Truffle: Upgrade to solc v0.4.23

[TovarishFin]

I know that the new version was just released today but I just wanted to check if there are any estimates on when a new version will be released supporting this. I ask because I have some frequently called functions that will cut gas costs in half with features in the new solc version.

We are also going to have a large set of contracts audited in 2 to 3 weeks. It would be great to be able to use the new features!

Side Note: Does anyone know if there are any breaking changes from [email protected] if I were to just install [email protected] directly in truffle?

Thanks!

Solc 0.4.22 also adds error reason strings for revert and require. This is a feature I've been waiting for a long time. Would be great to have truffle suite support soon.

@TovarishFin We opened PRs bumping solc this morning. There's a small issue with 0.4.22 breaking the truffle-debugger which we have to resolve, but goal is to publish a patch w/ 0.4.22 ASAP - in the next couple of days hopefully.

0.4.23 just released with fix:

If a contract has both a new-style constructor (using the constructor keyword) and an old-style constructor (a function with the same name as the contract) at the same time, one of them will be ignored. There will be a compiler warning about the old-style constructor, so contracts only using new-style constructors are fine.

@k06a Ok great - we'll release with 0.4.23 this afternoon as long as everything runs clean and they list the release on Github here.
