If you ever want to check whether a new version of TouchPod or Sakura has come out, just go to the
Chinese GBalpha site. The updates will show up on that site before they do at Handheld Sources.
When you're there, look at the "GBalpha Latest Updates" (GBalpha ????) section, highlighted
here.
In the screenshot above, the top link says:

Click it, and you'll see
this page with the download link highlighted.
At the time of this writing, the latest versions of Sakura and TouchPod are 1.45X 3rd Edition (M19) and 4.7dX (M61), respectively.
I always have the "M" version numbers posted as well. Just keep refreshing the
front page of the Chinese GBalpha site until you see M3 Sakura (M20) or whatever the next version number you're waiting for in the
"Latest Updates" section.
