This release contains updates and one new feature.
The tracking code can now send much larger tracking beacons. Traditionally, beacons have been sent via HTTP GET requests, which are limited to 2048 characters by some browsers and proxies. Requests over this limit were dropped and the data never reached Google Analytics. Starting with this release, requests longer than 2048 characters will be sent via HTTP POST, which has no such limit. The tracking code will now support beacons up to 8192 characters.
Adobe should follow suit - seems like a no-brainer if the technology is there. This would reduce the need for Dynamic Variables as well!
