 * Very basic build system
     * Build is triggered by separate cron container
     * Packages build on cron container's system
+    * A HEAD request is used to determine whether a package should be rebuilt
+      or not
     * Hardcoded planning of builds
     * Builds are sequential
 * API for managing Git repositories to build
 * CLI to list, add & remove Git repos to build
 * Published packages on my Vieter instance
+* Support for multiple repositories
+* Support for multiple architectures per repository
 
 ## Fixed
 
 * Each package can now only have one version in the repository at once
   (required by Pacman)
+* Packages with unknown fields in .PKGINFO are now allowed
