Hi, I'm still waiting for two PRs to finish the release notes.
Online upgrade: https://github.com/apache/incubator-iotdb/pull/467 Refactor the db.exception: https://github.com/apache/incubator-iotdb/pull/530 If you have time, please help to review them :) > I looked into the v0.9.0 changelist again and I am confused about IOTDB-174, > which appears in both "New Features" and "Bug Fixes". > The description of IOTDB-174 is more like "New Features"- "Add interfaces for > querying device or timeseries number ". Yes, the description of IOTDB-174 is a new feature. > But the title of the pr#435 related to IOTDB-174 is more like "Bug Fixes" - > "Fix querying timeseries interface cannot make a query by the specified path > prefix". This is because after developing the new feature, we find a bug and pr#435 is a bug-fix of this new feature. In this case, I can remove it from the "Bug FIxes" in order not to puzzle readers. > Besides, "[IOTDB-165][TsFile] Fix a example" does not only fix a bug, but > also change the TsFile structure, > which is unfortunately reflected neither from the JIRA issue title nor the pr > name. > From this example, we can also see that it is necessary to name our pr as > accurate as possible. > And the release manager better double check if there is inconsistency between > the JIRA issue and the linked pr. Agree, the pr#"Fix a example" indeed fixed a TsFileSequenceRead example, but link this to IOTDB-165 is not very clear. Besides, there are two PRs linked to IOTDB-165. PR#409 is the origin one. In this case, I will remove the "fix a example" in the "Bug Fixes". >Maybe the sync module is also worthy to mention in the change list. The pr >link is https://github.com/apache/incubator-iotdb/pull/372 ><https://github.com/apache/incubator-iotdb/pull/372>. Added.
