aepp-sdk v10.0.0
Today we released a new major release of the JavaScript SDK. We recommend everybody to update to the latest version due to many important changes.
Check it out on npm:
Please keep in mind that the release ships some breaking changes which you need to adapt your aepps to. Especially if you have an aepp that interacts with smart contracts!

aeproject v4.0.0-alpha.2
Today we also released an alpha version of the upcoming aeproject version which introduces utilities that allow you to make use of new devmode features. One very important feature here is for example the possibility to make snapshots and rollback to a state of the chain. Also the node in devmode can emit blocks instantly and doesn’t rely on mining so that you no longer waste CPU resources on your local machine. Under the hood the v4.0.0-alpha.2 release already integrates the new aepp-sdk v10.0.0 
Check it out on NPM:
And install with npm install -g @aeternity/[email protected]
We don’t have an easy upgrade-path for your old aeproject repositories yet. A migration guide and general documentation will follow. For the moment you need to stick to the help of the CLI commands aeproject provides.
For aeproject, independent of it’s current alpha state, we also recommend to test it at least for new projects and provide us feedback! You will be way more productive compared to the old version 
Have fun testing and if you have any questions let us know - we are happy to help!
