v1.4.2 Optional Release and Discussion

[jennijuju]

Full release note and changelog: https://github.com/filecoin-project/lotus/releases/tag/v1.4.2

This is a large, and highly recommended, optional release with new features and improvements for lotus miner and deal-making UX. The release also integrates v3 specs-actors, which implements two FIPs:

• [FIP-0007 h/amt-v3](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0007.md) which improves the performance of the Filecoin HAMT and AMT.
• [FIP-0010 off-chain Window PoSt Verification](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0010.md) which reduces the gas consumption of SubmitedWindowedPost messages significantly by optimistically accepting Window PoSt proofs without verification, and allowing them to be disputed later by off-chain verifiers.

Note: This release does NOT set an upgrade epoch for v3 actors to take effect. That will be done in the upcoming 1.5.0 release. However, if you run some customized lotus and want to get prepared for the upcoming network v10 upgrade, you may start to update your software based on this release.
