This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "uClibc-ng - small C library for embedded systems".

The branch, master has been updated via cc865abe4b1194a28da9bb900e2a07a2c390f4e7 (commit) from 6da12ac15832812877db27adb3ebe898fbb36dc3 (commit)

Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below.
