0.4.5

Fixed:

• Fix determining base ring in from_pyflatsurf when importing surfaces from pyflatsurf.
• Include orbit closure module in documentation at https://flatsurf.github.io/sage-flatsurf.

Performance:

• Improved performance of erasing marked points by Delaunay triangulating first.

0.4.4

Changed:

• Got rid of the FlowDecomposition wrapper in gl2r_orbit_closure.py.

Performance:

• Improved performance of rank computations when computing orbit closures by
  using a faster algorithm for residue fields, see
  https://trac.sagemath.org/ticket/33273.

0.4.3

Added:

• Added another example of an explicit orbit closure computation to the documentation.
• Added better error messages when an optional dependency is not installed,
  pointing out how this dependency could be satisfied.

Changed:

• The copy parameter of Surface_list.__init__() and
  __Surface_dict.__init__() now defaults to surface.is_mutable(). Before
  the default was True. However, in principle this should not break any
  existing code but only change the runtime slightly in some cases.

• The mutable parameter of Surface_list.__init__() and
  Surface_dict.__init__() now defaults to True. Before its default was
  False in many cases. This change might break some existing code. If it
  does, one needs to either explicitly set mutable=False in this invocation or
  call surface.set_immutable().

Removed:

• Removed the unused/ directory which held a collection of unused code that was moved there in 2016.

Fixed:

• Fixed some issues in documentation of Surface classes and simplified some of their implementation.

• Fixed typos that lead to runtime errors in rare cases.

Performance:

• Improved performance of polygon constructions such as triangle(26, 48, 75).

0.4.2

Fixed:

• Adapted to type changes in pyflatsurf 3.7.0.

0.4.1

Performance:

• Speed up kernel and rank computations when computing orbit closures.
