Hi, I'd like to propose the 2nd voteable release candidate (RC4) of Apache Arrow version 0.12.0. This is a major release consisting of 610 resolved JIRAs [1].
We've hit several roadblocks during the release. The most recent issues were caused by the simultaneous releases of numpy, pandas, and even the great conda-forge compiler migration, which was finished yesterday [10]: - RC0: the source archive didn't include required files to build gandiva-glib documents, also causing failed binary build for Debian Stretch [6]. - RC1: compatibility issues with the just released pandas version 0.24.rc1 [8] - RC2: voted, but decided to cut a new one because of faulty safe casts [11] - RC3: various conda-forge problems and compatibility with pandas 0.22 [9] This release candidate is based on commit: 8ca41384b5324bfd0ef3d3ed3f728e1d10ed73f0 [2] The source release rc4 is hosted at [3]. The binary artifacts are hosted at [4]. The changelog is located at [5]. Please download, verify checksums and signatures, run the unit tests, and vote on the release. See [7] for how to validate a release candidate. Please use the verification script from the master, because it has required a patch to work after the recent conda-forge compiler migration [12]. The vote will be open for at least 72 hours.
