user125322: I have some problem with sending Bitcoin from Bitcoin Core v.0.14. When entering the address in recipient field it becomes red. And I noticed that the address to which the translation needs to be made does not correspond to my. My address contains digits, small and bit letters and address that i need to send contains digits and small letters only and it it has a more length. First 4 characters are "bc1q".  Can you help me in resolving this problem. Thanks!

user13866: As Pieter Wuille explained:
An address starting bc1 is a BIP173 address (using Bech32 encoding). Support was added in Bitcoin Core 0.16 (released in 2018).
You can just update to the latest version immediately (currently 0.21.1). Make a backup of your wallet.dat file in case something goes wrong, but that's unlikely.
