About this release

First Lima release candidate.

Changelog:

We now have FATE. (The initial version of FATE is released as VM version 0x05).
The transaction can now be performed while the channel is not active on-chain (The channel solo closing sequence had been initiated and the channel is not yet closed), this is a consensus breaking change available after the Lima fork.
The state channel FSM after the Lima fork accepts a shutdown message while the channel is being closed unilaterally.
Introduces AEVM version 0x06, available from Lima consensus. This is a fine-tuned version of the AEVM version 0x04 introduced in the Fortuna consensus.
Extends transaction signing - also allow signatures of the transaction hash. The transaction serialization is potentially long, so signing the transaction hash means less cryptographic work.
Obsoletes the old State Channel off-chain transaction type which contained the list of updates that produced the latest state_hash. The new transaction type is available since Fortuna hard fork and the FSM is producing such transactions ever since. This detaches the off-chain protocol from the on-chain one and allows development of unique off-chain protocols that don't need their updates to be serializable on-chain.
For existing state channels where the latest co-authenticated state is an off-chain transaction based on the old version, it is suggested to make a new co-authenticated transaction which is using the new serialization. For currently existing state channels which latest co-authenticated state is an old version off-chain transaction is suggested to make a new co-authenticated transaction that is using the new serialization. If the other party refuses to authenticate a new round or is simply missing, one can use the solo closing sequence instead.
Metadata objects (of type binary) can now be added to an offchain update transfer request. These objects serve as comments and are not part of the signed transaction, nor do they affect the offchain state trees. This is an incompatible change in the serialization of offchain updates, but old offchain updates can still be deserialized. When creating a channel with a party running an older node version, add version_offchain_update=1 to the channel params.

The node is able to start from a database produced by v4.* releases. For the rest, this release is not backward compatible with v4.* releases.
