Thanks.
Do you plan to release updated RxDOS binaries?

I don't currently have access to any hosting. If Robert wants to upload something, I could prepare an archive.

It's still some way from being usable though; filesystem redirector support is entirely missing, initialisation doesn't relocate data structures yet (they sit at the top of low memory), some initialisation structures aren't deallocated yet (also at top of low memory), [Rx]CONFIG.SYS processing doesn't detect and report errors properly, RxCMD doesn't swap out its code segment (and it generally receives less attention on my part), an init PSP isn't used yet, sector sizes other than 512 bytes aren't properly supported yet, cluster sizes are only supported up to 32768 bytes.

Some things that I already did: DOSCODE to HMA, to UMA, or to LMA relocation, DOSDATA to UMA or LMA relocation, UMB linking and usage, setting up the CDS with 32 entries early on, full RPL/RPLOADER support, full LBA32 support, booting as a single-file kernel.

doesn't bitbucket providing space for binaries?

Well spotted! I didn't know that yet. I'll upload an archive once I finish the 7.24 release, which will likely be before 2018-07-07.

No, I haven't done as much as I'd like yet. If I get back to development I'll probably add a feature or two and then release 7.24.
