[GAP Forum] RCWA <-> GAP 4.4.6, a short notification

[Stefan Kohl]

Dear Forum,

This message is only relevant for those of you who use the RCWA package:

With the recent update from GAP 4.4.5 to GAP 4.4.6, some code which was
formerly misplaced in RCWA has been moved to the main GAP library.

Former versions of RCWA (<= 1.2.1) still contain that code, and trying
to load them in GAP 4.4.6 (or later) will yield an error message,
since the respective variables

     PadicValuation
     EpimorphismFromFreeGroup
     Float
     IsFloat

are now already defined in the library.

The remedy is to update to the recent version 1.2.2 of RCWA of
September 2, which does no longer contain the code which has been moved
into the library.

Apologies for any inconveniences,

     Stefan Kohl
