It apparently escaped my attention that LibreOffice dropped support for Tiger and Leopard, and hence PowerPC, sometime about six months ago. What, doesn't anyone tell me anything around here!
Anyway, Tiger users can always dual boot Linux for new versions, but here's the good news. Someone stepped in and started a PowerPC port of LibreOffice for Leopard. That's right, Leopard users can download the latest version at OSU Open Source Labs. It appears the maintainer is very active and knowledgeable, having sent patches upstream, and he even uploaded screenshots for the eyes of the non-believers.
The last official release that supports Tiger is at the LibreOffice archives.
Meanwhile, I've been taking TenFourFox 29 beta out for a spin. It hasn't suffered from the bug from hell that has affected Firefox 29 on PowerPC Linux. I'm sure everyone involved would appreciate your contribution if you have any knowledge to lend. But back to TenFourFox, the new GUI is zippier than ever. Page rendering is fast even though I'm running on a separate profile with no script or ad blocking add-ons. If Mr. Floodgap keeps this up, it'll end up the goto browser for Snow Leopard.
