Decoded Message Bodies

Toncenter API now decodes message bodies using hundreds of known TLB schemes and returns the result in the Message.message_content.decoded field. Previously, only the text_comment type was recognized; the API now supports 800+ TLB schemes. This means responses may include new decoded types and richer structures. Update your parsers to read decoded defensively.

If your dApp’s smart contract uses a TLB scheme that isn’t decoded yet, please submit a pull request with the scheme definition.
