According to PANews on October 27, Casey, the founder of Ordinals, said on the X platform that if users use ord to send runes, please upgrade to ord 0.21.2. This version fixes a somewhat serious bug, that is, "ord wallet send" does not create change outputs in some cases, which may cause runes to be lost. This bug has been fixed in this PR. When using "ord wallet send", the wallet must select an input UTXO containing enough runes to cover the amount sent. This release also includes: ord wallet sign can be used to sign messages with an address of the wallet; if the casting is currently open, the casting progress is only displayed on /rune; the casting progress is also displayed incorrectly, which has now been fixed.
