</span>The updates Colin Putney committed to the trunk on Friday, Saturday<br>
27/28th Nov are<br>
<br>
Name: Environments-cwp.60<br>
Author: cwp<br>
Time: 27 November 2015, 5:14:36.376 pm<br>
UUID: c8836cde-f21e-4652-a2e9-73f8de6f00e0<br>
Ancestors: Environments-kfr.59<br>
<br>
Always serialize Bindings as DiskProxies.<br>
<br>
<br>
Name: System-cwp.781<br>
Author: cwp<br>
Time: 27 November 2015, 5:22:38.591 pm<br>
UUID: c0ffbab7-f7ee-4966-ba07-d57436ac42f2<br>
Ancestors: System-mt.780<br>
<br>
Remove specialized serialization of Associations.<br>
Since associations are no longer used as globals, we never need to<br>
serialize them using DiskProxy.<br>
<br>
<br>
Name: System-cwp.782<br>
Author: cwp<br>
Time: 27 November 2015, 9:00:42.904 pm<br>
UUID: ae1f1166-0438-4e78-8ded-46c59c212210<br>
Ancestors: System-cwp.781<br>
<br>
Reload DiskProxies using the current environment<br>
<br>
When looking up objects from the destination image, DiskProxies should<br>
use the current environment, rather than referring to to Smalltalk.<br>
This lets objects on disk be loaded into arbitrary environments.<br>
<br>
These updates are committed to the trunk (i.e. the ongoing development<br>
after the release of 5.0). However in a trunk image<br>
<a href="http://build.squeak.org/job/Trunk/default/lastSuccessfulBuild/artifact/target/TrunkImage.zip" rel="noreferrer" target="_blank">http://build.squeak.org/job/Trunk/default/lastSuccessfulBuild/artifact/target/TrunkImage.zip</a><br>
they do NOT work yet.<br>
<br>
<br>
What you could do as of now<br>
-----------------------------------------<br>
<br>
- File in the updates above into a 4.6 image.<br>
- It should fix the problem (I have not tried yet, so please report if<br>
it is successful).<br>

<br>
</span>The reason is that the new VM crashes, and Colin has reported this to<br>
the Virtual Machine List.<br>
