A polite note for pedants and download aggregators, since I am starting to get spurious mail and bug reports about this: the availability of this build doesn't mean it's generally available; this is for last-minute RC testing. Our release dates correspond broadly with Mozilla's and version alerts will not be updated until Monday.
10.0.5 also marks the general availability of language pack installers, for stable branch users only. Many thanks to Chris and our localizers! If you have not tested them yet, please choose German, French or Polish from the Downloads tab, and report your results. The installers will work on any 10.x version of TenFourFox from 10.0.3 on up; they are distributed as actual installers, not as standard Firefox .xpis. Do not use them with the unstable versions.
The port for 14 will begin with beta 8 (14 betas will start with 5 to harmonize numbering with Fennec). For now, 10.0.5 release notes and official arch builds follow; if there are no issues these will finalize on Monday:
