[Haskell-cafe] ANNOUNCE: stringsearch 0.3.1, fast searching, splitting and replacing of ByteStrings

Changes vs. 0.3.0: - fixed a space leak in the splitting of lazy ByteStrings Changes of the 0.3 series vs. 0.2.*: - improved performance of the searching functions - new functionality: - breaking of ByteStrings at the first occurrence of a substring - splitting a ByteString at each occurrence of a substring - replacing all occurrences of a substring with another string Where bytestring provides the same functionality (Data.ByteString.breakSubstring, Data.ByteString.findSubstrings), the implementations in stringsearch are typically much faster. By default, stringsearch uses an enhanced Boyer-Moore algorithm to locate a pattern, but it also provides other algorithms which may be better in special cases (Knuth-Morris-Pratt; DFA).
