There were two minor updates in code version H.21.1:
- We improved ClickMap data accuracy in cases where multi-suite tagging is in use.
- We improved the way URL encoding and decoding occur in the case of multi-byte characters, in order to work around a bug in older browser versions in the Android OS.
So, how do you know whether you should consider upgrading to H.21.1? You should consider upgrading if:
- You use multi-suite tagging (see explanation here) and also rely heavily on ClickMap.
- You have a mobile site that uses multi-byte characters and receives traffic from Android devices.
