Changes since Pike 7.6: 
---------------------------------------------------------------------- 
 
o New syntax to index from the end in range operations. 
  A "<" can be added before an index in the [..] operator to count 
  from the end instead. This is convenient to e.g. chop off the last 
  element in an array: a[..<1]. 
 
o Several declarations and definitions (most notably the debug and 
  runtime flags) have moved from main.h to pike_embed.h, in an attempt 
  to add support for embedding. 
 
o New `[..] operator function. 
  Range operations have been separated from the `[] operator function 
  and is handled by a new `[..] which provides greater control in how 
  the range bounds are specified. For compatibility, if there is no 
  `[..] then `[] is still called for range operations. 
 
o Generalized this and this_program. 
  It is now possible to refer to inherits in objects. Example: 
    class A { 
      int a; 
      void foo() { werror("A\n"); } 
    } 
    class B { 
      inherit A; 
      int b; 
      void foo() { werror("B\n"); } 
      A::this_program get_a() { return A::this; } 
    } 
  In the above B()->get_a() will return an object with two symbols, 
  'a' and 'foo', but B()->get_a()->foo() will still write "B\n". 
 
o Unicode escapes. 
  Pike now understands the common way to escape unicode chars, using 
  \uxxxx and \Uxxxxxxxx escapes. These escapes works both in string 
  and character literals and in the preprocessor. The latter means 
  that unicode escapes can be used in identifiers, which is useful if 
  they contain characters that can't be represented raw in the source 
  code charset. 
 
o Stdio.* 
  Stdio.cp can now work recursively in a directory tree. 
  Stdio.cp now keeps permissions when copying. 
  Added Stdio.recursive_mv which works on every OS and also when the 
  destination isn't on the same filesystem as the source. 
 
o Process.popen 
   Process.popen is now able to run in nonblocking mode. If a second 
   argument is provided a file object will be opened with that mode 
   and return, enabling two way communication with the new process. 
 
o bin/precompile.pike 
   Voidable pointer types are no longer promoted to mixed. 
 
o PIKE_PORTABLE_BYTECODE 
   --with-portable-bytecode is now the default. Pike programs that have 
   been dumped on one architecture now can be decoded on another. 
 
o Math.Matrix  
  Multiplication were bugged and gave B*A instead of A*B. Now fixed.  
 
o Destruct reason passed to lfun::destroy. 
  lfun::destroy now receives an integer flag that tells why the object 
  is being destructed, e.g. if it was an explicit call to destroy(), 
  running out of references, or reaped by the garbage collector. 
 
  These integers are defined in the new Object module as 
  DESCTRUCT_EXPLICIT, DESTRUCT_NO_REFS, DESTRUCT_GC and 
  DESTRUCT_CLEANUP. 
 
o Unicode 
  Case information and the Unicode module are updated to Unicode 
  5.0.0. 
 
 
Extensions and New Functions 
 
o Calendar.Badi 
  Support for the Badi calendar used in the Baha'i religion. 
 
New Modules 
 
o ADT.Set 
  ADT.Set implements a datatype for sets. These sets behave much 
  like multisets, except that they are restricted to containing only 
  one instance of each member value. 
 
  From a performance viewpoint, it is probably more efficient for a 
  Pike program to use mappings to serve as sets, rather than using an 
  ADT.Set,so ADT.Set is mainly provided for the sake of completeness 
  and code readability. 
 
o Protocols.DNS_SD 
  This module provides an interface to DNS Service Discovery. The 
  functionality of DNS-SD is described at <http://www.dns-sd.org/>. 
 
  Using the Proctocols.DNS_SD.Service class a Pike program can 
  announce services, for example a web site or a database server, to 
  computers on the local network. 
 
  When registering a service you need to provide the service name. 
  service type, domain and port number. You can also optionally 
  specify a TXT record. The contents of the TXT record varies between 
  different services; for example, a web server can announce a path 
  to a web page, and a printer spooler is able to list printer 
  features such as color support or two-sided printing. 
 
  The service is registered on the network for as long as the instance 
  of the Service class is valid. 
 
o Bittorrent.Tracker 
  Bittorrent tracker with support for scraping and UDP extension. 
 
o Protocols.HTTP.Server.Proxy 
  A simple HTTP proxy. 
 
o Standards.TLD 
  Country domains and other TLDs according to IANA. Useful when 
  parsing log information or providing live information about clients 
  connecting to your server. 
 
o Tools.Shoot 
  Several new tests have been added to benchmark and improve on 
  various aspects of Pike. ReplaceParallel and ReplaceSerial compares 
  the time it takes to replace multiple substrings of a string in a 
  single call to replace and with subsequent calls. 
 
  TagRemoveArraySscanf, TagRemoveDivide, TagRemoveLoop, 
  TagRemoveParserHTML, TagRemovePCRE, TagRemoveSearch and 
  TagRemoveSscanf compares different methods of completing the same 
  task, to remove XML tags from a string. 
 
o Web.CGI 
  Provides a CGI interface on the callee side. Retrieves information 
  from environment variables and populates the variables in the 
  Request object. 
 
New lib: 
Protocols.LDAP module.pmod 
Sql.Sql dsn 
        sqlite 
        sql_array_result 
        sql_object_result 
        tds 
-x test_pike 
 
New src: 
embed/libpike 
tmodule 
code/amd64 
Fuse 
Protocols.DNS_SD 
Charset gb18030 
        gbk 
Parser c.c / pike.c 
GTK2 
SQLite 
 
Incompatible changes 
 
  These incompatible changes can be solved by adding #pike 7.6 to your 
  source file or starting Pike with -V7.6. 
 
o Array.transpose_old 
  This function is removed. 
 
o _Charset 
  This internal module has had most of its content removed. 
 
o Debug.describe_program 
  The API for this debug function has changed. 
 
o Image.Image 
  The functions select_colors(), map_closest(), map_fast() and 
  map_fs() has been removed. Use Image.Colortable operations instead. 
 
o Parser.XML 
  The XML parsers are now stricter in verifying the correctness 
  of the XML. The function compat_allow_errors can be called in the 
  create method of the Parser.XML.Simple and Parser.XML.Validating 
  (with "7.6" as argument for 7.6 compatibility). Parser.XML.Tree can 
  be created with PARSE_COMPAT_ALLOW_ERRORS_7_6 as flag. 
 
o Protocols.LDAP.client 
  The "dn" field wasn't properly utf-8 decoded in 7.6 and earlier. If 
  your application does it yourself, you need to use the compatibility 
  version of this class. 
 
o spider.XML 
  The spider module no longer contains the XML parser. The functions 
  isbasechar(), iscombiningchar(), isdigit(), isextender(), 
  isfirstnamechar(), ishexchar(), isidiographic(), isletter(), 
  isnamechar() and isspace() has also been moved to the Parser module. 
 
o Sql.Sql 
  Pike will no longer create a .column entry in SQL query responses if 
  there is no table name. 
 
o Standards.UUID 
  Functions new() and new_string() has been removed. Use 
  make_version1(-1)->encode() and make_version1(-1)->str() instead. 
 
o Stdio 
  The functions read_file(), read_bytes(), write_file() and 
  append_file() now always throw errors upon errors, to allow easier 
  use as errno doesn't have to be checked. read_file() and 
  read_bytes() still returns 0 if the file does not exists.
