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?

FSCKxxx.REC means File System check record.
Usually are created if you are not closing down the operating system the "normal" way, like you take the battery out. Linux always check the file system at bootup and if something "not-normal" (any left overs from improper close down) are found then a FSCHxxx.rec file is created to be analysed by the system administrator.
Yes, it is safe to delete them. Sometimes I have them if I am restoring my Pi backups by Clonezilla
