Releases

We're releasing early versions of Soroban because we believe it's important to share the development process, and we want Stellar ecosystem developers and smart contract developers from other ecosystems to have a chance to experiment and provide feedback.

caution

Release candidates are software releases that are also released to the Testnet test network. Software releases may occur between Testnet releases. If you're interacting with Testnet, the recommended software versions to use in development are provided below. Releases to Testnet may include network resets and network passphrase changes.

Breaking changes note

This release includes a major overhaul of the value representation at the XDR level, which potentially breaks contracts that rely on the old type definitions, here is a summary of the changes:

  • Removed the object/value split at the XDR level
  • Expanded size of value tag from 8 to 128 cases
  • Removed types: U63, Static, Bitset
  • Added U256, I256 and special case u64 subtypes Timepoint and Duration
  • Added String which is a Bytes-like object but displays as text
  • Enhanced Symbol to have a maximum size of 32 bytes (no more 10-char limit)

SDK support has also been added/updated for these types. See xdr, env and sdk changes for more details.
