0.9.1 (2026-02-11)

• [NEW FEATURE] The mutreach_leaves argument to mst_euclid
  controls the postprocessing of tree leaves.

• [BACKWARD INCOMPATIBILITY] The definition of the mutual reachability
  distance has changed (for notational prudence). Unlike in
  Campello et al.'s 2013 paper, now the core distance is the distance
  to the M-th nearest neighbour, not the (M-1)-th one (not including self).

• [BACKWARD INCOMPATIBILITY] The mutreach_adj argument to mst_euclid
  was removed. Instead, the mutreach_ties argument is now available.
  It defaults to "dist_min" for (rough) compatibility with other packages.

• [BUGFIX] #3: SIGSEGV on duplicated inputs in mst_euclid
  with algorithm="brute" was fixed.
