5 releases include changes to Websites.
Core can now back up and restore your hosting package, and you choose what goes in. October also brought wildcard SSL certificates, a welcome tour for Core and a long list of fixes.
August fixed MySQL user management and the web statistics sign-in, and made deleting a website tidier.
June was about telling you what happened. When something fails, the Panel now says so in plain words instead of leaving a page blank.
In May the Panel started showing when an action is working, and notices now stay until you close them. Dedicated IPs, SSL certificates and scheduled tasks got a round of fixes.
The Panel moved to a new interface in April, with light and dark themes and search in the header. We also fixed the issues you reported in its first weeks.
