In the interest of clarity, I am providing a list of the patches that I believe should be applied to the SVN HEAD codebase to facilitate the release of Lucene.Net 2.3.1. The resulting codebase currently has 1 test class with failing unit tests: Lucene.Net.Search.Spans.TestSpans. The failing tests are TestSpanNearOrdered0[2-5](); all appear to suffer from the same issue. The patches that are outstanding (diverge from the current SVN HEAD) are: LUCENENET-135 SupportClass.patch LUCENENET-143 TestStressIndexing2.patch, FieldsReader.patch LUCENENET-145 DocumentsWriter.patch LUCENENET-146 SegmentTermPositionVector.patch LUCENENET-152 SegmentInfos.patch, FSDirectory.patch LUCENENET-154 TestIndexWriterLockRelease.patch LUCENENET-155 SetUp.patch LUCENENET-157 SegmentMerger.patch -Doug
