Yes, it has been blocked by the memory management work and the 0.2 release, both of which took a while, especially since most of the compiler had to be re-written from scratch (using an AST). The UI library was also re-written several times as we tried different approaches (native vs custom rendering).
The good news is that Volt was always being updated and made compilable, and a public beta is also coming this month.
I'm already using Volt as my primary Discord client (and my 8 GB RAM laptop thanks me for that, since I've freed 2 GB of RAM).
Here's a sneak peek:

Some layout issues, and Chinese/Japanese/emoji not being rendered correctly, but the latter has been fixed on a branch.
The moral of the story is: if you want to deliver a software application quickly, don't write a new language/stdlib/ui lib for it from scratch.
At least I got to create a cool language and share it with the world :)
