'''''An appeal to record as many sessions as possible''''' The Technical Product Management team in The Qt Company kindly asks to record as many sessions as possible. Unfortunately, there is a two-day workshop with another team on exactly the same days and no one from PM will be able to attend the live presentations. Last year, there were hesitations regarding recording. Please make it possible this year. If required recodings will be for internal use and will never be published for public access, and or if you decide so we can publish too. | |||

*Are there non-ABI impacting changes that we should do? E.g. marking classes as views/ranges, supporting new std types where necessary, etc. | |||

An appeal to record as many sessions as possible The Technical Product Management team in The Qt Company kindly asks to record as many sessions as possible. Unfortunately, there is a two-day workshop with another team on exactly the same days and no one from PM will be able to attend the live presentations. Last year, there were hesitations regarding recording. Please make it possible this year. If required recodings will be for internal use and will never be published for public access, and or if you decide so we can publish too.
