v5.10.0

v5.10.0 (2026-08-17)

Added

• Support for AVM 13 style varint encoding for branches in assemble

• Off-curve autosalt: a logicsig whose program hash (concatenated to the domain separator Program) decodes to an Edwards25519 point gets a trailing intcblock salt (regardless of AVM version) at assemble time, so its address cannot double as a valid public key. Contracts are never salted by default.

• autosalt option on the logicsig decorator and Contract classes to override the default:
  True forces salting, False disables it, and contradicting overrides emit a warning. The resolved setting is recorded as #pragma autosalt in the TEAL output.

• Support for new AVM 13 opcodes and fields:

  • New hashing primitives: SHA512 and poseidon2.
  • AppBox family ops, a series of opcodes used to read and write boxes from other applications.
  • app_params_set and two new boolean settable AppParams fields: AppForeignBoxReads (indicates that this app's boxes may be read by any app) and AppFamilyBoxAccess (indicates that this app's boxes may be read and written by any app -existing or future- with the same creator).
  • New application parameter AppSizeSponsor: an address which, if non-zero, is responsible for the app's extra pages and global storage MBR.

Changed

• Underlying representation for CompiledContract to accomodate new extra page limits.
