Oracle SQL Developer 21.4.2 & SQLcl 21.4.1 are now available

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

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.

What about SQLcl?

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