The experience for adding new people to organizations was reworked.
Instead of forcing people to join organizations, they must now accept an invitation sent to their email
address.
Invitations can be sent to people who already have Valohai accounts, as well as to those who don't.
This also allows you to create invitations that add people to custom teams while they are being invited.
User experience improvements
Waiting for an execution to start and logs to appear is no longer as boring.
The UI is smarter about determining the step size for linear hyperparameter optimization sweeps.
The Revert button in the Create Execution/Task view was made a little subtler.
