Pre-release testing of 2.3.0-rc1 revealed serious bugs (#1251, #1252) that were introduced during the 2.3.0 development window. Accordingly, we're publishing a second release candidate for 2.3.0 that fixes these issues. We expect the official release of 2.3.0 next week; thanks for your patience.
Thanks to @mogad0n for help testing 2.3.0-rc1!
