C API 1.1.0

Features

• Add num_children to tsk_tree_t an array which contains counts of the number of child
  nodes of each node in the tree. (@GertjanBisschop, #2274, #2316)

• Add edge to tsk_tree_t an array which contains the edge_id of the edge encoding
  the relationship between the child node and its parent for each (child) node in the tree.

Changes

• Reduce the maximum number of rows in a table by 1. This removes edge cases so that a tsk_id_t can be
  used to count the number of rows. (@benjeffery, #2336, #2337)

• Samples are now copied by tsk_variant_restricted_copy. (@benjeffery, #2400, #2401)
