What's going on?

The new updated AcornSSL with the updated HTTP fetcher is really aimed at native and homebrew RISC OS stuff, not for ported stuff.

Yes I meant to say for native build, depends on how you interpret porting. I read where someone encountered some heavy stuff inside packs or pack index’s when they did a conversion.
Would be a major job.
The online git repository is not going to support native filetypes -unless it is a RISC-OS git server, so filetypes and any other pecularities have got do be done anyway.
Having simplegit will be a good educational step for RISC OS users who have little experience with git. I have only used git clone on linux in the past. Probably wget or curl could do one off jobs equally.
The Phoenix browser actually allows one to see the github links, Netsurf makes it hard.

If NOOBS can find the RISC 5.26 ROM and firmware for the Pi can an SD card image be downloaded? If so, from what URL please?

I have uploaded Update10 which contains the !Boot directory and firmware to upgrade a Raspberry Pi model 1,2,3, A, A+, B and B+ etc. to RISC OS 5.26, see here.

The usual caveats apply when copying a !Boot image onto your existing boot setup. Check the filer options are set to Verbose and Force and that Newer is not ticked. Keep a backup copy of your existing boot but do not copy the file Loader, instead create a directory in your backup called ‘Loader’ and copy the contents of Loader not the file.

Any news on the git migration?
Thanks!
