+** New function: crypt password salt
+
+Encrypts `password' using the standard unix password encryption
+algorithm.
+
+** New function: chroot path
+
+Change the root directory of the running process to `path'.
+
+** New functions: getlogin, cuserid
+
+Return the login name or the user name of the current effective user
+id, respectively.
+
+** New functions: getpriority which who, setpriority which who prio
+
+Get or set the priority of the running process.
+
+** New function: getpass prompt
+
+Read a password from the terminal, first displaying `prompt' and
+disabling echoing.
+
+** New function: flock file operation
+
+Set/remove an advisory shared or exclusive lock on `file'.
+
+** New functions: sethostname name, gethostname
+
+Set or get the hostname of the machine the current process is running
+on.
+
+** New function: mkstemp! tmpl
+
+mkstemp creates a new unique file in the file system and returns a
+new buffered port open for reading and writing to the file. TMPL
+is a string specifying where the file should be created: it must
+end with `XXXXXX' and will be changed in place to return the name
+of the temporary file.
+
+** New function: open-input-string string
+
+Return an input string port which delivers the characters from
+`string'. This procedure, together with `open-output-string' and
+`get-output-string' implements SRFI-6.
+
+** New function: open-output-string
+
+Return an output string port which collects all data written to it.
+The data can then be retrieved by `get-output-string'.
+
+** New function: get-output-string
+
+Return the contents of an output string port.
+
+** New function: identity
+
+Return the argument.
+
+** socket, connect, accept etc., now have support for IPv6. IPv6 addresses
+ are represented in Scheme as integers with normal host byte ordering.
+
+** New function: inet-pton family address
+
+ Convert a printable string network address into an integer. Note
+ that unlike the C version of this function, the result is an
+ integer with normal host byte ordering. FAMILY can be `AF_INET'
+ or `AF_INET6'. e.g.,
+ (inet-pton AF_INET "127.0.0.1") => 2130706433
+ (inet-pton AF_INET6 "::1") => 1
+
+** New function: inet-ntop family address
+
+ Convert an integer network address into a printable string. Note
+ that unlike the C version of this function, the input is an
+ integer with normal host byte ordering. FAMILY can be `AF_INET'
+ or `AF_INET6'. e.g.,
+ (inet-ntop AF_INET 2130706433) => "127.0.0.1"
+ (inet-ntop AF_INET6 (- (expt 2 128) 1)) =>
+ ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff
+
+** Deprecated: id
+
+Use `identity' instead.
+
+** Deprecated: -1+
+
+Use `1-' instead.
+
+** Deprecated: return-it
+
+Use `noop' instead.
+
+** Deprecated: string-character-length
+
+Use `string-length' instead.
+
+** Deprecated: flags
+
+Use `logior' instead.
+
+** Deprecated: close-all-ports-except.
+
+This was intended for closing ports in a child process after a fork,
+but it has the undesirable side effect of flushing buffers.
+port-for-each is more flexible.
