[Numpy-discussion] NumPy 1.15.4 release

Hi All, Just a heads up that I am planning on making a 1.15.4 release this coming weekend. The only fixes planned at this point are - BUG: Fix fill value in masked array '==' and '!=' ops, #12257 <https://github.com/numpy/numpy/pull/12257> - BUG: clear buffer_info_cache on scalar dealloc, #12249 <https://github.com/numpy/numpy/pull/12249> If there are other fixes that you think needed, please let me know.
