### Release 4.0 ¶

- Incompatible encrypted and eblob packet format change: AEAD encryption mode with 128 KiB blocks is used now, because previously `nncp-toss` did not verify encrypted packet’s MAC before feeding decrypted data to external command. Older versions are not supported.
- Available free space checking before copying in `nncp-xfer`, `nncp-daemon`, `nncp-call(er)`.
- `nncp-call` has ability only to list packets on remote node, without their transmission.
- `nncp-call` has ability to transfer only specified packets.
- Workability of `xxrate` preference in `calls` configuration file section.
- Dependant libraries are updated.
- Minor bugfixes.
