Python 0.5.4

Features

• A new Tree.is_root method avoids the need to to search the potentially
  large list of Tree.roots (@hyanwong, #2669, #2620)

• The TreeSequence object now has the attributes min_time and max_time,
  which are the minimum and maximum among the node times and mutation times,
  respectively. (@szhan, #2612, #2271)

• The draw_svg methods now have a max_num_trees parameter to truncate
  the total number of trees shown, giving a readable display for tree
  sequences with many trees (@hyanwong, #2652)

• The draw_svg methods now accept a canvas_size parameter to allow
  extra room on the canvas e.g. for long labels or repositioned graphical
  elements (@hyanwong, #2646, #2645)

• The Tree object now has the method siblings to get
  the siblings of a node. It returns an empty tuple if the node
  has no siblings, is not a node in the tree, is the virtual root,
  or is an isolated non-sample node.

• The msprime.RateMap class has been ported into tskit: functionality should
  be identical to the version in msprime, apart from minor changes in the formatting
  of tabular text output (@hyanwong, @jeromekelleher, #2678)

• Tskit now supports and has wheels for Python 3.11. This Python version has a significant performance boost. (@benjeffery , #2624 , #2248 )

Breaking Changes

• the filter_populations, filter_individuals, and filter_sites
  parameters to simplify previously defaulted to True but now default
  to None, which is treated as True. Previously, passing None
  would result in an error. (@hyanwong, #2609, #2608)
