Changes since 13675:
- Fix cloning MessageSet's. - Pointer-chaser, display the id-hash of Morph's in the path to chased object. - Sending basicNew to CompiledMethod may crash the VM, so don't do that. - Fix incorrect display of underscore and caret in case of WideString displayed in DejaVu sans Strike fonts.
Bad news I'm afraid. Found a serious bug in the final release candidate.
To reproduce, start up Squeak4.5-13680.image, download the current version of Collections to the package-cache (Collections-ul.564.mcz), and load it from the package-cache. There's an infinite recursion apparently due to WriteStream>>nextPutAll: being not understood (!!). For some reason the load decides to remove nextPutAll:. Here's part of the stack:

I don't have much time to investigate over the weekend but someone else with more Monticello smarts may figure this out..
BTW, it may be related to hashing. When I try the same thing in a Spur-ised Squeak4.5-13680.image (where I'm loading a patched version of Collections-ul.564.mcz to restore source to the changed methods in Character that have no source after the bootstrap) it locks up at a similar point but die to a deadlock in preference access. So I suspect that there's some instability in Monticello loading that's affected by the different identityHashes obtained in Spur and SqueakV3.
I had hoped to use the release candidate on Spur before using it on SqueakV3 but hit this bug. Hubris :-( ... ;-)

Could you clarify exactly what you mean by "download the current version of Collections to the package-cache (Collections-ul.564.mcz)"?
I already had (Collections-ul.564.mcz) in my package-cache so I simply loaded it (even though its already loaded into 4.5-13680, so why am I/you doing it in the 1st place?).
Nothing happened. No lockup. Same package version. No difference.

Yes. The issue was that the package on squeak45 was empty. Chris uploaded a valid file as I didn't have one locally. So panic over :p

Hi,
two little notes:
There is an open mantis bug http://bugs.squeak.org/view.php?id=7796 about the wrong links at www.squeak.org/Download I hope this can be solved for the upcoming 4.5 release
Do we need the "Universe Browser (Basic)" and "Package Universe Browser" in the Apps menu? The browser list is empty and "update list from network" shows "could not resolve server" error.

Yes, there is rekindled interest in revamping the entire site. (cc: Chris C.)

Universes is still part of 4.5. In 4.6 and beyond, I'm sure thoughtful discussions about Universes and more will happen that will result some things being excluded in future image versions, but still loadable as external packages.

Universes is still part of 4.5.
In what way? Is there any universe for 4.5 that works? I dont think there is even one that works for 4.1…

In the way that Nicolai asked: It's presence under the Apps menu. No one took it out during 4.5.

Right. It may or may not be a good idea to have Universes in the image, but that is a discussion for the next release cycle. Squeak 4.5 is complete.

Yea, I anticipate Ken and I pushing it over the top this week. We need to play with nginx and tinydns and that's it. (Unless there's something Ken knows about that I don't).
