(Note: some bugs were fixed in this area in PCRE + 8.38.) Previously Hyperscan's behaviour was the same as versions of PCRE + before 8.34. +- Improve performance when compiling pattern sets that include a large number + of similar bounded repeat constructs. (github issue #9) + +## [4.0.1] 2015-10-30 +- Minor cleanups to test code. +- CMake and other build system improvements. +- API update: allow `hs_reset_stream()` and `hs_reset_and_copy_stream()` to be + supplied with a NULL scratch pointer if no matches are required. This is in + line with the behaviour of `hs_close_stream()`. +- Disallow bounded repeats with a very large minimum repeat but no maximum, + i.e. {N,} for very large N. +- Reduce compile memory usage in literal set explansion for some large cases. + +## [4.0.0] 2015-10-20 +- Original release of Hyperscan as open-source software.
