Hi there, thanks a lot for the graet development work!
I made my tests with 2.0.1 with a new installed copy of my flows; everything worked fine.
Then i made the upgrade in the productive environment. No functional deficites, but there is something wrong with the language settings. All labels in the editor UI have no teaxt content (e.g. the deploy button is called "deploy.deploy". Changing the language and restart made no difference. Environment variable LANG ist set to de-DE; OS is MS Windows (germam), that all worked fine beforee the upgrade.
