Changes 4.50:
A new version of LU-factorization routines were added.
Currently this version provides the same functionality as the
old one, however, the new version allows further improving.

Old routines for FHV-factorization used to update the basis
factorization were replaced by a new version conforming to the
new version of LU-factorization.

Some clarifications about using the name index routines were
added.

Some typos were corrected in the MathProg language reference.

A serious bug (out-of-range indexing error) was *tentatively*
fixed in the routine glp_relax4. Unfortunatly, this bug is
inherited from the original Fortran version of the RELAX-IV
code (for details please see ChangeLog), and since the code is
very intricate, the bug is still under investigation.
Changes 1.42.1:
* Update Vietnamese translation.
* Update Croatian translation.
* Consistently strip path and/or libtool "lt-" prefix from any instance
  of $program derived from --help or --version.
Updated math/glpk to 4.50; converters/help2man to 1.42.1
Changes 2.7.1:
This is a bugfix release.

Bug fixes:

* Fixed a bug in the new ECC code. The ecc_j_to_a function
  called GMP:s mpn_mul_n (via ecc_modp_mul) with overlapping
  input and output arguments, which is not supported.

* The assembly files for SHA1, SHA256 and AES depend on ARMv6
  instructions, breaking nettle-2.7 for pre-v6 ARM processors.
  The configure script now enables those assembly files only
  when building for ARMv6 or later.

* Use a more portable C expression for rotations. The
  previous version used the following "standard" expression
  for 32-bit rotation:

    (x << n) | (x >> (32 - n))

  But this gives undefined behavior (according to the C
  specification) for n = 0. The rotate expression is replaced
  by the more portable:

    (x << n) | (x >> ((-n)&31))

  This change affects only CAST128, which uses non-constant
  rotation counts. Unfortunately, the new expression is poorly
  optimized by released versions of gcc, making CAST128 a bit
  slower. This is being fixed by the gcc hackers, see
  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57157.

The following problems have been reported, but are *not* fixed
in this release:

* ARM assembly files use instruction syntax which is not
  supported by all assemblers. Workaround: Use a current
  version of GNU as, or configure with --disable-assembler.

* Configuring with --disable-static doesn't work on windows.

The libraries are intended to be binary compatible with
nettle-2.2 and later. The shared library names are
libnettle.so.4.7 and libhogweed.so.2.5, with sonames still
libnettle.so.4 and libhogweed.so.2.
Updated security/nettle to 2.7.1
