Revise GVRS file format, is backward compatibility required? #27

Closed gwlucastrig closed 1 year ago

gwlucastrig commented 1 year ago

I am considering a series of changes to clean up the file format for the Gridfour Virtual Raster Store (GVRS, formerly G93). If I make these changes, they will break backward compatibility with existing files. I am trying to assess the impact this change will have on existing users.

As far as I know, GVRS has not yet established a user base. While this situation is a personal disappointment, it has the advantage that I can proceed with format changes without a negative impact on anyone else's work (something about which I am very concerned).

If you have been working with GVRS files, please let me know so that the Gridfour project can continue to support you.

Thanks,

Gary

GVRS updated to 1.0.4. The API will support pre-1.0.4 versions on a read-only basis. This feature may be retired in future releases.

Version 1.0.4 is considered a stable version of the GVRS format.
