+ - RStudio v.1.2.5033;
+ - Apache Spark v.2.4.4 for standalone cluster;
+
+**AWS:**
+- Added support of new version of Data Engine Service (EMR) v.5.28.0;
**GCP:**
-- added billing report to monitor Cloud resources usage into DLab, including ability to manage billing quotas
-- updated versions of installed software:
- * Dataproc 1.3
+- Added support of new version of Data Engine Service (Dataproc) v.1.4;
+- Added new template Superset v.0.35.1;
-## Improvements in v2.2
+## Improvements in v2.3
**All Cloud platforms:**
-- implemented login via KeyCloak to support integration with multiple SAML and OAUTH2 identity providers
-- added DLab version into WebUI
-- augmented ‘Environment management’ page
-- added possibility to tag Notebook from UI
-- added possibility to terminate computational resources via scheduler
+- Grouped project management actions in single Edit project menu for ease of use;
+- Introduced new "project admin" role;
+- SSO now also works for Notebooks;
+- Implemented ability to filter installed libraries;
+- Added possibility to sort by project/user/charges in 'Billing report' page;
+- Added test option for remote endpoint;
-**GCP:**
-- added possibility to create Notebook/Data Engine from an AMI image

-## Bug fixes in v2.2
+## Bug fixes in v2.3
**All Cloud platforms:**
-- fixed sparklyr library (r package) installation on RStudio, RStudio with TensorFlow notebooks
+- Fixed a bug when Notebook name should be unique per project for different users, since it was impossible to operate Notebook with the same name after the first instance creation;
+- Fixed a bug when administrator could not stop/terminate Notebook/computational resources created by another user;
+- Fixed a bug when shell interpreter was not showing up for Apache Zeppelin;
+- Fixed a bug when scheduler by start time was not triggered for Data Engine;
+- Fixed a bug when it was possible to start Notebook if project quota was exceeded;
+- Fixed a bug when scheduler for stopping was not triggered after total quota depletion;
-**GCP:**
-- fixed a bug when Data Engine creation fails for DeepLearning template
-- fixed a bug when Jupyter does not start successfully after Data Engine Service creation (create Jupyter -> create Data Engine -> stop Jupyter -> Jupyter fails)
-- fixed a bug when DeepLearning creation was failing
-
-## Known issues in v2.2
-**All Cloud platforms:**
-- Notebook name should be unique per project for different users in another case it is impossible to operate Notebook with the same name after the first instance creation
+**AWS:**
+- Fixed a bug when Notebook image/snapshot were still available after SSN termination;
**Microsoft Azure:**
-- DLab deployment is unavailable if Data Lake is enabled
-- custom image creation from Notebook fails and deletes existed Notebook
+- Fixed a bug when custom image creation from Notebook failed and deleted the existing Notebook of another user;
+- Fixed a bug when detailed billing was not available;
+- Fixed a bug when spark reconfiguration failed on Data Engine;
+- Fixed a bug when billing data was not available after calendar filter usage;
