Namada 0.31.3

Namada 0.31.3 is a patch release that fixes various issues.

  address is specified. (#2522)

  set. (#2578)

• Adds some useful internal addresses, such as PoS, to the wallet upon join-
  network. (#2543)

  formatted output. (#2558)

Namada 0.31.2

⚠️ Warning: This release contains a critical issue with Tendermint request ordering which has been fixed in 0.31.2.

Namada 0.31.1 is a patch release that fixes the memo processing for some transactions and improves logs related to ledger startup and the wallet.

  (#2490)
• Reworks the way the ledger waits for genesis start. It now fully initializes the node and
  outputs logs before sleeping until genesis start time. Previously it would not start any
  processes until genesis times, giving no feedback to users until genesis time was reached.

  epoch change. This PR fixes this to use the tokens found in genesis belonging to the MASP
  rewards whitelist instead of hardcoding the tokens.

  every new applied tx and on reading state from disk on start-up. Replaced
  recursion from RocksDB that was growing stack size with a loop.
