  [Bug Fix with Incompatible Changes]
    * There are some imcompatible changes in is_type operator to fix the following bug.
      
      https://github.com/yuki-kimoto/SPVM/issues/545
      
      For this, is_type operator must check runtime type instead of compile-time type if TYPE is an object type including object[].
      
      And if TYPE is any object type(object), an compilation error occurs.
  [Incompatible Changes]
    * warn operator output a stack trace even if the end of the input string is "\n".
      Along with this, the same change occurs in warn Native API.
      
      The reason of this change is that debugging data with trailing \n does not show a stack trace.
      
      We will add Fn#print_stderr and Fn#say_stderr to achieve the original behavior, no stack trace, of warn operator.

    * The --module-dir option in the spvmcc command is renamed to the --class-path.
    * The regex that remove extention from config file is changed to (\.[^\.]+)?\.config$.
    * The args field in the SPVM::Builder::Resource is renamed to the argv field.
0.9703 2023-04-07
  [New Features]
    * Added the following methods in the Fn class.
    
      static method merge_options : object[] ($options1 : object[], $options2 : object[]);
      static method object_to_int : int ($object : object);
      static method object_to_long : long ($object : object);
      
    * Added the following methods in the Sort class.
    
      static method sort_options_asc : void ($options : object[]);
      
  [Changes]
    * Hash randomization doesn't use system time as the seed. Use the address of the Hash object.
  [Incompatible Changes]
    * Removed SPVM::Time. Use SPVM::Sys::Time instead.
    * Removed SPVM::Time::Info. Use SPVM::Sys::Time::Tm instead.
0.9702 2023-04-07
  [Changes]
    * Improved the exception message when native source files are compiled.
      [After]
        "The $source_file file can't be compiled by the following command:\n@$cc_cmd\n"
    * Even if the compilation of a native source file failed, the command is output to STDERR.
  [Changes]
    * SPVM and standard modules are compiled by C99, not GNU C99.
    * The config file that is generated by the spvmcc command use new_c99 instead of new_gnu99.
  [Deprecateion]
    * (Deprecated) The methods of SPVM::Time will be implemented in SPVM::Sys::Time
      (Deprecated) SPVM::Time::Info will be implemented in SPVM::Sys::Time
      This is due to the decision not to include the ability to invoke system calls in the core of the SPVM.
      
0.9701 2023-04-03
  [Version Number Fix]
    * This release is 0.9701.
  [Incompatible Changes]
    * Renamed the global_before_compile field in the SPVM::Builder::Config::Exe to before_each_compile
  [New Features and Deprecation]
    Add the add_ccflag in the SPVM::Builder::Config class. the add_ccflags method is deprecated.
    Add the add_include_dir in the SPVM::Builder::Config class. the add_include_dirs method is deprecated.
    Add the add_ldflag in the SPVM::Builder::Config class. the add_ldflags method is deprecated.
    Add the add_lib_dir in the SPVM::Builder::Config class. the add_lib_dirs method is deprecated.
    Add the add_lib in the SPVM::Builder::Config class. the add_libs method is deprecated.
    Add the add_static_lib in the SPVM::Builder::Config class. the add_static_libs method is deprecated.
    Add the add_source_file in the SPVM::Builder::Config class. the add_source_files method is deprecated.
  [Bug Fix]
    * Fixed the bug that Makefile.PL that is generated by the spvmdist command doesn't output MIT license meta information.
  [Incompatible Changes]
    * Removed the deprecated new_pointer_raw, new_pointer, new_pointer_by_name Native API are removed.
    * Removed the unused object_type_category_offset Native API is removed.
    * Changed the ID of Native APIs. This breaks binary compatibility. This maybe the last ID changes(0 - 204) of Native APIs.

        # Do something such as environment check.
      }
    * SPVM is added to CONFIGURE_REQUIRES and PREREQ_PM of the Makefile.PL that is generated by the spvmdist command.
      SPVM is needed for both generating Makefile.PL and the runtime.
      I think only CONFIGURE_REQUIRES is good, but I found the cpanm command didn't see CONFIGURE_REQUIRES in a case,
      so both specifications is safe.
    * .gitignore that is generated by the spvmdist command is changed.

      =head1 Standard IO

      C<stdin>, C<stdout>, C<stderr> in C<C language> is set to the binary mode on all systems.

      This means the escape character of the string literal C<"\n"> is not coverted to C<"\r\n"> when it is got from C<stdin> and it is printed to C<stdout> and C<stderr>.

      C<stdin>, C<stdout>, C<stderr> can be changed to the text mode using the L<native module|SPVM::Document::NativeModule>, but don't do that.

        [NON BACKWORD COMPATIBLE CHANGES]
        * Remove implicte type convertion Perl array reference to SPVM object and element[]
          This is a bug fix because the right convesion is impossible,
          but the following code raise an exception, and the code must be rewirtten.
          [Before]
          my $list = SPVM::List->new([]);
          [After]
          my $list = SPVM::List->new(SPVM::new_object_array("Int[]", []));
        * The type of argument of Hash->new is changed. Sorry, this is merely my bad mistake. The type of value of hash is any object type.
          [Before]
          static method new : Hash ($key_values : element[]);
          
          [After]
          static method new : Hash ($key_values : object[]);
        * Remove oarray type that is deprecated at 0.9509.
        * The feature of element[] type is merged to object[] type and remove element[] type.

0.9509  2021-03-23
        [DEPRECATIONS]
        * oarray type is deprecated. oarray type will be removed at 0.9510.
        [WARNINGS]
        * Interfaces and IDs of Native APIs that is added after 0.9506+(181+) will be changed many times.
          because I realize Native APIs that compile SPVM are not yet implemented correctly in tests.
        [BUG FIX]
        * Fix the bug that spvmcc can't detect the change of config file.
        [CHANGE]
        * Add element[] type. This is same as oarray type, but element[] type has correct type dimension.
        * Add Fn->is_numeric_array, Fn->is_mulnum_array doc.
        * Add Fn->is_object_array
        * Add is_object_array native API.
        * Native API get_elem_byte_size uses only runtime information
        * Native API has_callback uses only runtime information
        * Native API has_interface uses only runtime information
        * Separate compiler allocator and runtime allocator.
          The memory allocated at compile time is freed just before runtime.
        * Add get_method_id_without_signature native API.
        * Add get_constant_string_value native API.
        * Add compiler_build_runtime_info native API.
        * Rename compiler_build_runtime_info to compiler_build_runtime native API.
        * Change Native API "compiler_build_runtime" argument and return values.
        [NON BACKWORD COMPATIBLE CHANGES]
        * oarray type signature change from oarray to element[].
          For this reason, 0.9510 don't have binary compatibility of precompiled source from 0.9509
        * Rename Internal native API "compiler" field to "runtime_info"
          because in this release SPVM compiler and runtime is completly separated.
          I think the effect is litte because this is internal field.
        * Rename native API new_compiler to compiler_new
          becuae this is my mistake and compiler API shoud start compiler_.
          This has a litte effect over 0.9506+.
        * The native API compiler methods is changed to runtime methods
          because I realize setting and getting native/precompile address
          should be done at only runtime. This has a litte effect over 0.9506+.
          
          Change Native API compiler_get_native_method_address to get_native_method_address
          Change Native API compiler_set_native_method_address to set_native_method_address
          Change Native API compiler_get_precompile_method_address to get_precompile_method_address
          Change Native API compiler_set_precompile_method_address to set_precompile_method_address
       * Internally used "memory_blocks_count" native API is no more used. The count of memory blocks is managed in "runtime_info".
         Because this is internal used, the effect is little.
        * Change the following Native APIs. First argument don't receive env.

  - Support precompile subroutine in distribution
    In this version, spvm subroutine can be precompiled before runtime.
    
    You can create precompiled shared library by the following command.
    
      perl -MSPVM::Build -e "SPVM::Build->new(build_dir => 'spvm_build')->create_shared_lib_precompile_dist('Point')";

  - remove len keyword and add scalar keyword
    SPVM don't have scalar context and list context, but Perl have them.
    In SPVM, you can get array by
    
      @$values
    
    syntax. but this confuse you sometime
    because
    
      foo(@$values);
    
    is seem list expansion. This is always array length in SPVM.
    Until now I provided len keyword , but this is not Perlish syntax.
    From now I provide scalar keyword and another array syntax.
      
      scalar @$values
    
    You can write the following subroutine call
    
      foo(scalar @$values);
  - add SPVM_NATIVE_SUB macro to spvm_native, and SPVM native function defenition way is changed to the following
      
      // My::Example::sin
      int32_t SPVM_NATIVE_SUB(My__Example__sin) (SPVM_ENV* env, SPVM_VALUE* args) {
        (void)env;
        
        double value = sin(args[0].dval);
        
        args[0].dval = value;
        
        return 0;
      }
    
    SPVM_NATIVE_SUB macro automatically expand function name to SPVM_NATIVE_My__Example__sin.
