• -vet-cast
  • Looks for redundant casts or transmutes, and transmutes that should be casts
• -strict-style now enforces a lot more regarding the official Odin code base style
  • -vet-style is a much weaker form that does not have all of the same enforced options as -strict-style

  • -custom-attribute:attr1
  • -custom-attribute:attr1,attr2
  • -custom-attribute:attr1 -custom-attribute:attr2

• Add #directory (complements #file)
• Remove @(warning) and #warning
• Allow - constant_array
• Support @(extra_linker_flags) on WASM targets
• Use f32 operations when doing complex32 and quaternion64 operations to improve accuracy and performance
• Allow for when x in y { (minor oversight in syntax)
