| * Add the platform function mbedtls_setbuf() to allow buffering to be |
| disabled on stdio files, to stop secrets loaded from said files being |
| potentially left in memory after file operations. Reported by |
| Glenn Strauss. |
| Requirement changes |
| * The library will no longer compile out of the box on a platform without |
| setbuf() if MBEDTLS_FS_IO is enabled. If your platform does not have |
| setbuf(), you can configure an alternative function by enabling |
| MBEDTLS_PLATFORM_SETBUF_ALT or MBEDTLS_PLATFORM_SETBUF_MACRO. |
