# Changelog for RStudio Wrapper Portlet
|
||||
|
||||
All notable changes to this project will be documented in this file.
|
||||
This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
|
||||
|
||||
## [v1.5.0-SNAPSHOT] - 2021-04-21
|
||||
|
||||
- RStudio instance allocation takes into account the number of instance available in the VO and not in the context and assign the RStudio instance balancing the load.
|
||||
|
||||
- The user is always redirected to the same endpoint, until a gCore Endpoint disappears, if so a new allocation is calculated.
|
||||
|
||||
## [v1.3.1] - 2019-10-07
|
||||
|
||||
- RStudio instances returned over https now
|
||||
|
||||
|
||||
## [v1.3.0] -2017-02-21
|
||||
|
||||
- RStudio instance allocation takes into account the number of instance available in the given context and assign the RStudio instance balancing the load.
|
||||
|
||||
- Added possibility to look for service endpoint RConnector resource in the scope
|
||||
|
||||
## [v1.0.0] -2016-04-11
|
||||
|
||||
- First release
