3.5 OTP 24

Old Crypto API

The Old API will be removed as of OTP 24. The support was formally deprecated as of OTP 23.

For replacement functions see the New API.

Distributed Disk Logs

The distributed disk_log feature is as of OTP 23 deprecated and will be removed in OTP 24.

Megaco version 3 encoding config

As of OTP 24, the pre-release version 3 encoding configs; prev3a, prev3b and prev3c will be removed. Use the full version instead.

The (encoding) config option for the full version, {version3, 3}, will still be supported, even though its no longer necessary to specify it this way.
