Release 0.11.0

• Upgrade procedure
  • The release must be applied via cosmovisor and Upgrade Proposal transactions, see pool-upgrade-how-to.md.
  • The upgrade name must be equal to v0.11.0.
  • The release must be applied to all nodes (Validators, Observers, Sentries, etc.)
  • All upgraded nodes must be at 0.10.0 with cosmovisor enabled.
• The release contains a number of breaking changes which leads to the consequences mentioned below.
• Adding new nodes to the running pool (Test Net in particular) must be done via one of the ways described in running-node-in-existing-network.md. Starting a new node from the genesis state as described in running-node.md will not work. There are instructions on how to add a new node to the Test Net:
  • Adding new Observer nodes to Test Net
  • Adding new Validator nodes to Test Net
• Querying Certificates:
  • Certificates created before 0.10.0 must be queried as follows:
    • subject is a human readable string with unparsed VID/PID OIDS (before More human friendly way to display Matter OIDs in the certificates is fixed);
    • subject_key_id is a hex string without leading zeros.
  • Certificates created after 0.11.0 must be queried as follows:
    • subject is a certificates's Subject's DER sequence bytes encoded in base64 format;
    • subject_key_id is a hex string with leading zeros.
    • See transactions.md.
  • See Certificate SKID and subject should be unambiguous format for X509 transactions for details.
  • The reason for that difference is that data migration hasn't been done for the Test Net, so certificates created before 0.10.0 should be queried in the "old" way.
