Steve Rowe commented on LUCENE-6993:
------------------------------------

I think you're right, Mike, I don't see any default word break rule modifications in that
list between versions 6.3 and 8.0.

The test data is here: http://www.unicode.org/Public/8.0.0/ucd/auxiliary/WordBreakTest.txt

Here's the full TODO item from LUCENE-5357 (after {{s/6.3/8.0/g}} and {{s/6.1/6.3/g}}):

* Test the new scanners against the Unicode 8.0 word break test data
** -Update {{generateJavaUnicodeWordBreakTest.pl}} to handle above-BMP characters in the Unicode
character database's {{ucd/auxiliary/WordBreakTest.txt}} (previous Unicode versions included
only BMP characters in that file).- (one time operation, already done.)
** Using {{generateJavaUnicodeWordBreakTest.pl}}, generate {{WordBreakTestUnicode_8_0_0.java}}
under {{modules/analysis/common/src/test/org/apache/lucene/analysis/core/}}.
** Update {{TestStandardAnalyzer.java}} and {{TestUAX29URLEmailTokenizer.java}} to invoke
{{WordBreakTestUnicode_8_0_0}} rather than {{WordBreakTestUnicode_6_3_0}}.
** Remove {{WordBreakTestUnicode_6_3_0.java}}.

> We did this once before in LUCENE-5357, but it might be time to update the list of TLDs
again. Comparing our old list with a new list indicates 800+ new domains, so it would be nice
to include them.
> Also the JFlex tokenizer grammars should be upgraded to support Unicode 8.0.
