Thu Sep 27 18:00:00 CEST 2007 Singular-3-0-3-1
Changes with respect to 3-0-3:

- SAGE patches (for building libsingular) integrated
- flex/bison generated files integrated: these files will only
  be regenerated if removed;
  a normal build will no longer need bison and flex, but configure still
  tests for them.
- gftables changed to tables based on Conway polynomials
  (see factory/ConwayList.txt) and more tables created
  (for all fields of char p < 255 with < 2^16 elements)
- multivariate GCD (in char 0, no extension) improved
  by a modular method: selected by On(SW_USE_CHINREM_GCD), on by default
- modgen has no longer a builtin path:
  change SINGULARROOT in the generated Makefile if you dislike the default

----------------------------------------------------------
Tue Oct 16 18:58:18 CEST 2007 Singular-3-0-3-2
Changes with respect to 3-0-3-1:

- bison generated file integrated also for factory
- modgen: target clean will no longer remove bison generated files
          fixes wrt. %return
- gcd in algebraic extensions: remove content wrt. K(alpha), not only wrt. K
- EZGCD: special case is handled by CHINREM_GCD
- heuristic for gcd in char 0: 1) EZGCD 2) CHINREM_GCD 3) Prem
- NTL: update to version 5.4.1
- doc/general.doc: description of algorithms updated
- omalloc: areas may overlap: use memmove instead of memcpy
---------------------------------------------------------

Wed Oct 31 18:57:21 CET 2007 Singular-3-0-4-beta
Changes with respect to 3-0-3-2
- more modgen fixes
- Weyl, Exterior, findimAlgebra, nc_algebra do not change the current ring but
  return the new structure
- ncalgebra is now depreciated, use the new command nc_algebra
- libraries changes to use nc_algebra

Fri Nov  2 14:31:22 CET 2007 Singular-3-0-4-beta
more Changes with respect to 3-0-3-2
- use of boost and std::vector can be changed via configure
  (--without-Boost, --with-stdvec)

Tue Nov  6 16:02:29 CET 2007 Singular-3-0-4-beta
more Changes with respect to 3-0-3-2
- new system("SingularLib"): return SINGULAR_PATH after evaluation
- standard.lib:weightKB improved
- highest corner and weights fixed (was wrong in ring with ordering Ws/ws)

Tue Nov 13 18:26:32 CET 2007 Singular-3-0-4-beta
- surfex.lib: find path to surfex via system("Singular"),
              if this fails, try also all directorories in system("SingularLib")
- timer: find clock ticks:
    - try HZ (traditional)
    - try CLK_TCK (POSIX-1)
    - try sysconf(_SC_CLK_TCK) (POSIX-2)
---------------------------------------------------------
Tue Nov 27 12:16:36 CET 2007 Singular-3-0-4-1
Changes with respect to 3-0-4
- dmod.lib: fixes wrt. nc_algebra and documentation
- allow assignments like: def l=1,2,3;

---------------------------------------------------------
Tue Dec 18 14:12:46 MET 2007
Changes with respect to 3-0-4-1
- could not include bits/sigcontext.h and asm/sigcontext.h:
  include signal.h and hope for the best
- glibc 2.6/2.7 does not have a dynamic fstat - use our own from
  Singular/misc.cc: singular_fstat
- fixed LIB/involut.lib: problems with ring change : nc_algebra

---------------------------------------------------------
Jan 01 2008
more Changes with respect to 3-0-4-1
- adaption of the default modules to GLIBC changes
  (does not apply to static versions):
  Unfortunately, the GLIBC developpers decided to omit some functions from
  the dynamic version of libc (starting from GLIBC 2.4/2.5).
  Some of these function are now provided in the Singular executable
  (singular_fstat for fstat), for others we have to link with
  libc_nonshared  (for stack_chk_fail*)
  (maybe, -fno-stack-protector -fno-stack-protector-all
  could also fix this...but some libraries could use it also..).
  Currently, this applies to mpsr.so, dbmsr.so

- conversion of polynomials Singular <--> factory optimized: uses sbuckets
---------------------------------------------------------
Tue Jan 22 10:40:39 CET 2008
more Changes with respect to 3-0-4-1
- sqrFree moved from libfac to factory
- new command sqrfree
---------------------------------------------------------
Mon Feb  4 14:32:43 MET 2008
more Changes with respect to 3-0-4-1
- rSetHdl test now if the ring has an entry for module comp:
  to many routines rely on that.
  If the ring has not, it is changed: see kernel/ring.cc:rAssure_HasComp
