For those following really closely, we will be announcing this in the next day or so. The team will be ensuring that the VSCode extension can correctly download the pre-compiled release and things seem fine.

Please check out https://expert-lsp.org/news in the coming days for a full announcement that includes expectations for this release. We want people to be excited, but we also want them to be aware that they may still run into bugs. We want to know about these bugs, so please create issues and work with us to solve them.
