## Feature **M132 release** The M132 release of Vertex AI Workbench instances includes the following: * The new scheduler Jupyter plugin (`scheduler-jupyter-plugin`) is now preinstalled in the Jupyterlab 4 environment, with support for both the Cloud Composer and Vertex AI notebook schedulers. * Updated the Dataproc JupyterLab plugin (`dataproc-jupyter-plugin`) to version 0.1.90. * Patched bugs related to the managed end user credentials feature (Preview), resolving an incompatibility with listing Dataproc remote kernels. * Patched a bug that caused instances with disabled proxy access to get stuck in provisioning. * Removed the archived Debian 11 backports repository, resolving an issue with running `apt update` within the instance.
