v4.8.0

Bug Fixes

• Fixed migrate exiting the process or silently continuing on errors thrown by migration scripts, contract calls, or deployer steps
• Fixed flatten truncating its output when stdout is piped
• Fixed waitForTransactionReceipt polling indefinitely when a transaction never appears

Improvements

• Faster artifact lookup in the resolver
• Clearer error messages for invalid imports, missing npm packages, and missing files within an npm package
• unbox looks up the template at the requested Git ref (e.g., user/repo#v1.2.3)
• Dropped ast from per-contract artifacts to shrink build output; the full AST is still emitted to build_info_directory
• compile no longer supports contract files outside contracts_directory

Dependencies

• Upgraded tmp from 0.0.33 to 0.2.6

Removals

• Removed colors dependency (chalk was already in use for the same purpose)
• Removed original-require dependency (migration sandbox now uses Node's built-in module loader)
• Removed solc dependency (soljson wrapper vendored in-tree)
• Removed vcsurl dependency (GitHub URL parsing now inline)
