You say they're planning to add a feature in the next release, but what you linked to is merely an uncompleted to-do item for creating a UI switch to toggle a feature that hasn't been written yet. I think you win the prize for the most ridiculous exaggeration in this thread. Unless you can link to something that actually comes anywhere close to supporting your claim, you're just recklessly lying.
The linked Issue #8553 is "just" about creating a toggle for GPU acceleration. It's blocked by Issue #8552 [0], which is the actual Issue about the acceleration and originally belonged to Milestone "Release 4.3". It seems to have been removed later, which I didn't expect or know about. Accusation of lying was completely unnecessary in your comment.
Moreover, the Milestone was removed not because they changed their mind about the Release but for other reasons [1].
Ok, so your [0] shows that the real work has barely been started. The only indication it was ever planned for the next release was a misunderstanding on your part about the meaning of a tag that was applied to the issue for less than one day last fall, and they've stopped tagging issues with milestones to prevent such misunderstandings in the future. It still looks to me like your exaggerated claim was grounded in little more than wishful thinking.
Am I missing something? This is to add a toggle button and the developers say they are blocked because GPU acceleration feature doesn't exist so the button wouldn't be able to do anything.
