EDIT: this build has been switched from beta to release. No need to re-download it if you've already downloaded it.
The build 282.3 is available.
The main changes compared with 282.1 are fixes in the HTML5 sounds and a fix in the iOS Store object (hopefully the good one). More details in the change log.
No changes in the Android/Flash exporters, nor in the iOS exporter except for the iOS Store fix, Fernando and Anders will post beta versions for each exporter kater.
