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 da932d59161a2d833596be5443c81ff244d2db58 (commit) via 638a23483b40c5b606ee323e6612e7e454e5154b (commit) via bff3a664e6a2a367bf159c3089df1fe6f093bfb1 (commit) via f8e05f3850e51673522216f23533bf7146359dcd (commit) via 067637375658047d70c296606ae17ef0bc86499d (commit) via d6da534cbf05dc4d09221881afd49b275ca7cd29 (commit) via 926a698c5ac69b599014ce147cc814343f0aaa4f (commit) from 88842f7126daccf205204be05d3143c73fa0624d (commit)
