Hi, this is my first post here, so be gentle

Yesterday I installed LE7.0 on my RPi3 and upgraded it to your #0512 version for RPI2. Since everything worked well, today I upgraded to #0513 version. All went well, but I noticed something odd when I wanted to make some changes to my config.txt:

My Fat32 partition on SD card is populated with 72 new files, besides the files that normally reside there. The files are FSCK0000.REC - FSCK0071.REC (all 8.192 bytes exept one 49.152 bytes)

Is that normal, or is this result of some glitch that happened during the update?
Should I keep them, or can I delete all of them?

Kind of not normal. It means your FAT partition suffered corruption (which isn't really normal) and these files have been recovered by the filesystem check that runs automatically when the system boots (which is normal, but ideally you shouldn't be suffering from corruption in the first place). Given the number of files it would appear there may have been a problem with the overlays directory. You can delete the FSCK*.REC files.

If it continues to happen then it might be an indication your SD card is beginning to fail.
