ethereum/solidity v0.3.0

Version 0.3.0 (includes breaking changes)

on GitHub

This version is synchronized to the Homestead changes on the main Ethereum network and introduces various breaking changes.

BREAKING CHANGES:

• You should not rely on division for literals resulting in a (truncated) integer. This is still the case but will change once we implement fixed point types, i.e. in the future 1/2 == 0.5 will be true, currently we have 1/2 == 0. Note that this only applies to literals ((2 + 7) / 2) and not variables (x / 2).
• Library calls now default to use DELEGATECALL (e.g. called library functions see the same value as the calling function for msg.value and msg.sender).
• Added new keywords assembly, fixed, ufixed, fixedNxM, ufixedNxM (for various values of M and N), inline in preparation for future features.

Features:

• <address>.delegatecall is provided as a low-level calling interface for DELEGATECALL

Bugfixes:

• Fixed a bug in the optimizer that resulted in comparisons being wrong.
