The GIFLIB project maintains the giflib service library, which has been pulling images out of GIFs since 1989. It is deployed everywhere you can think of and some places you probably can't - graphics applications and web browsers on multiple operating systems, game consoles, smartphones, and likely your ATM too.
Yes, this code is he reason GIFs were in Mosaic, the first web browser that could do inline graphics; it is the implementation Andreesen and Bina used.
This is very mature, stable, small-footprint code with minimal dependencies (suitable for use in embedded deployments) that needs only occasional very minor bugfixes. Test reports from odd platforms and better regression tests are particularly welcome. Don't try to redesign it, applications beyond counting would break if you did.
It's "GIFLIB" in caps as a nod to the code's origins in the dark and backward abysm of MS-DOS, but Unix hackers are encouraged to spell it "giflib" in deference to local conventions. :-)

security:
This is a point release intended to clear up a couple of CVEs and
apply point fixes that have been accumulating since 5.2.1
There are a few unresolved (but minor) memory leaks related to design issues in the API that still need to be resolved. Expect those fixes in the next release.
