The official update used to seem unsafe, but this isn't an issue any more.SDHC card support, Wii shop access, ability to run channels that were previously saved to SD/SDHC and a fix for a bug in Wii Sports Resort. Some bug fixes in The Conduit multiplayer and a slightly faster startup time. If you are very cautious, you can remove all risk using PART 1 of the Upgrade method first. Wii is the first of these games and most future games do too. The first upgrades you to 4.1, the second upgrades your boot2.For these games, use the new installation methods of the IOSes or use the Avoid Disc Updates method.
Instructions for doing so safely are on the Upgrade page.
However, only perform this if you absolutely want the newer features.
Many games perform simple IOS updates to the official IOSes and do not upgrade your firmware. To be perfectly safe, you should only run the updates on these discs after performing PART 1 of the Upgrade page.
Games with 4.2 and 4.3 updates (Super Mario Galaxy 2, Lego Harry Potter: Years 1-4, etc.) will also ask you to update even if you already on the firmware version of the update as they are trying to delete d2x and Hermes' IOS222/223.

The official update is very slightly unsafe (Equally as unsafe as if you had homebrew), although you can remove the risk using PART 1 of the Upgrade method. It is the boot2 upgrade which is slightly dangerous, but it can be avoided by PART 1 of the Upgrade method.
