Translations:Compression/6/en

On or about 2004-02-20 the $1 table and $2 table were changed to allow some articles in the history table to be compressed. Old entries marked with old_flags="gzip" have their old_text compressed with zlib's deflate algorithm, with no header bytes. PHP's gzinflate will accept this text plainly; in Perl etc set the window size to -MAX_WSIZE to disable the header bytes.
