Here is a list of which FileMaker version includes which CURL version:
|FileMaker version||CURL Version|
Why do we care? Well, if you still use FileMaker before version 16, your FileMaker scripts using Insert From URL are affected by the TLS certificate bugs in older CURL versions. And if certificate verification is not done right, someone can attack your queries, gain your password or provide invalid data to your solution. So please keep FileMaker up to date!
As with MBS Plugin, Claris Inc. also regularly updates the open source libraries used. Usually you do that on the begin of the development cycle, so you have time to find and issues from the newer library version like a bug fix, which changes behavior in a way you didn't intent. e.g. we run into CURL change for email download via IMAP.
MBS Plugin 10.1 will include CURL version 7.68.0 and MBS Plugin 10.0 shipped with version 7.67.0.
