## 6.30.0a0
## 6.30.1

Pre-release to allow further testing of subshell implementation.
This is a bugfix release to fix a significant bug introduced in 6.30.0 that allowed control messages to be handled concurrently rather than sequentially which broke debugging in JupyterLab and VSCode.

([Full Changelog](https://github.com/ipython/ipykernel/compare/v6.29.5...5d90d9e10425886deb4b0f1676b14b1701522b3c))

## 6.30.0

This release fixes three bugs but is primarily a maintenance release bringing support for Python 3.13 and updating dependencies. It does not include subshells which will be in the upcoming 7.0.0 release. Users and downstream libraries that wish to avoid subshells should pin to `ipykernel < 7`.
