cve-bin-tool 3.2.1

CVE Binary Tool 3.2.1

on Python PyPI

Due to a change in the data used for the curl data source, we're issuing a slightly out of band point release for users unable to use 3.2.

There are a number of checker updates to address false positives, new checkers, and other bug fixes and features as described below.

One commonly requested feature has made it into this release: generation of SBOMs. Please try it out and let us know where it can be improved!

Thanks especially to the many new contributors in this release (you can see the list at the bottom)

• Many of you joined us via the Google Summer of Code 2023 selection process: I wish we'd had mentors and slots available to have more of you as paid contributors this year!
• Some of you also joined us via the Intel Open Source Hackathon: thank you so much for taking the time to work with us and it's been a delight to work with so many experienced coders during the event.
• And some of you just stopped by on your own with great ideas and fixes. Thank you!
