After  Launching its first community in Mai 2022, The Encointer team was able to gather a lot of experience how the protocol can be improved for better growth possibilities and user experience. Moreover, a minor attack vector has been discovered and [one critical bug](https://github.com/encointer/encointer-parachain/issues/138) needs fixing through runtime upgrade that has only been fixed through a workaround currently.

Please find the release notes along with the srtool build here:
[https://github.com/encointer/encointer-parachain/releases/tag/1.2.0](https://github.com/encointer/encointer-parachain/releases/tag/1.2.0)

## Testing

The most invasive changes have been successfully tested on our Testnet Gesell during our demo at decoded 22

Testing pallets on Testnet Gesell (solo) [completed](https://github.com/encointer/encointer-node/issues/240)

Testing on Testnet Lietaer (rococo) [completed](https://github.com/encointer/encointer-parachain/issues/141)

## Update Process

As a common-good parachain, Encointer runtime can only be upgraded through Kusama governance. It is important that the runtime upgrade happens during the registering phase of Encointer's ceremony lifecycle. We will therefore submit a preimage later this week and propose a referendum to be timed with support of the Kusama's technical committee such that the enactment happens during the desired range of days.

Best option: Enactment between Aug 4th and 9th

Fallback: Enactment between 14th and 19th
