Linux Mint 15 “Olivia” was released last night.
I woke up this morning to find the release news on Distrowatch. I haven’t tried it yet. It’s planned for this weekend however.
At the moment I was writing this post, the Linux Mint servers were still very busy with loads of traffic. Consequently, download speed has become very slow. I had provided the ISO files for download previously. I’ve removed them now. Please download from the Linux Mint mirrors.
