And another ‘behind-the-scenes’ update which is a big change technically but shouldn’t affect users much.

Potlatch itself now keeps track of nodes you’ve deleted. Previously, when you deleted some nodes from a way using Potlatch and then saved the way, Potlatch would just say to the server “here’s the new way with these nodes”. The server would then work out which nodes were in the way beforehand, and delete any that weren’t used.

Now, Potlatch says “here’s the new version of the way, and by the way could you delete these nodes please?”. So Potlatch is doing more and the server is doing less.

It should hopefully make things a little faster, as there’s now less for the server to do every time you write a way. But as ever there might be teething problems, so if you get an error message, do report it!

Now live (thanks Tom, wherever you are!). Nothing major has changed, just a big bunch of small bugfixes and performance enhancements.

Potlatch 0.10c is now live.

Changes include:

  • little floating alerts that go beep: these show up if, for example, you try to merge two ways with differing tags, or that don’t share a point
  • locked nodes show up red: typically after importing a GPX with waypoints
  • performance improvements
  • a few new ‘advanced user’ features:
    • press K to lock/unlock a way or node
    • press M to maximise/minimise the editor window
    • press S to add a source= tag based on the current background (Yahoo/NPE)
  • major bug fixed that caused duplicate nodes when the server was slow
  • latest translation update
  • and various other bugfixes

Some really exciting stuff coming up in the next few months… more soon.

…and hopefully there’s something for everyone.
If you’re a map editor, the biggest change is that tagged nodes in ways are now indicated with a little black circle – so you can see traffic lights, mini-roundabouts, railway stations, gates etc. etc.
If you’re a non-English speaker, Potlatch might now appear in your language. Lots of people have helped out by supplying translations on the wiki – feel free to supply more. Any changes you make will show up next time I commit a Potlatch change.
If you’re a Rails port hacker – amf_controller now speaks your language. :)
User interface changes include a more prominent “loading ways” animation at the top right. You can also call Potlatch with &way=12345 or &node=56789 in the query string – added specially for ito!’s excellent OSM Mapper tool.
There’ve been a number of changes under the hood, too, such as a major rewrite of Potlatch’s node handling, and all projection now being done in Potlatch itself rather than on the server. I’d expect a handful of little issues to crop up – as ever, you can report them on trac. Thanks to all those who’ve helped in one way or another.
