- Issue #18919: Added tests for the sunau module. Unified and extended tests
|
||||
for audio modules: aifc, sunau and wave.
|
||||
|
||||
- Issue #18792: Use "127.0.0.1" or "::1" instead of "localhost" as much as
|
||||
possible, since "localhost" goes through a DNS lookup under recent Windows
|
||||
versions.
