Please make sure you're downloading from a nearby mirror site, not from www.apache.org.
We suggest downloading the current stable release.
The 1.0.x series is the current stable release line, it supercedes 0.98.x and 0.94.x (the 0.98.x and 0.94.x lines are still seeing a monthly cadence of bug fix releases for those who are not easily able to update). Note that 0.96 was EOL'd September 1st, 2014. Use 1.0.x instead.
For older versions, check the apache archive.
