The update is a first step in addressing the infamous problems introduced in the previous v4.6 over-the-air-download in January. However, although it may offer some improvement, it does not unfortunately fix all the problems reported. Owners of boxes currently running v4.6 are advised to complete the update. Whereas those running v4.1 and earlier should think twice - it is recommended to avoid the v4.8 update. There will be a new version soon to address all the troubles of v4.6 (and v4.8).
