2. NUTCH-443 - Allow parsers to return multiple Parse objects.
(Dogacan Guney et al, via ab)

(Eelco Lempsink via ab)
4. NUTCH-456 - Parse msexcel plugin speedup (Heiko Dietze via siren)
5. NUTCH-446 - RobotRulesParser should ignore Crawl-delay values of other

12. NUTCH-443 - allow parsers to return multiple Parse object, this will speed
up the rss parser (dogacan via mattmann). This update is a fix and semantics
change from the original patch for NUTCH-443. The original patch did not tell
the Indexer to read crawl_parse too so that it can pickup sub-urls' fetch
datums. This patch addresses that issue. Now, if Fetcher gets a null content,
instead of pushing an empty content, it filters the null content.
13. NUTCH-485 - Change HtmlParseFilter 's to return ParseResult object instead of
Parse object. (Gal Nitzan via dogacan)

performance and compatibility. This patch introduced a new plugin, feed,
that includes an index filter and a parse plugin for feeds that uses ROME.

however, this patch does not explicitly remove parse-rss. (dogacan, mattmann)
17. NUTCH-471 - Fix synchronization in NutchBean creation.
(Enis Soztutar via dogacan)
18. Upgrade to Lucene 2.2.0 and Hadoop 0.12.3. (ab)

when trying to rerun dedup on a segment. (Vishal Shah via dogacan)
35. NUTCH-514 - Indexer should only index pages with fetch status SUCCESS.
(dogacan) Note: There is a bigger problem, i.e how to deal
with redirected pages, and this issue can be considered as a band-aid
for the time being. See NUTCH-273 and NUTCH-353 for more details.
36. NUTCH-533 - LinkDbMerger: url normalized is not updated in the key and
inlinks list. (Emmanuel Joke via dogacan)

* can be partially migrated using 'mergesegs', however segments will *
* require re-parsing (and consequently re-indexing). *
