Dev:Ref/Release Notes/2.59

Blender 2.59 update log

This is mostly a bug fix release with 140 fixes since 2.58a. Additions include improved keymap editing, 3D mouse support, some new addons and Node UI improvements.

Prominent features (the cool stuff)

3D Mouse support "NDOF"

Blender is now built with support for 3D Connexion devices, for more natural control during view navigation and fly mode - r38908

Custom Keymaps

User edited keymaps now no longer override the builtin keymaps entirely, but rather save only the difference and reapply those changes. This means they can stay better in sync when the builtin keymaps change.

Keymaps in blender are now separated so Addons can properly define their own keymaps without them conflicting with user keymaps

See commit log for details - r39084

Ivy Generator (Addon)

This tools adds the ability to "grow" curves over an existing mesh with the option of adding leaves and adjusting many parameters for the final result - r2200

See: http://wiki.blender.org/index.php/Extensions:2.5/Py/Scripts/Curve/Ivy_Gen

Sapling (Addon)

This tree generator creates completely parametrically generated trees from curves - r2119

See: http://wiki.blender.org/index.php/Extensions:2.5/Py/Scripts/Curve/Sapling_Tree

Grease Scatter (Addon)

Grease scatter was used for sintel to place objects around the ally, using grease pencil lines as a guide as to where to scatter objects - r2125

Node editor enhancements

Several enhancements are done related to the node editor/compositor.

• Material passes: Materials have pass-index. This pass-index can be used in the compositor to create mattes. It works the same as object passes.
• Node insert: Nodes that have no connections can be inserted on a noodle. Just move the node over the noodle and release when the noodle turns orange.
• Delete with reconnect: It is possible to delete a node that is connected in the tree, without loosing the connections. The node is deleted, but the links are reconnected as if the node were muted. Select a node and press CTRL-X.
• Noodle curves: Some users like straight noodles, other like curved, in the user preferences the level of the curvation can be changed.
• Node properties: The UI of the side panel and on the node can now be different. See the Color balance node in the side panel.

Additions

• Material passes (like object passes), (See commit log for details) - r38090

• UV Straighten tool - r38598
• Object Align: high quality option for perfect alighment http://www.pasteall.org/pic/show.php?id=15171 - r38511

• Object.closest_point_on_mesh() function - r38449
• bpy.path.basename because "//" prefix breaks os.path.basename - r38528
• Vector.length_squared to use instead of vec.dot(vec) - r39300

Guidelines for SVN > Changelog

Note: Please dont just add items here unless they are included in the svn range listed below. otherwise we cant keep track of whats in.

When moving reports into the changelog...

• include bugfixe numbers [#1234] and svn commits as r1234, these are converted into links later.
  Use this formatting:
  fix [#54321] Some issue fixed - r12345 ... or
  fix: Some issue fixed - r12345 ... or
  Some change made - r12345
• sentences should make sense on their own, not just copy commit log or tracker report's which don't always have a lot to do with the actual fix or are too technical.

Skip...

• maintenance commits (build system, corrected spelling, compiler warnings, doc generator)
• fixes to mistakes in newly added code.
• very minor fixes/slight changes in behavior (change log should be noteworthy)
