@ -410,6 +410,20 @@ Bugfixes:
|
||||
* Parser: Fix incorrect source location for nameless parameters.
|
||||
* Command Line Interface: Fix internal error when compiling stdin with no content and --ast option.
|
||||
|
||||
|
||||
### 0.4.26 (2019-04-29)
|
||||
|
||||
Important Bugfixes:
|
||||
* Code Generator: Fix initialization routine of uninitialized internal function pointers in constructor context.
|
||||
* Type System: Use correct type name for contracts in event parameters when used in libraries. This affected code generation.
|
||||
|
||||
Bugfixes:
|
||||
* ABIEncoderV2: Refuse to generate code that is known to be potentially buggy.
|
||||
* General: Split rule list such that JavaScript environments with small stacks can use the compiler.
|
||||
|
||||
Note: The above changes are not included in 0.5.0, because they were backported.
