New submission from Roger Taylor <[email protected]>:
An IntFlag member before 3.8.6 was converted to an integer in an f-string.
After 3.8.6, the textual IntFlag class and member name are placed in the
interpolated f-string instead of the integer.
3.8.3: f"... {X.F} ..." where X.F = 1 << 4 will give "... 16 ..."
3.8.5: Same
3.8.6: f"... {X.F} ..." where X.F = 1 << 4 will give "... X.F ..."
I have reproduced this on Linux using the version compiled and installed by
pyenv, and on Windows using the 32-bit versions from the downloadable
standalone installer.
Now I have to locate and go through all my SQL statements and verify that they
explicitly convert IntFlag values to integer to avoid the errors introduced by
this regression.
