On 24 December 2013, I posted version 2.1 of the Offo hyphenation patterns for FOP. These patterns were derived from the most recent TeX patterns at svn://tug.org/texhyphen/trunk/.
On 21 January 2010 I replaced the file offo-hyphenation-utf8.zip, which contains the source patterns. It was reported to me that the earlier file did not actually contain the source patterns but the compiled patterns. This has now been corrected.
