Version: 3.2013a

Release date: July 28, 2013

Build up with Sphider: v.1.3.5


Honor:

This version of Sphider-plus is dedicated to Anton Cygankov. For all the month, he followed the development with an ongoing testing. Verifying especially the index procedure with thousands of URLs and reviewing all the bugs, I intermediately implemented. Thank you very much for this big effort. I wouldn't be able to get up to the current status of development, without your enormous support.
It took several months to come up with the v.3 release, but together with the SQLi support, it seems to be a reasonable step into the future of this search engine.
