CHANGES: Added a few recent changes.

Also adjusted the formatting to be more consistent through out.

113:    not work before.      o "Safe" index +     Copied from a popular extension to other C-like languages.       X[?ind] is equivalent to ((auto _ = X),(_ && _[ind]))
136:    This is especially useful then A is not actually 0, but an object    that evaluates to false, or UNDEFINED.    +    New preprocessor features   -------------------------      o Support for the ", ##__VA_ARGS__" cpp feature. -  +     This makes the ‘##’ token paste operator have a special meaning    when placed between a comma and a variable argument. If you write   
151:    token preceding ‘##’ is anything other than a comma.      o The preprocessor can now be run with a cpp prefix feature. +     This is currently used by the precompiler to avoid two levels of    preprocessing, one using "#cmod_" as the prefix and the other "#".      o Dynamic macros -  +     You can now add programatic macros. There is currently no syntax    that can be used to define these while compiling code, but you can    add them from one program before compiling plug-ins/modules.
210:   -------------      o New significantly faster block allocator +     The free in the old one was O(n^2), which means that as an example    creating a lot of objects and then free:ing them mainly used CPU in    the block allocator.
262:    faster.      o Several other optimizations to execution speed has been done +     + object indexing (cache, generic speedups) -  +     + lower_apply, changes to apply in general    Taken together these individually small optimizations speeds up at    least pike -x benchmark more than 5%. -  +     + A lot of opcodes implemented in machine-code for x86-64    This speed up the loop benchmarks close to a factor of 3. But then    again, most real code is nothing like that benchmark. -  +     + Several new opcodes added    As an example an observation was that most branch_if_zero is    followed by an is_eq, is_lt or is_gt or similar. Those opcodes
278:    pop_stack etc.      o Faster hash-function for strings +     + Also siphash24 was added and is used in case the string hash table    becomes inefficient    -  +    Deprecated features and modules   -------------------------------      o Tools.PEM and Tools.X409 deprecated -  +     Use the corresponding modules in Standards.      o The built in sandbox is now deprecated -  +     Unless somebody wants to take ownership of the feature and keep it    up to date the security system will be removed in the next stable    release.    -  +    Removed features and modules   ----------------------------      o Removed facets -  +     The optional (and not enabled by default) support for facet classes    has been removed, since it was only partially done and not really    used.      o It is no longer possible to compile pike without libgmp. -  +     Bignums are now a required language feature      o The old low-level 'files' module has been renamed to _Stdio
308:   o 'GTK' is now GTK2, not GTK1 unless the system has no GTK2 support.      o Locale.Charset +     The charset module is now available on the top level as 'Charset'    -  + o The compiler now warns about switch statements where the cases +  aren't enumerable, since these will generate random failures +  if the code is read from a dump. +  +    New modules   -----------      o Pike.Watchdog -  +     A Watchdog that ensures that the process is not hung for an extended    period of time. The definition of 'hung' is: Has not used the    default backend.
330:    was called.      o Crypto.Password +     A module that can be used to verify and create passwd/ldap style    password hashes.       It tries to support most common password hashing schemes.      o Debug.Profiling -  +     Tools useful for collecting and format for output the profiling    information generated when pike is compiled --with-profiling.      o NetUtils -  +     This module contains a lot of functions useful for the storage and    processing of network addresses, it supports IPv4 and IPv6.      o Added ADT.CritBit module -  +     Mapping-like key-sorted data structures for string, int and    float-keys (ADT.CritBit.Tree, ADT.CritBit.IntTree,    ADT.CritBit.FloatTree). Implemented in C.      o Standards.BSON -  +     A new module for working with BSON serialized data.    See      o Geography.GeoIP -  +     Does geolocation of IPv4-numbers using databases from    or      o Protocols.WebSocket -  +     An implementation of the WebSocket (RFC 6455) standard, both server    and client      o Image.WebP -  +     Encoder and decoder for the WEBP image format.    More information about the format can be found on      o Serializer -  +     APIs useful to simplify serialization and deserialization of    objects Mainly it allows you to easily iterate over the object    variables, including the private ones.
375:    using encode_value.      o Filesystem.Monitor and the low level System.Inotify + System.FSEvents +     Basic filesystem monitoring.       This module is intended to be used for incremental scanning of a
385:    polling approach.      o Mysql.SqlTable +     This class provides some abstractions on top of an SQL table.       At the core it is generic for any SQL database, but the current
397:    between SQL and pike data types      o Parser.CSV +     This is a parser for line oriented data that is either comma,    semi-colon or tab separated. It extends the functionality    of the Parser.Tabular with some specific functionality related    to a header and record oriented parsing of huge datasets.      o ZXID -  +     ZXID is a library that implements SAML 2.0, Liberty ID-WSF 2.0    and XACML 2.0.   
410:    to the C one, but using generally accepted Pike syntax.      o Git +     A module for interacting with the Git distributed version control    system.      o Val -  +     This module contains special values used by various modules, e.g.    a Val.null value used both by Sql and Standards.JSON.   
425:    base classes defined here provide required functionality directly.      o __builtin +     The __builtin module is now a directory module, so that it can provide    a suitable namespace for code written in Pike intended for being    inherited from modules written in C (cf precompile).       -  +    Extensions and new functions   ----------------------------   o Bz2.File added -  +     It implements a Stdio.File like API, including support for the same    iterator API that Stdio.File has, allowing for convenient line    iterations over BZ2 compressed files. -  +     | foreach( Bz2.File("log.bz2")->line_iterator(); int n; string line )      o Image.JPEG -  +     + decode now supports basic CMYK/YCCK support -  +     + exif_decode is a new function that will rotate the image    according to exif information      o String.Buffer -  +     String.Buffer can now add the storage from a different String.Buffer    object with the add() method.   
456:    position.      o SDL.Music added to SDL. +     Allows the playback of audio/music files.    Requires the SDL_mixed library.      o System.TM -  +     Low-level wrapper for struct tm.       This can be used to do (very) simple calendar operations. It is,
468:    and localtime() and friends, but in a (perhaps) easier to use API.      o decode_value now throws the error object Error.DecodeError. +     Useful to catch format errors in the decode string.      o Process.daemon -  +     The daemon() function is for programs wishing to detach themselves    from the controlling terminal and run in the background as system    daemons.      o Debug.pp_object_usage() -  +     Pretty-print debug information, useful to get debug information    about object counts and memory usage in pike applications.   
483:    for RAM-usage in C-objects that allocate their own memory.      o Mysql +     + Added support more modern client libraries (incl. MariaDB) -  +     + Mysql.mysql now has methods to query the id or SQLSTATE of the    last error.      o Protocols.DNS -  +     + Prevent endless loops in maliciously crafted domain names. -  +     + Add QTYPE T_ANY to DNS enum EntryType in DNS.pmod. -  +     + Handle truncated labels -  +     + TCP client and server support      o Thread no longer inherits Thread.Thread (aka thread_create)
498:   o Thread.Farm now might work      o Cmod precompiler. +     + inherit "identifier"    -- inherit the program returned by calling master()->resolve() on    the specified identifier. Useful to inherit code written in pike.      o String.levenshtein_distance() -  +     The function calculates the Levenshtein distance between two    strings. The Levenshtein distance describes the minimum number of    edit operations (insert, delete or substitute a character) to get
513:    differences is expected.      o System.sync() +     Synchronizes the filesystem on systems where this is possible    (currently windows and UNIX-like systems).      o System.getloadavg() -  +     Return the current 1, 5 and 15 minute system load averages as an array.      o glob() -  +     The glob function has been extended to accept an array of globs as    the first (glob pattern) argument.   
528:    entries that match any glob in the first array.      o Stdio.UDP(): +     + added IPv6 multicast support -  +     + added set_buffer      o Stdio.File(): -  +     + send_fd and receive_fd    These functions can be used to send and receive an open    file-descriptor over another file-descriptor. The functions are
545:       _fd is still available for compatibility, but internally it is gone.    +  + Fixed grantpt() on Solaris failing with EPERM. +    o Unicode databases updated to 6.3.0 from 5.1.0 -  +     This is the latest released Unicode database from      o The Search search engine module has seen several fixes -  +     + Added support for padded blobs. This improves performance when    incrementally growing blobs. This feature is only enabled if    Search.Process.Compactor says this is OK, see the documentation
