I had a great week. I fixed a lot of bugs, and I managed to finish the first part of my new autocomplete tags cache. I still need to test it on a real-world database, and the cache does not yet cover all search domains, but in general it seems to be producing autocomplete results for a 6,000 file/20m mappings db in about 40-100ms. I am obviously extremely pleased. The cache takes a bit of CPU to initialise and sync with an existing service, so I expect the update to take a few minutes, possibly longer.
Absent any problems in my extended testing, the release should be as normal tomorrow.
