Subject: [EXTERNAL] [lwip-users] Release Notes
Where can I find the release notes for versions 2.2.0 back to 2.1.2? The Wiki (https://lwip.fandom.com/wiki/Release_notes) ends a 1.3.0 and
http://savannah.nongnu.org/projects/lwip/ ends at 2.1.2, which is what I’m currently using, but it looks like the latest may be 2.2.0, according to my hardware/SDK vendor, NXP.
