The new release switches to vibe-core by default* and compiles on the freshly released DMD 2.079.0. It needs to be used together with the latest vibe-core pre-release, because instead of std.experimental.allocator, which is still undergoing frequent API changes, the forked semi-stable variant stdx.allocator is being used, and both libraries need to match up in that regard. This version contains a fix in URLRouter that can heavily reduce the memory usage of processes that define many routes.
