We published two updates last night, both maintenance releases, aka bug fixes only.

Released January 19, 2022.

That being said, everyone should upgrade their SQL Developer to this version.

  1. It fixes insight/query execution performance issues in 21.4.1
  2. It updates the log4j library to 2.17.1

You can find the full list of bug fixes here.

Change plans and Oracle Change Manager.

What about SQLcl?

The primary bug fix here was also fixed for SQL Developer.


This can be bad, as $ is a valid character for Oracle object names, like… V$TEMP.
