## Changes in API during updates
64+
65+
CEF Python depends on CEF and API breaks are inevitable when updating
66+
to a newer CEF. When updating cefpython to a new version go to the
67+
[GitHub Releases](https://github.com/cztomczak/cefpython/releases) page
68+
and check release notes for all the releases that appeared between
69+
your old version and the new version. Look for lists named
70+
"Changes in API that break backward compatibility".
71+
