The Change
A new FrameRateType fps23976 has been added to AudioPlayHead on develop with commit 86f9c1.
Possible Issues
Previously JUCE would report the FrameRateType fps24 for both 24 and
23.976 fps. If your code uses switch statements (or similar) to handle
all possible JUCE frame rate types, then this change may cause it to fall
through.
Workaround
Add fps23976 to your switch statement and handle it appropriately.
Rationale
JUCE should be able to handle all popular frame rate codes but was
missing support for 23.976.
