-- Issue #8603: Create a bytes version of os.environ for Unix: create
-  os.environb mapping and os.getenvb() function, os.unsetenv() encodes str
-  argument to the file system encoding with the surrogateescape error handler
-  (instead of utf8/strict) and accepts bytes, and posix.environ keys and values
-  are bytes.
+- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
+  mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
+  file system encoding with the surrogateescape error handler (instead of
+  utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.
 
 - Issue #8573: asyncore _strerror() function might throw ValueError.
