The 30th era of X-Men (named Shadows of Tomorrow by Marvel) is currently ongoing. How long it will last is not yet known. It takes some time for an era to complete (these days, usually around a year or two), so it will likely be some time before the next update to this site.
In the meantime, you can check out the other addition I finally added – a reading order for Ultimate X-Men (that is, the X-Men of the original Ultimate Universe, Earth 1610)! I added this because people often come to this site with some confusion, expecting it to cover that version of the X-Men, which is understandable. So now it does!
I hope this site enriches your X-Men reading experience. These characters and their story have gained a permanent place in my heart, and my greatest hope is that my work here makes it easier for you to have a similar experience, whether it be from reading the entire story or just the part(s) you choose.
