History
FLIF was first announced in 2015, and the first stable version (named FLIF16) was released in 2016. Note that FLIF files or software created before about 2016-08 are likely to be incompatible with the current FLIF format.
Identification
FLIF files begin with ASCII "FLIF".
The byte at offset 4 is one of the characters from the ASCII string "134ACDQSTacd".
The byte at offset 5 is one of the characters from the ASCII string "012".
