Undo has been greatly improved by making many functions that use to skip a backup now backup.
A new type of node called NoOutputGroup has been added. NoOutputGroup behaves the same as a standard VRML Group node except when a file is output a NoOutputGroup node and any of its children are not output. This allows the user to put nodes in a smls file that are only there for the purpose of editing and so are not intended to end up in the output file.
A step field has been added to the FreezeTime control panel. It causes the time field to increment and decrement in amounts of the value specified by step.
Miranda tried to add ROUTEs to the Seamless node's transform fields (scale, rotation and translation fields are transform fields). This worked fine in the 3d window but caused errors in the output wrl. This is something perfectly logical to do and so has been fixed for 2.079 so that when output all works fine when this is done. Many thanks to Miranda for focusing my attention on this issue.
Back to 2.080 update:
I noticed the eyes in my petra.smls file when output as a wrl the eyes looked wrong. I found out this was because they were no longer in the correct location and the reason for this was because the translation values for all the parts were being rounded down to only 2 digits right of the decimal point same as what is done for the multiple colour values in the output IndexedFaceSet. This was intentional for the multiple colour values when output but for other fields such as the translation fields this was unintentional and so has now been fixed for 2.080. Hopefully this was not a noticeable problem for most avatars but for petra's eyes it was.
