Ubuntu 17.10 was open for development since last Friday, but because there wasn’t anyone to send the regular mailing list announcement to inform developers about this important fact, only a few knew about it. However, we’re informing you today that Artful is officially open with two major packaging toolchain changes. According to Adam Conrad, the first change is that ddebs will be generated using the upstream debhelper code, and the second one is for the dpkg package manager, which apparently will now produce .buildinfo files by default for all uploads, including source builds.
