TiDB 3.0.7 Release Notes

Release date: December 4, 2019

TiDB version: 3.0.7

TiDB Ansible version: 3.0.7

TiDB

  • Fix the issue that the lock TTL's value is too large because the TiDB server's local time is behind PD's timestamp #13868
  • Fix the issue that the timezone is incorrect after parsing the date from strings using gotime.Local #13793
  • Fix the issue that the result might be incorrect because the binSearch function does not return an error in the implementation of builtinIntervalRealSig #13767
  • Fix the issue that data is incorrect because the precision is lost when an integer is converted to an unsigned floating point or decimal type #13755
  • Fix the issue that the result is incorrect because the not null flag is not properly reset when the USING clause is used in Natural Outer Join and Outer Join #13739
  • Fix the issue that the statistics are not accurate because a data race occurs when statistics are updated #13687

TiKV

  • Make the deadlock detector only observe valid Regions to make sure the deadlock manager is in a valid Region #6110
  • Fix a potential memory leak issue #6128
