**The future of Exiv2**

What happens to Exiv2 in future is a matter for the community. I returned from retirement to deal with Exiv2 v0.27.3 as progress on v0.28 is glacial.

I am writing a book called **Image Metadata _and_ Exiv2 Architecture**.
https://clanmills.com/exiv2/book/ https://clanmills.com/exiv2/book/IMaEA.pdf

I will be 70 in January and will retire after LGM 2021. I would like to give a talk at LGM in Rennes in May 2021 and run an afternoon work-shop to discuss the book.

I hope the Community at LGM 2021 will discuss the future of Exiv2.
