014 - split the archive in SSReflect and MathComp - version 1.5
* With this release "ssreflect" has been split into two packages.
The Ssreflect one contains the proof language (plugin for Coq) and a
small set of core theory libraries about boolean, natural numbers,
sequences, decidable equality and finite types. The Mathematical
Components one contains advanced theory files covering a wider
spectrum of mathematics.
* With respect to version 1.4 the proof language got a few new
features related to forward reasoning and some bugfixes. The
Mathematical Components library features 16 new theory files and in
particular: some field and Galois theory, advanced character theory
and a construction of algebraic numbers.
05/09/2012 - ssreflect - version 1.4
* With this release the plugin code received many bug fixes and the
existing libraries relevant updates. This release also includes
some new libraries on the following topics: rational numbers,
divisibility of integers, F-algebras, finite dimensional field
extensions and Euclidean division for polynomials over a ring.
* The release includes a major code refactoring of the plugin for Coq
8.4. In particular a documented ML API to access the pattern matching
facilities of Ssreflect from third party plugins has been introduced.
14/03/2011 - ssreflect - version 1.3
* The tactic language has been extended with several new features,
inspired by the five years of intensive use in our project. However we
have kept the core of the language unchanged; the new library compiles
with Ssreflect 1.2. Users of a Coq 8.2 toplevel statically linked
with Ssreflect 1.2 need to comment the Declare ML Module "ssreflect"
line in ssreflect.v to properly compile the 1.3 library. We will
continue supporting new releases of Coq in due course.
* The new library adds general linear algebra (matrix rank, subspaces)
and all of the advanced finite group that was developed in the course
of completing the Local Analysis part of the Odd Order Theorem,
starting from the Sylow and Hall theorems and including full structure
theorems for abelian, extremal and extraspecial groups, and general
(modular) linear representation theory.
14/08/2009 - ssreflect - version 1.2
* No change log
18/03/2008 - ssreflect - version 1.1
* First public release
