Step by step, hopefully it'll hit 12 months some day.
We recently updated the Top Search Queries data to take into account the average top position, we enabled programmatic download and we made sure you could still get all the queries that drive traffic to your site. Well, now itís time to give you more search queries data!
First, and most important, you can now see up to 90 days of historical data. If you click on the date picker in the top right of Search queries, you can go back three months instead of the previous 35 days....
Mod's note: Added article title and quote... and split to new thread.

Yes, I tried That Other Search Engine's wmt last night and got the infinite-script error-- though it seems to have displayed everything I wanted to see, even after I gave the script permission to stop trying.
Some experimenting on the google site reveals that the "With Change" option is only available up to 30 days. (Today in this time zone, that's March 29.) Otherwise it's grayed-out with a laconic "error" popup. Can't be because they don't have the data-- at least for the last 45 days + 45 days = 90 days. Can't be not enough room, since Clicks and Impressions could both go into the billions (US at least) before they get tight on space. And it isn't exactly a complicated calculation. Shrug.
