What's Changed

• Drop ancient Go versions and add modern ones by @g7r in #44
• Respect TypeModifierOmitStackTrace in Builder by @g7r in #43

Full Changelog: v1.1.1...v1.2.0

• Fixed panic on unwrapping nil typed as *errorx.Error#42

Added support of go 1.13 errors package:

• errors.Unwrap() works properly for errorx.Error
• errors.Unwrap() respects opaque (errorx.Error::Wrap()) and transparent (errorx.Decorate()) wrapping contract
• Unwrapping via errors.Unwrap() works with chains of errorx and non-errorx errors
• The same behaviour is true for errors.Is()

Add go modules support.

• Panic() now handles stack traces better, especially across multiple goroutines
