+@itemize
+@item (X)Salsa20 is replaced with ChaCha20. Theoretically it should be
+faster and more secure. Previous versions are not compatible with it!
+@item Ability to use TUN-interfaces under GNU/Linux. FreeBSD has already
+supported them without any modifications.

+@node Release 6.0
+@section Release 6.0
+@itemize
+@item Argon2d is replaced with Balloon hashing. Found Argon2 libraries
+written on pure Go have various problems. Moreover Argon2i should be
+used instead, but it has some possible
+@url{http://eprint.iacr.org/2016/027, cryptographic defects}. So it is
+replaced with much more simpler (and seems even cryptographically
+better) @url{https://crypto.stanford.edu/balloon/, Balloon hashing}.

+@item Optional ability to use syslog for logging, with
+@url{https://tools.ietf.org/html/rfc5424, RFC 5424}-like
+structured records.
+@item XTEA algorithm is not used anymore for nonce obfuscation, but
+BLAKE2b-MAC instead. Encryptionless mode now really does not depend on
+encryption functions.

+@itemize
+@item TAP interface name and remote peer's address are passed to up- and
+down- scripts through environment variables.
+@item Update Argon2 library to use version 1.3 of the algorithm.

+@node Release 5.6

+@node Release 5.4
+@section Release 5.4
+@itemize
+@item Added optional @ref{Timesync, time synchronization} requirement.
+It will add timestamps in handshake PRP authentication, disallowing to
+repeat captured packet and get reply from the server, making it visible
+to DPI.

+@node Release 5.3
+@section Release 5.3
+@itemize
+@item Fixed minor bug with @command{newclient.sh} that caught

+Just replaced stdout output to stderr for that prompt.

+@itemize
+@item Ability to read passphrases directly from the terminal (user's
+input) without using of keyfiles. @command{storekey.sh} utility removed.
+@end itemize

+@node Release 5.1
+@section Release 5.1
+@itemize
+@item Server is configured using @url{http://yaml.org/, YAML} file. It
+is very convenient to have comments and templates, comparing to JSON.
+@item Incompatible with previous versions replacement of @emph{HSalsa20}
+with @emph{BLAKE2b} in handshake code.

+
+@node Release 5.0
+@section Release 5.0
+@itemize
+@item New optional @ref{Encless, encryptionless mode} of operation.
+Technically no encryption functions are applied for outgoing packets, so
+you can not be forced to reveal your encryption keys or sued for
+encryption usage.
+@item @ref{MTU}s are configured on per-user basis.
+@item Simplified payload padding scheme, saving one byte of data.
+@item Ability to specify TAP interface name explicitly without any
+up-scripts for convenience.
+@item @command{govpn-verifier} utility also can use @ref{EGD}.
