v0.2.0

In short

• A consensus upgrade is scheduled at block height 78440. This upgrade aims to balance pool sizes and discourage the formation of large, dominating pools, as part of our ongoing commitment to improving network decentralization.
• Introduction of the new MLS01 standard, replacing the legacy version. This standard allows issuers to have optional control over the token supply. This is also available starting from block 78440.
• Added ability for token issuers to optionally enable freeze/unfreeze actions on tokens.
• Enhanced authority management, allowing token issuers to change the authority responsible for controlling supply and freeze/unfreeze actions.
• Included an OP_RETURN output capable of containing a full hash.
• Implemented several bug fixes and code improvements.
