Latest CI builds of branch master, published by the Azure Pipelines, Travis (Linux AArch64) and Cirrus (FreeBSD) CI services. These packages (except the FreeBSD one), unlike release packages, feature enabled LLVM and LDC assertions, so expect a slower compilation speed.
Don't trust the release date above, that's when this GitHub release was initiated. The same goes for tag/commit/source downloads.
