some good news and bad news(if you haven't already heard).
Good News: HackMii installerv0.5 is here
It has a new exploit to enable (un-)installation of all components on fully updated Wiis.
Also fixes hangs on some setups (they’re all related to retarded IOS patches).
also comes with the following(credit to HackMii blog and WiiBrew):
BootMii beta 4 (v1.1):
Properly write the keys to nand.bin.
This fixes the “NAND dump is from another Wii” issue on restoring beta 3 backups. If you don’t know how to fix those dumps, you have to backup the NAND again. Dumps from all other versions are not affected.
The Homebrew Channel v1.0.5:
Faster startup.
Prefer boot.elf over boot.dol when launching apps.
New shiny fonts, tweaked to the last subpixel.
Widescreen support.
If your Wii is set to 16:9 in the system menu options, HBC won’t strech the picture like it did on older versions. Unfortunately the fonts might look a little weird then, it really depends on the used display unit. Blame the lack of true widescreen support on the Wii for that.
Grid view.
Hit 2/Y while browsing applications to switch between the old and the new view. This shows 4 columns on 16:9 setups, 4:3 users only get 3.
Device hot-plugging.
You can remove and insert devices (front SD slot, USB mass storage, and SDGecko in both slots) at all times now without reloading HBC.
To change to another device, hit 1/X to bring up a simple option dialog.
Application sort order.
You can now choose how to sort the shown entries. Current options: either by the name or by the release date.
Note that for the latter sort order a valid release_date tag has to be present in the meta.xml file.
Again, hit 1/X for the options dialog to set this.
wiiload overhaul.
On-the-fly compression: Uploaded files are automatically compressed on PC side: This makes it way faster, especially on bigger files. ScummVM, anyone?
Improved USBGecko support: Faster uploads, and you don’t have to stop reading debug messages from the device while uploading files.
libftdi support: Because ftdi-sio fails, especially on OSX.
Note: Because of these improvements, older wiiload version and 3rd party upload clients are incompatible. Use the bundled v0.5, binaries and source code are included.
Basic application management.
To add apps: Just wiiload a ZIP archive, it will then get extracted to the active device. The ZIP file must be structured in a certain way, check this description for the details. To delete apps: There’s a new button on the application dialog.
To delete apps: There’s a new button on the application dialog.
DVDX 2.0:
Allow PPC side hardware access.
Also known as the magic HW_AHBPROT register.
TMD version bumped to 2, in case anyone needs to check for e.g. HW_AHBPROT.

http://bootmii.org/downloadbad news: i still advise not to update to 4.2. (Wii Brew said so) (i'm only restating this for any non-members of this fourm who are reading this)
According to bushing, "The [boot 2 update] code [from Ninty] is so buggy that we decided to write our own for the HackMii installer." There are some people who are bricking their Wii as a result of doing a standard update, whether or not they had hacks before they updated. It is therefore highly recommended that you at the very least do not upgrade through Nintendo.
plus i learned from the Gecko fourms that Gecko 1.9.2 will not load on 4.2
so i suggest using the online update feature on your homebrew channel to upgrade to 1.0.5.
again DO NOT UPDATE YOUR WII THROUGH NINTENDO!!!!!!!!!!!!!
YOU'VE BEEN WARNED!
