The 3.9.3 release fixes the following issues.
Add customerId parameter to the eTools document source.
Folks willing to use the "web" document source, kindly provided
by Comcepta AG should
contact Comcepta for a private customer key (otherwise the number of queries
per IP is limited and may result in IP-blocking).
Sonatype repository references moved from http to https.
POM now refers to https location for SonaType's release repositories.
Updated foamtree visualization to version 3.2.0.
FoamTree visualization has been updated to the new shiny version,
which is faster and supports
super-large hierarchies (although clustering
will typically produce much more shallow results).
Per-algorithm lexical resources in the DCS.
The DCS now supports per-algorithm resource lookup locations, which in turn allows
configuring the same algorithm with different stop words, etc.
