WithSecure Email and Security 16.00 Hotfix #01 for WebConsole is released

We are pleased to announce the release of Hotfix #01, which upgrades the WebConsole to use Vue.js 3. This update is crucial as support for the Vue.js 2 framework has ended, and it addresses potential vulnerabilities that could be discovered in the now unsupported Vue.js 2 framework.

Please ensure your systems are updated to benefit from the enhanced security and performance improvements provided by Vue.js 3.

Setup is now verifying ACS readiness before upgrade. See page Changes in support on Microsoft Windows – Minimum patch level for additional details.
