ethereum/solidity v0.4.10

Version 0.4.10

on GitHub

This release is focused on stability and also introduces some new smart contract safety features: require, assert and transfer. Note that the new revert function will only be gas-efficient starting from homestead.

Features:

• Add assert(condition), which throws if condition is false (meant for internal errors).
• Add require(condition), which throws if condition is false (meant for invalid input).
• Commandline interface: Do not overwrite files unless forced.
• Introduce .transfer(value) for sending Ether.
• Code generator: Support revert() to abort with rolling back, but not consuming all gas.
• Inline assembly: Support revert (EIP140) as an opcode.
• Parser: Support scientific notation in numbers (e.g. 2e8 and 200e-2).
• Type system: Support explicit conversion of external function to address.
• Type system: Warn if base of exponentiation is literal (result type might be unexpected).
• Type system: Warn if constant state variables are not compile-time constants.

Bugfixes:

• Commandline interface: Always escape filenames (replace /, : and . with _).
• Commandline interface: Do not try creating paths . and ...
• Commandline interface: Allow long library names.
• Parser: Disallow octal literals.
• Type system: Fix a crash caused by continuing on fatal errors in the code.
• Type system: Disallow compound assignment for tuples.
• Type system: Detect cyclic dependencies between constants.
• Type system: Disallow arrays with negative length.
• Type system: Fix a crash related to invalid binary operators.
• Type system: Disallow var declaration with empty tuple type.
• Type system: Correctly convert function argument types to pointers for member functions.
• Type system: Move privateness of constructor into AST itself.
• Inline assembly: Charge one stack slot for non-value types during analysis.
• Assembly output: Print source location before the operation it refers to instead of after.
• Optimizer: Stop trying to optimize tricky constants after a while.
