Rearranged a bit.

Rev: CHANGES:1.110

1:   Changes since Pike 7.6:   ----------------------------------------------------------------------    - o Added ABI selection. + This is a high level list of changes between Pike 7.6 and Pike 7.8. + General bug fixes, build fixes and optimizations are not mentioned + here. For a complete list of changes, please consult the CVS changelog + either directly or through Code Librarian.    -  It's now possible to select whether to compile in 32bit or 64bit -  mode at configure time by using the --with-abi option. +     -  + New / improved language functionality + ------------------------------------- +    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 Improved support for embedding. -  -  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 Major compiler API cleanups. -  -  The Pike compiler is now executing in a pike function context -  (rather than in an efun context), and it is possible to customize -  some of its behaviour via inherit (rather than via handler objects). -  As a consequence the compiler is now much closer to being thread-safe. -  +    o New `[..] operator function.       Range operations have been separated from the `[] operator function
90:      o New (stricter) type checker for function calls.    -  The type checker for function calls is now based on the concept -  of currification. This should provide for error messages that -  are more easily understood. It also is much better att typechecking -  function calls utilizing the splice (@) operator. -  The mechanisms used by the typechecker are also made available as -  Pike.get_first_arg_type(), Pike.low_check_call() and Pike.get_return_type(). +  The type checker for function calls is now based on the concept of +  currification.

The mechanisms used by the +  typechecker are also made available as Pike.get_first_arg_type(), +  Pike.low_check_call() and Pike.get_return_type().      o Added generic attributes for types.   
108:       string(0..255) bytes;    - o Stdio -  -  - Stdio.cp can now work recursively in a directory tree. It will -  also keep the permissions of files it copies. -  -  - Added Stdio.recursive_mv which works on every OS and also when the -  destination isn't on the same filesystem as the source. -  -  - Added more symbolc default termcap/terminfo bindings to -  Stdio.Readline. -  -  - Improved support for Terminfo on NetBSD. -  -  - read_file(), read_bytes(), write_file() and append_file() will may -  now throw exceptions on uncommon errors such as when write_file is -  unable to write all its data. -  -  - Stdio.File->openat() opens a file relative to an open directory. -  +    o Support for having multiple different active backend implementations.    FIXME: example? -  ... -  The global variable next_timeout is no more. It has been replaced by -  a backend-specific variable. Added backend_lower_timeout() for accessing -  the new variable. This fixes issues GTK, GTK2 and sendfile had with the -  new backend implementation. +     -  NOTE! -  NOTE! C-API incompatibility! -  NOTE! -  NOTE! Changed the argument for backend callbacks! -  NOTE! -  NOTE! The argument is now a struct Backend_struct * when called -  NOTE! at entry (was NULL). -  NOTE! The argument is now NULL when called at exit (was 1). -  NOTE! -  - o bin/precompile.pike -  -  Voidable pointer types are no longer promoted to mixed. -  +    o cpp       The preprocessor now supports macro expansion in the #include and #string    directives.    - 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 Destruct reason passed to lfun::destroy.       lfun::destroy now receives an integer flag that tells why the object
169:    DESCTRUCT_EXPLICIT, DESTRUCT_NO_REFS, DESTRUCT_GC and    DESTRUCT_CLEANUP.    - o Support for class symbols with storage in parent scope. -  Also added support for aliased symbols. -  +    o Improved support for mixin.       The Pike compiler now supports mixin for symbols that have been
196:    Case information and the Unicode module are updated to Unicode    5.1.0.    - o protected + o The keyword protected       The modifier protected is now an alias for the modifier static.    NOTE: In next release static will be deprecated.    - o Pike_fp->context -  -  Pike_fp->context is now a pointer to the current struct inherit -  rather than a copy of it. This allows for easier access to -  inherited symbols in C-code. -  -  NOTE! -  NOTE! C-API incompatibility! -  NOTE! -  - o Inherit level argument added to several object handling functions. -  -  In order to implement subtyping of objects, an extra argument -  "inherit_level" has been added to many object indexing related -  functions. -  -  NOTE! -  NOTE! C-API incompatibility! -  NOTE! -  - Extensions and New Functions -  +    o __attribute__ and __deprecated__       It's now possible to set custom attributes on types. This is
258:       #pragma deprecation_warnings    +  + Extensions and New Functions + ---------------------------- +    o limit()       The new toplevel function limit(a, x, b) is a convenience function
739:       FIXME    + o Stdio +  +  - Stdio.cp can now work recursively in a directory tree.

812:    real time clocks in use.       - New Modules + New modules / classes / methods added + -------------------------------------      o Fuse

937:         Deprecations + ------------      o The keyword nomask has been deprecated. It was functionally    equivivalent with the keyword final.      o Stdio.File->set_peek_file_before_read_callback() is deprecated.    -  +    Incompatible changes -  + --------------------       These incompatible changes can be solved by adding #pike 7.6 to your    source file or starting Pike with -V7.6.
1013:   o The modules Mird, Perl and Ssleay have been removed.       + C level module API + ------------------ +  + o Improved support for embedding. +  +  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 Major compiler API cleanups. +  +  The Pike compiler is now executing in a pike function context +  (rather than in an efun context), and it is possible to customize +  some of its behaviour via inherit (rather than via handler objects). +  As a consequence the compiler is now much closer to being thread-safe. +  + o The global variable next_timeout is no more.
