v4.0.4

• Update ANTLR to v4 to remove transient targeting of NETStandard 1.6.0, which caused problems when publishing solutions on a modern .NET (Thanks @markcanary!)

v3.2.6

• Flag to control if string parameters should be converted to decimal (the default) or double

v3.1.8

• New function Atan2

v3.0.4

Several syntax changes to the grammar:

• Exponentiation operator **
• Case insensitive operators and key words (e.g. AND or True)
• Support numbers with trailing dot (e.g. 47.)
• Support for positive sign (e.g. +5)

While these changes in themselves wouldn't introduce compatibility issues with previously valid statements, code that relies on statements with these constructs being invalid would be affected. The grammar also had to be regenerated with a new version of ANTLR with some fixes to it since it was clear that the generated source code had been modified manually. Manual review indicates that the regenerated grammar is identical, but because of both these reasons this is released as a new major version.
