- added obs-service verify_file
- Version bump to 4.54.0
* fix error running getmail_fetch introduced in 4.53.0.
- Changes from 4.53.0
* fix plaintext version of docs not generated correctly.
* fix `getmail --fingerprint` not logging server TLS fingerprint correctly
with SimplePOP3SSLRetriever.
- Changes from 4.52.0
* add `ignore_header_shrinkage` parameter to Filter_external for users who
know it is normal for their particular filter to result in a smaller message
header than the source message, for example when the filter encapsulates
the original message in a simpler wrapper message.
* EXPERIMENTAL: when deleting a message from an IMAP mailbox, set the \Seen
flag in addition to the the \Deleted flag. This apparently prevents
the ever-innovatively-broken MSExchange from sending a spurious incorrect
disposition-notification message to the sender of the message. I do not
know if this will cause problems with other broken IMAP server
implementations; please send a report to the getmail-user's mailing list if
you see odd behaviour with this change.
* enable socket timeouts for IMAP SSL classes by default. They were disabled
in the code because they were incompatible with SSL in older versions of
Python. If you see problems with Python 2.6 or 2.7 now, please let me know.

- Changes from 4.51.0
