Conary 2.0.22 is a maintenance release.

• The loadSuperClass and loadInstalled methods now returns the loaded recipe class so that the loaded class can be referenced anonymously. This makes factories more flexible. (CNY-2900)
• The addPatch source action now takes a "filter" keyword argument that provides a command line that can modify the patch; for example, by calling the filterdiff program. (CNY-2874)
• Builds previously failed in some circumstances when Conary discovered no need only for :runtime components listed in buildRequires. This has been fixed, and error reporting improved for similar classes of bugs in the future. (CNY-2904)

• The new boolean conaryrc option downloadFirst has been added to instruct Conary to download all required changesets from the repository before proceeding to update steps. (CNY-2808)

• Conary 2.0.20 introduced a bug adding dependencies to postgres-based repositories; this has been resolved.
• Starting in 2.0.20, dependency resolution started locking the database unnecessarily. This affected rmake dependency resolution, and is now resolved.
• Mirroring code now correctly detects when access control changes in the source repository require the generation of absolute changesets for mirroring. (CNY-2888)
• A permission check error for users that only have trove access entitlements has been fixed. (CNY-2761)
• A problem with the autoLoadRecipes config option has been fixed. (CNY-2909)
• A permission check problem when trove names are used as trove patterns in ACLs has been fixed. (CNY-2913)
