+@item @strong{Incompatible} configuration file format change: YAML is
+ replaced with Hjson, due to its simplicity, without noticeable lack
+ of either functionality or convenience.
+@strong{Incompatible} plain packet format changes. Older versions are
+ not supported. @code{zlib} compression is replaced with
+ @code{Zstandard}, due to its speed and efficiency, however library
+ version is not mature enough.
+@item @command{nncp-cfgnew} generates configuration file with many
+ comments. @option{-nocomments} option can be used for an old
+ behaviour.
+@item Duplicate filenames have @file{.CTR} suffix, instead of
+ @file{CTR}, to avoid possible collisions with @file{.nncp.chunkCTR}.
+@item Files and directories are created with 666/777 permissions by
+ default, allowing control with @command{umask}.
+@item Updated dependencies.
+@item Full usage of go modules for dependencies management
+ (@code{go.cypherpunks.ru/nncp/v5} namespace is used).
