# [2.0.6.0-2.0.6.0\_experimental\_2021-04-09](https://github.com/duplicati/duplicati/releases/tag/v2.0.6.0-2.0.6.0_experimental_2021-04-09) ## First experimental build in over a year! We have been hard at work adding new features and fixing issues. This experimental release is a roll-up of all the fixes since the last experimental build and is expected to cause very few issues when upgrading. A big thanks to all Duplicati contributors, supporters, fans and users for keeping the project evolving and improving. ### New in this version - Added Tardigrade backend - Added Tencent Cloud Object Storage (COS) - More Docker image versions - Improved long-path support on Windows We changed some larger things that you should be aware of when upgrading. ### The SSH backend has been updated This update increases the security by prefering stronger encryption algorithms. However, this _can_ cause failing backups as the host key is reported as “changed”. If this happens, edit the backup and update the host key. ### Database version update from v10 to v11! Downgrade from this version requires manually adjusting the version number in the database. The additions can be re-applied if the database is upgraded again later. ### Other changes that needs attention - Duplicati now requires Mono 5.10 or greater - S3 and Sharepoint option names on commandline now uses `-` for consistency (previously used `_`)
