You probably caught this NOTAM post:
"Version.txt" and "Maintenance Logs" ....
As a part of REFRESH 2019, we are adding a couple of things you might not notice. When you download a scenery folder from RTMM now, inside the /scenery folder of the folder you put into your addon area is a tiny "version.txt" file. You will find it in with the bgl files. As we standardize on location NAMES ... we are getting rid of the "version number" and other misc entries that have been a part of the name. We do this so when you download an update, the folder will be titled something like (example) Misty's Place ... (Not Misty's Place PF20 or Misty's Place Version 4.0 ... just Misty's Place). All you then have to do is delete the old Misty's Place folder and replace it with the new and not have to redirect your Scenery Library to find a new name. But it doing this, you lose the ability to know which version you have. Now you will know. If you go to the /scenery file (where the bgl files reside) you'll find the version.txt. Click on it and the date of the location update and version are always there for you. This is now in every RTMM scenery download.
Also, all of the maintenance logs are now installed on ALL scenery locations. If you click on the REFRESHED DATE link at the top of each locations entry box, that link opens the maintenance log for that scenery location. So if you see there's an update, if you click on the link, you will see what we updated, when it was updated, and who did the update.
With all the changing, we'll have some typos and screwy things happening here and there. We have everything "in place" but now we go after those pesky details. One note for you, on the Maintenance Log ... you do not need to "do" anything if the text is in black. If the text is in RED, you should re-download and re-install the scenery.
