1.0.0 release
by Waldemar Brodkorb 04 Feb '15

04 Feb '15

Hi Embedded Hackers, on Sunday I decided to prepare for 1.0.0 release. I have tagged 1.0.0 and prepared tarballs on http://downloads.uclibc-ng.org/releases/ I updated OpenADK and Embedded-Test to use 1.0.0. Now I starting to get uClibc-ng included in buildroot and OpenWrt projects. If you find any bugs or have any suggestions, don't hesitate to mail me. The releases get funky belgian beer names as code names. best regards Waldemar
