Hi, I just published a new version of the launcher: 1.4 (http://pharo.org/download <http://pharo.org/download>) Improvements: Add Origin Template Column Simplify Timestamp Printing Bug fixes: #233 Cannot launch recent Pharo 7 images
This version mainly solves the problem of launching recent Pharo 7.0 images. Once this version is downloaded, do not forget to delete the folders related to 70 vms in the Pharo/vms folder. This way, Pharo Launcher will download the latest one. By the way, it also comes with some UI improvements (contributed by Sean and Tim). I will work on a new version with a VM manager able to list locally available VMs, and a way to update or delete them. This new version will be based on Pharo 7 because Pharo Launcher development switched to github (https://github.com/pharo-project/pharo-launcher) and upcoming features are based on Pharo 7 (new UI, model refactoring).
