+25/08/2016 - refactoring of algC and complex in ssrnum -
+	upcomming version 1.7
 	* ssrnum's interface numClosedFieldType factors some theory from
 	  both complex and algC. Because of that Re, Im, 'i, conjC, n.-root
 	  and sqrtC are not specialized to algC anymore. In case of
 	  ambiguity, they should be instanciated with algC using typing
-	  constraints. Moreoever some lemmas from the theory like conjCK
-	  have an extra nonmaximal implicit argument (C :
-	  numClosedFieldType) which could break some proofs. Additionally,
-	  ad-hoc constructions from complex.v like -*+ or complex.Re are now
-	  deprecated and one should rely solely on the ssrnum interface. The
-	  next revision might definietly hide those constructions under a
-	  module.

-## TRANSITION FROM 1.5 to 1.6
-
-The change of logical/physical paths implied by the reorganization of the
-library causes an incompatibility for users of previous version of the
-Mathematical Components library. For instance the command line
-
-          Require Ssreflect.ssreflect.
-
-does not work anymore.  We propose a replacement schema for such
-command lines that is compatible with both versions 8.4 and 8.5 of
-Coq, namely replacing the previous line with:
-
-          Require Import mathcomp.ssreflect.ssreflect.
-
-          From mathcomp Require Import ssrfun ssrbool ...
-
-The first line loads the ssreflect plugin using its full path.
-Then all other files are loaded from the mathcomp name space.
-The component part (like ssreflect or algebra) is omitted.  All theory files in
-the library follow this schema.
-Note that the From directive has effect only in Coq 8.5. Coq 8.4 ignores it
-and searches for files in all known paths: hence beware of the
-possible name collisions.
