Ethereum (ETH) Released Solidity Version 0.6.8This release of Solidity fixes three important bugs in the code generator:
a missing callvalue check for constructors
a bug connected with array slices for arrays containing dynamic types
literal strings containing backslash characters in connection with ABIEncoderV2
In addition to that:we introduced a recommendation to use
SPDX license identifiers for all source files which are also stored in the contract metadata
it is possible to access the min and max values of an integer type directly
WebAssembly support has been extended
Important Bugfixes:
Add missing callvalue check to the creation code of a contract that does not define a constructor but has a base that does define a constructor.
Disallow array slices of arrays with dynamically encoded base types.
String literals containing backslash characters can no longer cause incorrect code to be generated when passed directly to function calls or encoding functions when ABIEncoderV2 is active.
Language Features:
Implemented type(T).min and type(T).max for every integer type T that returns the smallest and largest value representable by the type.
Compiler Features:
Commandline Interface: Don't ignore --yul-optimizations in assembly mode.
Allow using abi encoding functions for calldata array slices without explicit casts.
Wasm binary output: Implement br and br_if.
Bugfixes:
ABI: Skip private or internal constructors.
Fixed an "Assembly Exception in Bytecode" error where requested functions were generated twice.
Natspec: Fixed a bug that ignored @return tag when no other developer-documentation tags were present.
Type Checker: Checks if a literal exponent in the ** operation is too large or fractional.
Type Checker: Disallow accessing runtimeCode for contract types that contain immutable state variables.
Yul Assembler: Fix source location of variable declarations without value.
We especially thank all the contributors that made this release possible:
