1413 is now available. Please upgrade to 1413 and not 1412. Due to a mistake on 
my part 1412 included some, but not all, of the recent work on the datastore. I 
had thought it didn't include any of it. So nodes with "shrink on startup" 
enabled could break and be unable to start if a shrink happened to be in 
progress. This is fixed in 1413.
Changes (including parts in 1412 not mentioned in the previous changelog):
- Significant disk I/O optimisation to the datastore: The datastore slot 
filters (*.slotfilter), tiny files that help the store to check whether we have 
a particular key and where to put it if we don't, are now written every 5 
minutes (configurable) rather than immediately on a write. This saves 
approximately one seek per written block, which could be several seeks per 
second. The writes every 5 minutes should not be disruptive, but please let me 
know if disk I/O appears to be heavier or lighter with this build.
- Minor changes to a couple of strings related to darknet.
- Add some comments to clarify the code.

Sorry!
