This is scheduled regular release of aptly (a bit late according to planned to schedule).
Acquire-By-Hash
aptly supports by hash layout for published repositories (https://wiki.ubuntu.com/AptByHash). This fixes a race when apt is downloading Release file while it's being updated to match new package indexes.
Acquire-By-Hash mode is backwards compatible with clients which do not support it. Feature should be enabled when repo or snapshot is first published, subsequent operations (update, switch) would have acquire-by-hash mode enabled.
Example:
aptly publish snapshot -acquire-by-hash snap-repo-20171205
Thanks to @sliverc and @neolynx for the implementation of this new feature (#664, #381, #551).
Dependency Resolution
Several significant improvements were made to aptly internal dependency resolution engine. This specifically affects -dep-follow-all-variants, but there are some other changes improving compatibility.
With 1.2.0 filters which have dependency resolution enabled might produce a bit different results (which should be more correct anyway).
