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, upstream has been updated via 7efe10ec5fc772f5328b35ba6716bde815212b45 (commit) from 6d550ddd129b18cf800eab604f74536754526cd8 (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.
