That's fine, I might have an idea who have been saying so, but that statement has never been the consensus even among the Glance core team. In fct you would be well aware of this if you did follow the pretty colorful discussion around glance spec.
We also have not had any intention to provide versioned images as that would break our immutability promise (the image data will stay consistent to the id through the image life once it has turned to "active" state, as in you will always get same data, if any, out when you do image-download to specific image ID). So no I don't see us recombine these projects in any foreseeable future and I'd be perfectly fine if some future day Glance becomes obsolete because Glare does it's job better. What comes to the reconsidering the stance, I'd love to see the community being able to work out the issues and do the development together. On the other hand I've been telling to Mike for quite a while that they really should consider spinning Glare off. In reality this will be much better for the Glare future development, the teams who have been waiting desperately for last couple of cycles to get consuming it and it will also make bit of room for Glance community to fully focus on the things that are important to the Glance consumers rather than trying to divide the attention. - Erno On Thu, Aug 4, 2016 at 8:20 PM, Fox, Kevin M <[email protected]> wrote: > I disagree.
