+24/11/2015 - major reorganization of the archive - version 1.6
+ * Files split into subdirectories: ssreflect, algebra, fingroup,
+ solvable, field and character.
+
+ * The archive is now open and based on git. Public mirror at:
+ https://github.com/math-comp/math-comp
+
+ * Renamings or replacements:
+ conjC_closed -> cfConjC_closed
+ class_transr -> class_eqP
+ cfclass_transl -> cfclass_transr
+ nontrivial_ideal -> proper_ideal
+ zchar_orthonormalP -> vchar_orthonormalP
+
+ * 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 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
