Comment:
make the SIGSEGV statement conditionally, otherwise it may make people think there is generally the risk of SIGSEGV

    * StandardAnalyzer is moved to core and is the default analyzer
    * MatchNoDocsQuery now includes the reason it was created
    * QueryParser can now be told to not pre-split on whitespace
-   * MMapDirectory tries harder to prevent SIGSEGV, but it's still best effort
+   * MMapDirectory tries harder to prevent SIGSEGV if buggy code tries to execute
+     searches after the index was closed, but it's still best effort
+   * MMapDirectory no longer allocates weak references to ease garbage
+     collection
  
  Optimizations
    * Conjunction (MUST, FILTER) queries are faster
