+[1.26.4](https://github.com/bird-house/birdhouse-deploy/tree/1.26.4) (2023-06-06)
+------------------------------------------------------------------------------------------------------------------
+
+## Changes
+- Jupyter env: new version with latest RavenPy
+
+  See https://github.com/Ouranosinc/PAVICS-e2e-workflow-tests/pull/119 for more
+  details.
+
+
+[1.26.3](https://github.com/bird-house/birdhouse-deploy/tree/1.26.3) (2023-06-01)
+------------------------------------------------------------------------------------------------------------------
+
+## Changes
+- Jupyter env: new version with latest Xclim and RavenPy
+
+  See https://github.com/Ouranosinc/PAVICS-e2e-workflow-tests/pull/115 for more
+  details.
+
+- Raven WPS: new version to match with new RavenPy inside the Jupyter env
+
+  See https://github.com/Ouranosinc/raven/compare/v0.14.2...v0.18.1 for more
+  details.
+
+## Fixes
+- Notebook autodeploy: unable to read the `env.local`
+
+  When `env.local` is a symlink we need to volume-mount the destination of the
+  symlink so it resolves inside the notebook autodeploy container.
+
+  This will allow notebook autodeploy config variable to be set in `env.local`.
+
+  Also had someone changed the value of `JUPYTERHUB_USER_DATA_DIR` in `env.local`,
+  it would not have worked without this fix.
+
+  This is a non-breaking fix.
