Conary 2.0.46 is a maintenance release.

• If python-keyutils is available, cvc will try to interact with the user's session keyring. (CNY-3190)
• Conary now uses xz in preference to unlzma to decompress lzma data. (CNY-3194)
• A new function, parseChangeSpec, that parses a single trove update specification such as name=ver1[flv1]--ver2[flv2], was added to cmdline.py. (CNY-3197)

• The code path leading to getChangeSet was reworked to use significantly fewer repository calls, resulting in a massive speedup for uncached, large requests.

• PGP passphrases, required for signing troves, are now fetched using a callback. (CNY-3189)
• Repositories running on postgresql can properly handle queries for labels sharing the hostname portion. (CNY-3192)
• The sha1 for files in a repository could be improperly left as NULL for some cases involving shadows. This has been fixed, and migrating existing repositories to version 17.3 will fix existing missing sha1 checksums.
• Group pre-execution scripts now run exactly before any package that is part of the group. Previously, pre-execution scripts were run at the very beginning of the update, where the probability of their interpreter not being installed was high, especially for pre-install scripts. (CNY-2705)
• Group pre-execution scripts no longer unnecessarily fetch information they already have from the repository. (CNY-3196)
• Password information for XMLRPC server URLs is now hidden in tracebacks. (CNY-3198)
