11. NUTCH-495 - Unnecessary delays in Fetcher2 (dogacan)
+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.
+
Release 0.9 - 2007-04-02
1. Changed log4j confiquration to log to stdout on commandline
