57. • Feature branching seems like a good

development over
Feature branches

58. How?
• Instead of breaking things, introduce a
new version of the change
• Keep both versions as long as the old is
used
• Remove the old one once it is no longer
used Code
Client
New Code
Other code

59. Add new route
Duplicate existing
code and tests
Change behavior
Remove old code
