Thanks... Because each time I get a new develop version.
Try it next version.

If you already have a nice compiled version of latest develop, you can
merge in your old branch *into* develop. With latest develop checked
out, run the following:

1. git checkout -b "old_is_new"
2. git fetch 
3. git merge trac/
4. make

Step 2 is only if you don't already have the latest version of that ticket.

Compared to the newly compiled develop, this will touch only the files
that were modified in your ticket. That saves a lot of compilation time
when you're working on branches that have fallen far behind. That goes
whether or not latest develop broke backwards compatibility.

If moving from a new branch to an old branch, you can either
- merge in latest develop, or
- make distclean && make



Second option isn't very sustainable if you have to do it a lot, though.

I looked through several of the threads in sage-release but couldn't 
(quickly) find anything more detailed than this.  What happened that Sage 7 
is not upgradeable?

I think that it would then make sense to have some message print out if 
someone tries sage -upgrade (if that's even still supported) lest they hose 
their Sage install, that's been a problem with such updates in the past as 
well. 

Also, can you give a little more guidance on how to still use "old" git 
branches - can we just merge in the newest Sage or will that cause problems 
as well?

Thanks,
- kcrisman
