It's Junos 9.3, latest Release is file junos-jseries-9.3R4.4-domestic.tgz
(they may also have service (S) releases of 9.3 with bug fixes available via JTAC).

9.3 because of? (flow mode? Memory? Technical Bulletin?) I wasn't aware of any particular restrictions on the J2300 preventing it from running any recent Junos release (e.g. 11.1) - but if there is one, we can get a warning up on the download page.

According to my knowledge, Junos "Enhanced services" (junos-jsr*) has never been supported on older J-series (J2300, 4300, 6300). And 9.3 is just the last packet-based junos (junos-jseries*) for J-series that exists.
I don't have TB info but compating the following links, you can see Jx300 is not considered as a supported platform in 9.4:
I've also seen some info (can't recall where) that junos-jsr actually will work on J2300, but it is not supported.

Dropping platform support is a Big Deal which is why I asked. I just checked with JTAC - J2300 and the other 1GB platforms _can_ run the latest Junos releases. However, because the feature set (including flow-mode) is heavier, the scaling metrics will be impacted (i.e. CPU load, sessions, routes, etc). However they also confirmed that running in packet mode (which can also be done on all Junos releases) drops the resource load substantially.

Sorry but I can not 100% agree with you. Here are Junos-ES 8.5 release notes
that say that flow-based (ES) Junos is supported on
- J2320 and J2350
- SSG320m and SSG350m (requires conversion kit)
- SSG520m and SSG550m (requires conversion kit)
No J2300/4300/6300 here! Same for higher versions of Junos-ES (and after 9.4 only Junos-ES
exists). I agree that it _will_ run on J2300. However, the question was - what is _supported_
on that platform.
So my point is that if J2300 supports Junos > 9.3 then there must be an official document
that states it. Otherwise no guarantee that any particular features will work exists.

I would agree that it's ambiguous. However, JTAC will take calls on that platform running later versions of Junos. That's one definition of "supported".
Suitability of purpose is another, and that's where getting sage advice from resellers like yourself (or an SE) is always a good idea.

Thanks a lot for clarification, KB_Fan.

OK, I see that I've inadvertently kicked a beehive......
What I'm going to do is run the latest 9.3 version. Our needs are very simple, and it's more important that the versions are within shouting distance of each other than we have the latest gee-whiz features.
That having been said, I need to load the image to a new compact flash. I remember at one point running a program called physdiskwrite to write the files to a CF and have it boot the router. I don't, however, have the docs anymore on this. So - what's the easiest and most foolproof way to write a 9.3 image to a new, freshly-formatted CF? I can reconfigure in a few minutes, so no worries with that.

Check out the note near the bottom of this thread by miliscent.
We just did this with our j4350's.
We spent $20/ea 2GB Sandisk (SDCFH-002G-A11) Ultra II from here:
Then got a cheap usb card reader to read compact flash cards from Walmart for another $15. We put the new 2GB cards in and hooked them to the usb 0 port in the front then made a system snapshot onto them:
request system snapshot media usb partition as-primary
Finally we swapped the internal cards for the new 2GB ones. Easy peasy.
