Doc Type: Bug Fix
Doc Text:
Prior to this update, eventlet behaved incorrectly around SSL retries. As a consequence, sporadic connection failures (for example, of API calls) occurred. To fix this problem, a patch has been added in which SSL retries use the same data buffer. As a result, SSL retries now work correctly.
