[lwip-users] lwIP 2.1.3 released

[address@hidden]

lwIP 2.1.3 is now available from the lwIP download area on savannah [1]
or via git (using the STABLE-2_1_3_RELEASE tag).

This is again a bugfix-only release on the 2.1.x branch fixing numerous
smaller bugs. For a changelog, see the git log here:

https://git.savannah.nongnu.org/cgit/lwip.git/log/?h=STABLE-2_1_3_RELEASE

As always, all users are strongly suggested to upgrade (should be a
matter of copying the new files only, no changes required)!

Contrib has still not been changed since 2.1.0, so 'contrib-2.1.0.zip'
is still valid.

Thanks for all contributions!

Simon
