+%changelog
+* Sun Jun 30 2013 Bob Mottram (4096 bits) <bob@robotics.uk.to> - 0.3.4-1
+- Switched addr, msg, broadcast, and getpubkey message types
+  to 8 byte time. Last remaining type is pubkey.
+- Added tooltips to show the full subject of messages
+- Added Maximum Acceptable Difficulty fields in the settings
+- Send out pubkey immediately after generating deterministic
+  addresses rather than waiting for a request
+
+* Sat Jun 29 2013 Bob Mottram (4096 bits) <bob@robotics.uk.to> - 0.3.3-1
+- Remove inbox item from GUI when using API command trashMessage
+- Add missing trailing semicolons to pybitmessage.desktop
+- Ensure $(DESTDIR)/usr/bin exists
+- Update Makefile to correct sandbox violations when built
+  via Portage (Gentoo)
+- Fix message authentication bug
+
+* Fri Jun 28 2013 Bob Mottram (4096 bits) <bob@robotics.uk.to> - 0.3.211-1
+- Removed multi-core proof of work
+  as the multiprocessing module does not work well with
+  pyinstaller's --onefile option.
+
+* Mon Jun 03 2013 Bob Mottram (4096 bits) <bob@robotics.uk.to> - 0.3.2-1
+- Bugfix: Remove remaining references to the old myapp.trayIcon
+- Refactored message status-related code. API function getStatus
+  now returns one of these strings: notfound, msgqueued,
+  broadcastqueued, broadcastsent, doingpubkeypow, awaitingpubkey,
+  doingmsgpow, msgsent, or ackreceived
+- Moved proof of work to low-priority multi-threaded child
+  processes
+- Added menu option to delete all trashed messages
+- Added inv flooding attack mitigation
+- On Linux, when selecting Show Bitmessage, do not maximize
+  automatically
+- Store tray icons in bitmessage_icons_rc.py
+
+* Sat May 25 2013 Jonathan Warren (4096 bits) <jonathan@bitmessage.org> - 0.3.1-1
+- Added new API commands: getDeterministicAddress,
+  addSubscription, deleteSubscription
+- TCP Connection timeout for non-fully-established connections
+  now 20 seconds
+- Don't update the time we last communicated with a node unless
+  the connection is fully established. This will allow us to
+  forget about active but non-Bitmessage nodes which have made
+  it into our knownNodes file.
+- Prevent incoming connection flooding from crashing
+  singleListener thread. Client will now only accept one
+  connection per remote node IP
+- Bugfix: Worker thread crashed when doing a POW to send out
+  a v2 pubkey (bug introduced in 0.3.0)
+- Wrap all sock.shutdown functions in error handlers
+- Put all 'commit' commands within SQLLocks
+- Bugfix: If address book label is blank, Bitmessage wouldn't
+  show message (bug introduced in 0.3.0)
+- Messaging menu item selects the oldest unread message
+- Standardize on 'Quit' rather than 'Exit'
+- [OSX] Try to seek homebrew installation of OpenSSL
+- Prevent multiple instances of the application from running
+- Show 'Connected' or 'Connection Lost' indicators
+- Use only 9 half-open connections on Windows but 32 for
+  everyone else
+- Added appIndicator (a more functional tray icon) and Ubuntu
+  Messaging Menu integration
+- Changed Debian install directory and run script name based
+  on Github issue #135
+
+* Tue May 6 2013 Bob Mottram (4096 bits) <bob@sluggish.dyndns.org> - 0.3.0-1
+- Added new API function: getStatus
+- Added error-handling around all sock.sendall() functions
+  in the receiveData thread so that if there is a problem
+  sending data, the threads will close gracefully
+- Abandoned and removed the connectionsCount data structure;
+  use the connectedHostsList instead because it has proved to be
+  more accurate than trying to maintain the connectionsCount
+- Added daemon mode. All UI code moved into a module and many
+  shared objects moved into shared.py
+- Truncate display of very long messages to avoid freezing the UI
+- Added encrypted broadcasts for v3 addresses or v2 addresses
+  after 2013-05-28 10:00 UTC
+- No longer self.sock.close() from within receiveDataThreads,
+  let the sendDataThreads do it
+- Swapped out the v2 announcements subscription address for a v3
+  announcements subscription address
+- Vacuum the messages.dat file once a month: will greatly reduce the file size
+- Added a settings table in message.dat
+- Implemented v3 addresses:
+  pubkey messages must now include two var_ints: nonce_trials_per_byte
+  and extra_bytes, and also be signed. When sending a message to a v3
+  address, the sender must use these values in calculating its POW or
+  else the message will not be accepted by the receiver.
+- Display a privacy warning when selecting 'Send Broadcast from this address'
+- Added gitignore file
+- Added code in preparation for a switch from 32-bit time to 64-bit time.
+  Nodes will now advertise themselves as using protocol version 2.
+- Don't necessarily delete entries from the inventory after 2.5 days;
+  leave pubkeys there for 28 days so that we don't process the same ones
+  many times throughout a month. This was causing the 'pubkeys processed'
+  indicator on the 'Network Status' tab to not accurately reflect the
+  number of truly new addresses on the network.
+- Use 32 threads for outgoing connections in order to connect quickly
+- Fix typo when calling os.environ in the sys.platform=='darwin' case
+- Allow the cancelling of a message which is in the process of being
+  sent by trashing it then restarting Bitmessage
+- Bug fix: can't delete address from address book
+
+* Tue Apr 9 2013 Bob Mottram (4096 bits) <bob@sluggish.dyndns.org> - 0.2.8-1
+- Fixed Ubuntu & OS X issue:
+  Bitmessage wouldn't receive any objects from peers after restart.
+- Inventory flush to disk when exiting program now vastly faster.
+- Fixed address generation bug (kept Bitmessage from restarting).
+- Improve deserialization of messages
+  before processing (a 'best practice').
+- Change to help Macs find OpenSSL the way Unix systems find it.
+- Do not share or accept IPs which are in the private IP ranges.
+- Added time-fuzzing
+  to the embedded time in pubkey and getpubkey messages.
+- Added a knownNodes lock
+  to prevent an exception from sometimes occurring when saving
+  the data-structure to disk.
+- Show unread messages in bold
+  and do not display new messages automatically.
+- Support selecting multiple items
+  in the inbox, sent box, and address book.
+- Use delete key to trash Inbox or Sent messages.
+- Display richtext(HTML) messages
+  from senders in address book or subscriptions (although not
+  pseudo-mailing-lists; use new right-click option).
+- Trim spaces
+  from the beginning and end of addresses when adding to
+  address book, subscriptions, and blacklist.
+- Improved the display of the time for foreign language users.
+
+* Tue Apr 1 2013 Bob Mottram (4096 bits) <bob@sluggish.dyndns.org> - 0.2.7-1
+- Added debian packaging
+- Script to generate debian packages
+- SVG icon for Gnome shell, etc
+- Source moved int src directory for debian standards compatibility
+- Trailing carriage return on COPYING LICENSE and README.md

+pybitmessage: pybitmessage (Send encrypted messages)
+pybitmessage:
+pybitmessage: Bitmessage is a P2P communications protocol used to send
+pybitmessage: encrypted messages to another person or to many subscribers. It
+pybitmessage: is decentralized and trustless, meaning that you need-not
+pybitmessage: inherently trust any entities like root certificate authorities.
+pybitmessage: It uses strong authentication which means that the sender of a
+pybitmessage: message cannot be spoofed, and it aims to hide "non-content"
+pybitmessage: data, like the sender and receiver of messages, from passive
+pybitmessage: eavesdroppers like those running warrantless wiretapping
+pybitmessage: programs.

+Levels:
+    DEBUG       Detailed information, typically of interest only when diagnosing problems.
+    INFO        Confirmation that things are working as expected.
+    WARNING     An indication that something unexpected happened, or indicative of some problem in the
+                near future (e.g. ‘disk space low’). The software is still working as expected.
+    ERROR       Due to a more serious problem, the software has not been able to perform some function.
+    CRITICAL    A serious error, indicating that the program itself may be unable to continue running.
+
+There are three loggers: `console_only`, `file_only` and `both`.
+
+Use: `from debug import logger` to import this facility into whatever module you wish to log messages from.
+     Logging is thread-safe so you don't have to worry about locks, just import and log.
