This Lemur project release is for Indri 5.11, Galago 3.10 and RankLib-2.7.
Applications compiled with the Indri API require the following libraries:
z, iberty, pthread, and m on linux.
Applications built in Visual Studio require the additional library wsock32.lib.
The java jar files were built with Java 8 (jdk 1.8.0). The java UIs require Java 8.
We have tested using GCC 4.4.7 (CentOS 6.7 linux), 4.8.4 (Ubuntu 14.04 and 16.04
linux), 4.2.1 (OS/X 10.11.3), and Visual Studio 2012 (Windows 7, WIN32 and x86_64).
Note that OS/X Yosemite (10.10) is not supported at this time.

Galago #bm25f operations.
o BUG# 276 Add support for TSV query formats for XFoldLearner in Galago.
o BUG# 279 Use StringBuffer to load saved models in RankLib. This greatly
speeds the loading of large sized models.
o BUG# 282 Correctly initialize min/max arrays in RankLib linear normalizer.
o BUG# 283 Ensure RankLib sparse data representations are used if selected,
when doing cross fold validation.
Non-Ticket Bug Fixes
o Fixed JSON parsing error in Galago parameters.
o Fixed out of memory error in string parsing within Galago JSONParser.
o Ensure optimization steps in Galago CoordinateAscent learner remain within
upper and lower defined limits.
o Fixes to Galago #prms2, #sdm and #wsdm operators.
