Changes in version 0.100:
- The bridge authenticates users to Koji based on the CN of their certificate,
  not based on the user name defined on the server.
- Use 'topurl' instead of 'pkgurl' from Koji configuration, following the change
  in Koji 1.7.
- Add support for restricting access to individual Koji instances to specific
  FAS groups.
- Changes to connection termination: end request processing even if something
  (a firewall) swallows FIN packets.
- Reject the nonsensical combination of (sigul sign-rpm{,s} --koji-only -o ...),
  and reject signing of empty RPM files.
- Log RPM output on signing failure.
- Make sure to always close sockets in the bridge.
- Miscellaneous cleanups.

Changes in version 0.99:
- Support for multiple koji instances in the client and bridge: new client
  parameter --koji-instance, client and bridge option koji-instances.

Changes in version 0.98:
- Now uses sqlalchemy 0.5 (e.g. RHEL6)
- New operation 'sign-rpms', up to 50% faster.
  New bridge and server options max-rpms-payload-size.
- Server option gnupg-key-usage has changed default to "sign" (removing
  "encrypt"), to work with DSA keys.  sigul does not provide decryption, so
  signing is all that is necessary anyway.
- New client parameter --user-name
- New brige option koji-config, patch by Dan Horák.
- New server option signing-timeout
- New sigul_server_add_admin parameters --batch , --name
- In sigul_setup_client, no longer ask for a known password, recognize attempts
  to overwrite an existing certificate.
- Fixed closing of sockets, in particular to avoid random "connection reset"
  errors
- Other minor bug fixes
- Added a basic test suite (not testing FAS/koji integration)
- Work with post-RHEL5 URLGrabber

Changes in version 0.97:
- Proxy authenticate clients in the bridge.
- Log the client's identity in the server as well.
- Don't cache RPM information between signing requests.
- Fix signing of source RPMs.
- Fix signing of RPMs with non-null epoch.
- Various minor bug fixes.

Changes in version 0.96:
- Add support storing for RSA and PGPv4 signatures into Koji.
- Fix pid file removal in the bridge.
- Fix waiting on clients in the bridge when forwarding the inner stream.
- Make sure a RPM is written to a file before attempting to parse the file.
- Various error handling bug fixes and enhancements.

Changes in version 0.95:
- Fix authentication failures on connections with some mixed Python versions.
- Allow running with modified python-nss-0.1 in addition to unmodified 0.4.

Changes in version 0.94:
- Update to run with python-nss 0.4 (local modifications are no longer required,
  won't work with older versions of python-nss).

Changes in version 0.93:
- New command "sigul import-key".
- Fixed FAS authentication support with new python-fedora.

Changes in version 0.92:
- Added --v3-signature to "sigul sign-rpm", rpm doesn't recognize v4 RSA
  signatures.
- SIGTERM no longer causes a backtrace.

Changes in version 0.91:
- Modified sigul to run on RHEL5.
- Enhanced handling of unexpected EOF in the client.
- Modified README not to recommend copying the CA private key around.
