git-annex (5.20140402) unstable; urgency=medium
* unannex, uninit: Avoid committing after every file is unannexed, for massive speedup. * --notify-finish switch will cause desktop notifications after each file upload/download/drop completes (using the dbus Desktop Notifications Specification) * --notify-start switch will show desktop notifications when each file upload/download starts. * webapp: Automatically install Nautilus integration scripts to get and drop files. * tahoe: Pass -d parameter before subcommand; putting it after the subcommand no longer works with tahoe-lafs version 1.10. (Thanks, Alberto Berti) * forget --drop-dead: Avoid removing the dead remote from the trust.log, so that if git remotes for it still exist anywhere, git annex info will still know it's dead and not show it. * git-annex-shell: Make configlist automatically initialize a remote git repository, as long as a git-annex branch has been pushed to it, to simplify setup of remote git repositories, including via gitolite. * add --include-dotfiles: New option, perhaps useful for backups. * Version 5.20140227 broke creation of glacier repositories, not including the datacenter and vault in their configuration. This bug is fixed, but glacier repositories set up with the broken version of git-annex need to have the datacenter and vault set in order to be usable. This can be done using git annex enableremote to add the missing settings. For details, see http://git-annex.branchable.com/bugs/problems_with_glacier/ * Added required content configuration. * assistant: Improve ssh authorized keys line generated in local pairing or for a remote ssh server to set environment variables in an alternative way that works with the non-POSIX fish shell, as well as POSIX shells. # imported from the archive

+### Please describe the problem.
+git-annex refuses to use revoked GPG keys. This may be understandable for the initial remote setup, but it hit me when I tried to add a new key to a remote. The previous key has been revoked (because it has been superseded by the new one), and git-annex refused to reinvoke the shared key with both keys because one of them was revoked.
+
+Given the encryption model does not allow key replacement, it should not refuse to reencrypt using a revoked key. Maybe using `--expert` would help.
+
+### What steps will reproduce the problem?
+Encrypt a special remote with a key K1. Revoke key K1. Try to add key K2 with enableremote. git-annex will refuse to encrypt the shared key with the revoked one.
+
+### What version of git-annex are you using? On what operating system?
+git-annex version: 4.20130802-g1452ac3
+
+### Please provide any additional information below.
