  8. - Add `Select Hole` menu action to quickly select the edges of any hole touching a selected vertex.
  9. - Add a preference to disable "Precise Element Selection."  When disabled edge and vertex modes will always select an edge or vertex no matter how far from the element they are.

  15. - Add Generate UV2 toolbar entry when "Disable Auto UV2 Generation" is enabled.
  16. - Add a delegate in `pb_EditorUtility` to notify subscribers when a new pb_Object has been initialized.
  17. - New API example `Tools > ProBuilder > API Examples > Log Callbacks Window` demonstrates hooking into various editor delegates.
  18. - Adds an experimental new option to store Mesh objects as Assets in the project so as not to clutter the Unity scene file. Use with a prefab for maximum scene lean-ness.  Enable this feature in Preferences/ProBuilder/Experimental/Meshes Are Assets.
  19. - Add support for local/common toggles in Edge Debug mode.
  20. - Add `Select Holes` action to editor toolbar (selects all connected open edge paths).

  28. ## Bug Fixes
  29.  
  30. - Fix some instances where modifying a mesh would result in NaN warnings.
  31. - Fix icosphere audio example scene in ProBuilder Basic.
  32. - Add `Center Pivot` action to menu.
  33. - Bypass sRGB sampling for icons, fixing dark appearance in pro skin.
  34. - Fix regression where switching between icon mode and text mode in toolbar would sometimes not immediately reload the toolbar.
  35. - Fix an issue where meshes would be discarded and rebuilt on every instance id change, which Unity does a lot.  The result of constant mesh rebuilds being invalidating the lightmap, making getting a decent bake very difficult.
  36. - Ignore API examples in any build target that hasn't been tested (which is all of them save for standalones).
  37. - Fix edge extrusion leaving black geometry when extrusion fails.
  38. - Add extrude settings button to edge extrude toolbar item.
  39. - Add a single context-sensitive Extrude shortcut so that super+e works properly in both edge & face modes.

  41. - Fix UV3/4 assignment and getter functions reading out of bounds channel index.
  42. - Fix Delete key notification not showing.

  56. - Fix bug where subdividing a face with an adjacent concave n-gon would break the adjacent face.
  57. - When generating the menu item text for shortcuts always use lower case, since Mac doesn't recognize upper case as shortcuts.  Fixes an issue with shortcuts not working on OSX.
  58. - Support cases where texture groups on pb_Object aren't in linear order.
  59. - Clear debug lines when a selected object is deleted.
  60. - Fix bug where `Detach Faces` to submesh would incorrectly split all the detached selection vertices.
  61. - Put UV Editor in namespace, preventing errors where common function names would be confused with other assets.
  62. - In `pbUndo` use each individual object vertex count when deciding whether to diff or store object state for undo.  Fixes hang when performing actions with small selections on large objects.
  63. - Lower UV toolbar buttons by 1px when not using the Command GUIStyle since Button style adds 1px padding.
