  "message": "Sub filter: eliminate unnecessary buffering.\n\nPreviously, when a buffer was processed by the sub filter, its final bytes\ncould be buffered by the filter even if they don\u0027t match any pattern.\nThis happened because the Boyer-Moore algorithm, employed by the sub filter\nsince b9447fc457b4 (1.9.4), matches the last characters of patterns prior to\nchecking other characters.  If the last character is out of scope, initial\nbytes of a potential match are buffered until the last character is available.\n\nNow, after receiving a flush or recycled buffer, the filter performs\nadditional checks to reduce the number of buffered bytes.  The potential match\nis checked against the initial parts of all patterns.  Non-matching bytes are\nnot buffered.  This improves processing of a chunked response from upstream\nby sending the entire chunks without buffering unless a partial match is found\nat the end of a chunk.\n",
