Chris Muller has recently done some superb work in Squeak with his Magma
database that provides exactly this within the existing Monticello
framework. In current Squeak 4.5 images if you add the repository
to the Monticello Browser and then add it to the packages one is interested
in (a script to add it to all is trivial), then a "Browse mc history" menu
item becomes available on the class and method lists in the browser and
voila, one can browse the entire class and/or method history.
This feature has been missing for a long time. I really needed it this
morning and wasn't quite aware that it was available already. I expect
this will become a standard feature of new Squeak releases. The server can
easily be duplicated on one's own machine for working detached from the
internet (e.g. via http://localhost:8888/mchistory) and updates itself at

But the work's mostly been done. Chris's work provides class & method.
Package history is there already, with "search history" providing free
text search through a specific package's history, and Chris will be
providing keyword search across all packages soon.
