Release D 2.094.0

Glad to announce D 2.094.0, ♥ to the 49 contributors. This release comes with faster compiler binaries (built with ldc), direct git dependencies in dub, better type checking of vectors, and improved template instantiation diagnostics. http://dlang.org/download.html http://dlang.org/changelog/2.094.0.html -Martin

I'd use the delay as an opportunity to shift the bi-monthly releases to even months (to avoid the beta during the holiday season). https://github.com/dlang/dlang.org/pull/2860

I have a VisualD project that build successfully in release but fail in debug without any error message - it fails in "semantic3" step on one of the module.

Only the version build during continuous have assert on since a few weeks [1]. The PR that should have allowed the same in the official release [2] has been closed by error, hence the changelog lead to a wrong idea about the current state of assert in the compiler itself.

But it's a preview because people tend to use "in" because it was shorter than "const" so many code base are poisoned with this misuse (although in plenty of case the new semantics probably dont cause bugs...)

Author here. The most complete way to know would be to read the changelog: https://dlang.org/changelog/2.094.0.html#preview-in
The TL;DR is that, in addition to `const scope`, `in` now automatically behaves as `ref` when "it makes sense" such as large value types or presence of destructors / postblit (more details in the changelog!) and will accept rvalues, unlike other ref parameters.
