[libcoap-developers] Release 4.2.1

[Olaf B. <ber...@tz...>]

Dear libcoap community,

I am pleased to announce the official release 4.2.1 of libcoap!

This release is merely a bugfix release for version 4.2.0.  Header
paths for Windows build have been corrected as well as the uninstall
target.

Moreover, the epoll() system call is now supported to facilitate
integration with other applications that have their own main loop, the
documentation in manual pages has been improved a lot. Among the new
features is a pre-processor symbol COAP_CONSTRAINED_STACK to limit the
use of automatic variables. CoAP functionality such as block-wise
transfer has been improved.

A big THANK YOU to all of you who have worked so hard at the improvement
of libcoap. Version 4.2.1 is very important on the way to the next
release 4.3.0 which will bring a number of API changes and new
functionality. Again a big thank you to Jon Shallow and many other
people for your valuable contributions!

Best regards
Olaf
