<h2>
<u>Plans for future developments</u></h2>
The plan for the next release after 0.8.45 is to from alpha (all 0.8 series
version) to beta for the next release, at this point will bump the version
number up to 0.9.0 and all subsequent 0.9 releases will be beta, up till
the release of 1.0. The current goal is to move to beta in early summer,
with 1.0 in late summer, with SIGGRAPH being a possibility.
Now we have reached the beta phase (0.9.x) of OpenScenegGraph project,
and are now working towards the full 1.0 release, with a likely
release date in fall 2002.
