A very short post for a very big deal. FIX parser is now able to parse repeating groups! Repeating groups have been the most requested feature since the app was launched.

I hesitated adding repeating groups because they break the simplicity of parsing FIX where keys are unique. Repeating group tags have to be identified and a mechanism has to be provided to handle custom repeating groups.

The current implementation bypasses all of that. The algorithm infers the existence of repeating groups from the data in the FIX message, removing the need for keeping track of custom or standard NoXXX tags.
