Besides, we can see many new features are introduced in the master branch, and many of them are tested for a long time. Meanwhile, some new features that are in development, like aligned time series (i.e., vector data), upgrading Thrift from v0.12/0.13 to v0.14.1 are almost done but need more time to test. Therefore, I'd like to begin to checkout rel/0.12 branch and start to release v0.12 in the next few days. All unmerged new features will be released in v0.13 (some security-related issues can be released in v0.12.1, like upgrading thrift v0.14.1). How do you think?
