I’ve just made another update available – 11.0.28:

Fixed: Issue with StringReplace could cause unresponsiveness
Fixed: SMTPSendMail: some email clients not deciphering attachment filenames

Apologies for two updates so soon after release. Doesn’t seem to matter what we do something crops up after release. We do need to work on improving testing in the future, but I hope our ability to release fixes quickly makes up for the small issues encountered. I do believe in releasing small fixes often rather than rolling them all up into large less frequent updates. You can always skip an update if it doesn’t affect you. Thanks for your understanding.
