======================= Lucene 3.5.0 =======================
Changes in backwards compatibility policy
* LUCENE-3390: The first approach in Lucene 3.4.0 for missing values
support for sorting had a design problem that made the missing value
be populated directly into the FieldCache arrays during sorting,
leading to concurrency issues. To fix this behaviour, the method
signatures had to be changed:
- FieldCache.getUnValuedDocs() returns the interface Bits instead DocIdSet
- FieldComparator.setMissingValue() was removed and added to
constructor
As this is expert API, most code will not be affected.

QueryWrapperFilter and similar classes to get a top-level DocIdSet.

* LUCENE-3390: Corrected handling of missing values when two parallel searches
using different missing values for sorting: the missing value was populated
directly into the FieldCache arrays during sorting, leading to concurrency
issues. (Uwe Schindler, Doron Cohen, Mike McCandless)
