------------------------------------------------------------------- Wed Apr 15 15:49:52 UTC 2020 - Marketa Calabkova - Update to 0.3.0 * Provide both the requirements and their parents as exceptiondata for the ``ResolutionImpossible`` exception, via a ``causes`` attribute that replaces the previous ``requirements`` attribute. * Make resolver backtrack when none of the candidates requested for a package are able to resolve due to them requesting unworkable requirements, or a package has no candidates at all. Previously the resolver would give up on the spot. * Ensure the result returned by the resolver only contains candidates that are actually needed. This is done by tracing the graph after resolution completes, snipping nodes that don’t have a route to the root. ------------------------------------------------------------------- Sat Mar 16 17:27:15 UTC 2019 - Jan Engelhardt - Use noun phrase in descriptions. ------------------------------------------------------------------- Fri Mar 1 01:57:24 PM UTC 2019 - John Vandenberg - Initial spec for v0.2.2
