v0.4.6

Singular v0.4.6

Diff since v0.4.5

Summary of changes

The main change in this release is that it enables several Singular extensions which were not available before. Specifically, these are now enabled (if you need others, let us know)

• gfanlib
• syzextra
• customstd
• interval
• subsets
• loctriv
• gitfan
• freealgebra

Closed issues:

• Libraries are missing, e.g. dmodideal.lib (#378)

Merged pull requests:

• tests: remove vestigial "..." at the end of testset descriptions (#375) (@rfourquet)
• correct symbols(::PolyRing) and do away with singular's native printing (#376) (@tthsqe12)
• some developer documentation (#377) (@tthsqe12)
• bump singular version (#380) (@tthsqe12)
• Bump version (#381) (@thofma)

v0.4.5

Singular v0.4.5

Diff since v0.4.4

Summary of changes

• Singular.jl should no longer crash on the new rings that Singular and its
  libraries can create, or at least it should crash in far fewer cases. At a lower
  level, this means that we have the internal function create_ring_from_singular_ring
  for turning a libSingular.ring_ptr into a bona fide Ring.
• Singular's algebraic extensions of QQ and Fp can now be constructed via the
  function AlgebraicFieldExtension. This function takes a univariate FunctionField
  and a minimal polynomial in the function field to create the algebraic extension.
• Various small bugs have been fixed.

Closed issues:

• isnegative in src/number/n_Zp.jl calls isless, which is not defined (#50)
• Radical of an ideal (#101)
• Provide an up to date version of the documentation (#125)
• double definition (#308)
