v9.5.4

What's Changed

When passing string arguments to contract operations, such as deploy, call and upgrade, mxpy interpreted it as unknown arguments. All string arguments should be prefixed with str:.

Another issue happened when signing transactions by hash with guarded accounts. This is now fixed.

What's Changed

• Raise error when given string argument without prefix by @popenta in #420
• Fix transaction signing by @popenta in #421
