This release fixes a check for TCP RST flags to prevent sending resets to reset packets with inline and active responses, updates hashing for internal storage of rule options for 64bit platforms when checking uniqueness to remove duplicate copies in memory and addresses some small memory leaks from parsing snort.conf. Please note that and later packages are signed with a new PGP key (which is signed with the previous key).
