Please let me know if I missed anything. Also, if you make any updates to
current documents - please reply to this email with either the updated
links or notifications if / when any content updates have been made in
place, without changing the document links / locations.

As a reminder, the next SC29/WG3 meeting will be held on April 22-26.
The input submission deadlines for the next WG meeting are as follows:
- April 15: deadline for registration of input contributions;
- April 17: upload deadline for registered input contributions.

The direct emails with the meeting invite including Zoom info will follow
soon. Again, due to public availability of the AHG list archive, this info
will not be shared on the AHG email list - please contact me directly if
you would like to be added as an invitee and have not been a participant in
any prior AHG meetings.

Thank you,
Vladimir
