Software Release Updates
WatchGuard is pleased to announce the availability of a significant new maintenance update, Fireware 11.10.4 and WSM 11.10.4. The new releases provide many key bug fixes, some new enhancements, and support of latest operating systems. Key highlights include:

• SMTP proxy can be configured to block executable files within compressed archives, which can help prevent the spread of malware and ransomware.
• Mobile VPN with SSL client now supports Mac OS X 10.11 (El Capitan)
• XTMv support for VMware ESXi 6.0
