+Features, in approximate order of importance
+============================================
+
+### Complete-with-subset
+
+In cases where one of the Maker bots you select, either accidentally or by malicious
+intent, fails to complete the transaction negotiation process, pre-0.2.2, this would
+result in a failure that costs one utxo commitment (see the 0.2.0 notes for details).
+This can cause serious inconvenience for a Taker if it happens repeatedly, and this
+has been observed due to a number of non-responsive Makers in the pit.
+With this new feature, the transaction can still complete with a lower number of
+Makers (i.e. the ones that did respond).
+
+For example, with the default setting of minimum_makers=2 in the POLICY section of
+the joinmarket.cfg file, then if you request 5 counterparties, but only 3 respond,
+the transaction will go ahead with those 3 (and will still go ahead with as few as 2).
+You will get a slightly smaller privacy effect, but also pay less fees.
+In testing this has been seen to greatly reduce the chance of a transaction failure.
+You can disable this feature by setting minimum_makers=0.
+
+Do consider also using the -P feature for fine-grained counterparty selection,
+where that's possible. Note also that a future upgrade may offer even better
+"smart" counterparty selection.
+
+### Direct Send
+
+You can now send coins out of your Joinmarket wallet with the sendpayment.py script;
+use the option -N 0 (means 0 counterparties). All other syntax is the same, e.g. set
+amount 0 for sweeping. This sends coins from *1 mixdepth*; in Joinmarket we never
+send coins from multiple mixdepths at the same time, for privacy.
+
+This method of course does not connect to IRC, so it will be quicker, and of course
+cheaper than using a normal Joinmarket transaction. Before the transaction gets
+broadcast, it will be presented to you in raw and serialized form to check.
+
+Yield generators and other heavy users should be careful not to use this to send
+coins between mixdepths in the same wallet, as this could lead to unexpected and
+undesirable privacy outcomes.
+
+### Fast sync option
+
+When using Bitcoin Core, if the wallet has lots of used addresses, it results in a
+slow import and sync currently (the full context for this is a bit complex to explain).
+If you are *not* recovering a wallet or using a new Core instance, where you must
+start from scratch and *not* use this new feature, but are instead simply restarting
+your script, it's recommend to append the option --fast to *all* scripts (yieldgen,
+tumbler, sendpayment, wallet-tool). This uses a different, more efficient way of
+gathering the history of all the addresses. In tests it's been reported to reduce
+sync time by anything from 50-90% depending on your exact situation. If you are only
+an occasional user (e.g. using sendpayment) and have only few used addresses, it
+isn't important.
+
+### Logging levels
+
+By default, the logging messages *on the terminal* are now much reduced, corresponding
+to log level "INFO". The logging messages in the log file still contain everything
+("DEBUG" level).
+
+You can change the logging level on the terminal to one of INFO, WARNING, ERROR or
+DEBUG by setting the config variable console_log_level in section LOGGING. See the
+default joinmarket.cfg for reference.
+
+### Extra new default IRC server
+
+For better censorship resistance and redundancy it's recommended to use more than one
+"Message Channel" (at the moment only IRC is supported, but other messaging servers are
+easy to code, PRs welcome!). Some bots have already been using the agora IRC server
+(for donations, see: anarplex.net, address 12qvastA6FVod8L45Q3RPD8whbzvrZhxcQ).
+
+This extra IRC server is now added to the default config, so it's suggested that all
+participants use it as well as the existing CGAN. Note the rather ugly comma-separated
+lists; this format is required, with the same number of entries for *all* settings in
+the MESSAGING section.
+
+### Dump individual private key
+
+You can now use the method "dumpprivkey" to wallet-tool.py, in combination with the
+-H option, to dump the private key of one address without a full wallet sync.
