This Lemur project release is for Indri 5.10, Galago 3.9 and RankLib-2.6.

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 6.6 linux), 4.8.4 (Ubuntu 14.04 linux), 
4.2.1 (OS/X), and Visual Studio 2010 and 2012 (Windows 7, WIN32 and x86_64).

Note that OS/X Yosemite (10.10) is not supported at this time.


Bug Fixes
  See https://sourceforge.net/p/lemur/bugs/ for the complete ticket listing.

  o BUG# 273  Galago eval statistical tests have been restored using Apache 
              commons-math3 library.

  o BUG# 270  Identify ZScoreNormalizer in error message when encountering an empty
              ranked list in RankLib.

  o BUG# 269  Add Indri read/write locks to eliminate MemoryIndexvocabularyiterator
              exception when searching with wildcards.

  o BUG# 267  Store RankLib k-fold cross validation models in specified or default
              named directory.  Store k-fold validation names as specified or using
              a default.  Don't bail out if k-fold directory isn't specified by a
              name is (use default).

  o BUG# 266
         265  Get a proper document ID from the WARC-TREC-ID field when indexing
              WARC data with Galago.


Feature Requests
  See https://sourceforge.net/p/lemur/support-requests/ for the complete 
  ticket listing. 

  o FR# 131   Define operatorWrap argument to batch-search.  This defines an outer
              query operator to be used on all queries in a batch query file.  This
              facilitates testing of various operators on a query set without the 
              need to create separate query files that differ only in their outermost
              operation.

  o FR# 128   Add Galago operator help command which prints out a list of all search
              operators, their respective classes and input and output types.

  o FR# 127   Galago eval function uses commandline option --boosting to determine if
              boosted statistical tests are run.  By default, only Sign, T and 
              Randomized stats tests are used.


Contributions
  o Addition of Fielded Sequential Dependence (FSDM) and Mixture of Language Models (MLM)
    retrieval operators, described in their paper:

      N. Zhiltsov, A. Kotov and F. Nikolaev.  "Fielded Sequential Dependence Model for 
        Ad-Hoc Entity Retrieval in the Web fo Data".  (ACM SIGIR, 2015).

    Further development information can be found in the FieldedSDM source repository on 
    github.
