Pre-release
The first release candidate is here! This is the first release which could become the final
v4.0.0
. Any subsequent release candidates should only contain bug fixes: no API changes,
breaking or otherwise.
Breaking Changes
- We've renamed some of the generated message methods on the
ContractRef
struct. They
have been changed from_checked
totry_
(#1621) - We have removed the
Default
implementation forAccountId
s. This is because of
security concerns around the use of the zero address which has a known private key in
thesr25519
anded25519
curves (#1255). - We have replaced the
CallBuilder::callee()
method with acall()
method and also
added adelegate()
method. This streamlines theCall
andDelegateCall
workflows
(#1636)
