>>
>>
>>    - X3D Tooltips 4.0 also highlights all changes in yellow

>>    -
>>    https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-DIS/Part01/versionContent.html

>>
>>
>> Suggested: should we create an X3D4 Migration Guide to help

>>
>>
>>
>> *Volunteers please?  *Creating some form of X3D4 Migration Guide

>>
>>
>>
>>
>>
>>    1. *All other business*.
>>
>>
>>
>> Good discussions on download statistics (X3D-Edit, FreeWrl) and a variety
>> of other topics... we’re having fun now!
>>
>>
>>
>> As ever, many thanks for the work of many contributors.  Deep breath… wow.

>> No Web3D member-only information is included in these minutes… but please
