Re: WRT54G; What is latest version of firmware ?

History.

Linksys released the 4.30 firmwares for the WRT54GL model which are compatible with the WRT54Gv1-v4.

I guess some people were confused to see WRT54GL on the web interface of the router although they had a WRT54G.

Thus they re-released the firmware for the WRT54Gv1-v4 with 4.21.* showing the correct model name.

You should be able to use either firmware for either router. If you check the release notes of 4.21.* and 4.30.* you'll notice that they basically have the identical history of changes. 4.30 is now a little bit more advanced if you look on the WRT54GL downloads page.

Re: WRT54G; What is latest version of firmware ?

I dont think so that using the firmware version 4.21.1 will cause any problem ...... as you said that it is not mentioned under released notes.......
