I think we could back port all of these.
But many of them are "minor"...

I just need the information, if there is anything else that should go

Here is a list of bugs fixed in 3.x that weren't backported... i didnt
spend a lot of time on these. perhaps its easy to reopen all of them
and set version to 3.0/2.9, and we can discuss on the the list/jira
that way
BUGS:
* LUCENE-2216: OpenBitSet.hashCode returned different hash codes for
sets that only differed by trailing zeros. (Dawid Weiss, yonik)
* LUCENE-2235: Implement missing PerFieldAnalyzerWrapper.getOffsetGap().
(Javier Godoy via Uwe Schindler)
* LUCENE-2249: ParallelMultiSearcher should shut down thread pool on
close. (Martin Traverso via Uwe Schindler)
This seems more serious since it's a resource leak...
* LUCENE-2273: FieldCacheImpl.getCacheEntries() used WeakHashMap
incorrectly and lead to ConcurrentModificationException.
(Uwe Schindler, Robert Muir)
Not sure if this is relevant to 3.0.x/2.9.x?
* LUCENE-2328: Index files fsync tracking moved from
IndexWriter/IndexReader to Directory, and it no longer leaks memory.
(Earwin Burrfoot via Mike McCandless)
The mem leak here is miniscule and it was a big patch so I think we
shouldn't back port.
* LUCENE-2365: IndexWriter.newestSegment (used normally for testing)
is fixed to return null if there are no segments. (Karthick
Sankarachary via Mike McCandless)
* LUCENE-2074(just the subtask): Reduce buffer size of lexer back to
default on reset.
(Ruben Laguna, Shai Erera via Uwe Schindler)
* LUCENE-2496: Don't throw NPE if IndexWriter is opened with CREATE on
a prior (corrupt) index missing its segments_N file. (Mike
McCandless)
* LUCENE-2513: when opening writable IndexReader on a not-current
commit, do not overwrite "future" commits. (Mike McCandless)
We should backport this one -- admittedly a corner case, but, it can
remove commits from your index...
* LUCENE-2533: fix FileSwitchDirectory.listAll to not return dups when
primary& secondary dirs share the same underlying directory.
(Michael McCandless)
* LUCENE-2549: Fix TimeLimitingCollector#TimeExceededException to record
the absolute docid. (Uwe Schindler)
* LUCENE-2580: MultiPhraseQuery throws AIOOBE if number of positions
exceeds number of terms at one position (Jayendra Patil via Mike McCandless)
* LUCENE-2616: FastVectorHighlighter: out of alignment when the first value is
empty in multiValued field (Koji Sekiguchi)
* LUCENE-2272: Fix explain in PayloadNearQuery and also fix scoring
issue (Peter Keegan via Grant Ingersoll)
* LUCENE-2658: Exceptions while processing term vectors enabled for multiple
fields could lead to invalid ArrayIndexOutOfBoundsExceptions.
(Robert Muir, Mike McCandless)
Looks serious...
contrib/CHANGES:
* LUCENE-2035: TokenSources.getTokenStream() does not assign
positionIncrement.
(Christopher Morris via Mark Miller)
* LUCENE-2055 (doc fix only, recommend to use snowball): Deprecated
RussianTokenizer, RussianStemmer, RussianStemFilter,
FrenchStemmer, FrenchStemFilter, DutchStemmer, and DutchStemFilter. For
these Analyzers, SnowballFilter is used instead (for Version> 3.0), as
the previous code did not always implement the Snowball algorithm correctly.
Additionally, for Version> 3.0, the Snowball stopword lists are used by
default. (Robert Muir, Uwe Schindler, Simon Willnauer)
* LUCENE-2278: FastVectorHighlighter: Highlighted term is out of alignment
in multi-valued NOT_ANALYZED field. (Koji Sekiguchi)
* LUCENE-2284: MatchAllDocsQueryNode toString() created an invalid XML tag.
(Frank Wesemann via Robert Muir)
* LUCENE-2277: QueryNodeImpl threw ConcurrentModificationException on
add(List<QueryNode>). (Frank Wesemann via Robert Muir)
* LUCENE-2184: Fixed bug with handling best fit value when the proper
best fit value is
not an indexed field. Note, this change affects the APIs.
(Grant Ingersoll)
* LUCENE-2359: Fix bug in CartesianPolyFilterBuilder related to
handling of behavior around
the 180th meridian (Grant Ingersoll)
* LUCENE-2524: FastVectorHighlighter: use mod for getting colored tag.
(Koji Sekiguchi)
* LUCENE-2653: ThaiWordFilter depends on the JRE having a Thai
dictionary, which is not
always the case. If the dictionary is unavailable, the filter will now throw
UnsupportedOperationException in the constructor. (Robert Muir)
