Nicolas Cellier uploaded a new version of Monticello to project The Trunk:
http://source.squeak.org/trunk/Monticello-nice.695.mcz

==================== Summary ====================

Name: Monticello-nice.695
Author: nice
Time: 14 February 2019, 1:46:52.89164 pm
UUID: 1933b192-0ab2-bc46-af47-b06f031516b9
Ancestors: Monticello-nice.694

Add a utility for finding last merge of two versions.

A use case:

| mcw allBF540 |
mcw := (MCPackage named: 'Monticello') workingCopy ancestry.
allBF540 := (mcw allAncestors select: [:e | e versionName = 'Monticello-bf.540' ]) asArray.
^mcw lastMergeOf: allBF540 first and: allBF540 last.

Note: implementation is sub-optimal but just works
