Version 3.2.1 of Grep Console is out, fixing the following bugs:
Performance issues with regular expression matching. Changes in the matching code lead to serious performance problems for some users. Some modifications in the matching function should hopefully fix that. Thanks to Michaël Clavier and “Jordi” for reporting this bug.
Unmatched lines are no longer set to the default style. Previously, lines that did not match any expressions were nevertheless set to the default font style, overriding font colours set in the console preferences. Thanks to Angel Ezquerra for reporting this bug.
