2.4.5 is intended to be the final bugfix release in the 2.4 series, for those who haven't yet moved on to 2.5. See the full list of changes.
Source code is available in the usual place. Compiled Windows packages are not available yet, but should hopefully arrive shortly; we'll post again here when they turn up.
