  <p>This document describes the changes made to the Reltool system
    from version to version. The intention of this document is to
    list all incompatibilities as well as all enhancements and
    bugfixes for every release of Reltool. Each release of Reltool
    thus constitutes one section in this document. The title of each
    section is the version number of Reltool.</p>

	    A new element, <c>Opts</c>, can now be included in a
	    <c>rel</c> tuple in the reltool release specific
	    configuration format: {rel, Name, Vsn, RelApps, Opts}.</p>
          <p>
	    This supports the use of <c>{rel, Name, Vsn, RelApps,
	    [{load_dot_erlang, false}]}</c> to prevent the boot
	    script from running the <c>.erlang</c> file.</p>
          <p>
	    The incompatibilities are as follows:</p>
          <p>
	    * The return from <c>reltool:get_config/1</c> and
	    <c>reltool:get_config/3</c> includes the new <c>rel</c>
	    tuple for all releases where the <c>load_dot_erlang</c>
	    option is set to <c>false</c>.<br/> * The return from
	    <c>reltool:get_config/3</c> includes the new <c>rel</c>
	    tuple for ALL releases if the <c>InclDefs</c> parameter
	    is set to <c>true</c>.</p>

	    Dependencies specified in .app files would earlier only
	    be followed for applications that are included in a 'rel'
	    spec in the reltool config. For other applications, only
	    xref would decide the dependencies.</p>
          <p>
	    Some dependency chains would even be missed for
	    applications that are included in a 'rel' spec in the
	    reltool config. E.g.</p>

	    <list> <item>Application x has y as included application,
	    and y in turn has z as included application. Then z is
	    not included. </item> <item>Application x has y in its
	    'applications' tag in the .app file, and y in turn has z
	    as included application. Then z is not included.</item>

	    When adding a regexp to a filter in reltool using

	    Reltool used to fail if an application was mentioned in
	    the config file which was not found in the file system,
	    even if the application was explicitly excluded in the
	    config. This has been changed and will only produce a
	    warning. If the application is not explicitly excluded it
	    will still cause reltool to fail. Thanks to Håkan

	    <list> <item> If <c>incl_cond</c> was set to
	    <c>derived</c> on module level, then reltool_server would
	    crash with a <c>case_clause</c>. This has been corrected.
	    <c>incl_cond</c> on module level now overwrites
	    <c>mod_cond</c> on app or sys level as described in the
	    documentation. </item> <item> If a <c>rel</c> spec in the
	    reltool config does not contain all applications that are
	    listed as <c>{applications,Applications}</c> in a
	    <c>.app</c> file, then these applications are
	    autmatically added when creating the <c>.rel</c> file.
	    For 'included_applications', the behaviour was not the
	    same. I.e. if a <c>rel</c> spec in the reltool config did
	    not contain all applications that are listed as
	    <c>{included_applications,InclApplications}</c> in a
	    <c>.app</c> file, then reltool would fail with reason
	    "Undefined applications" when creating the <c>.rel</c>
	    file. This has been corrected, so both
	    <c>applications</c> and <c>included_applications</c> are
	    now automatically added if not already in the <c>rel</c>
	    spec. </item> <item> The <c>rel</c> specification now
	    dictates the order in which included and used
	    applications (specified in the <c>.app</c> file as
	    <c>included_applications</c> and <c>applications</c>
	    respectively) are loaded/started by the boot file. If the
	    applications are not specified in the <c>rel</c> spec,
	    then the order from the <c>.app</c> file is used. This
	    was a bug earlier reported on systools, and is now also
	    implemented in reltool. </item> <item> Instead of only
	    looking at the directory name, reltool now first looks
	    for a <c>.app</c> file in order to figure out the name of
	    an application. </item> </list>

	    Miscellaneous corrections: <list> <item> Start of reltool
	    GUI would sometimes crash with a badmatch in
	    reltool_sys_win:do_init. This has been corrected. </item>
	    <item> Minor corrections of documentation and type
	    specifications of app() and mod() are done. </item>
	    <item> If a module name is duplicated in an app file
	    reltool would return an error. This is now changed to a
	    warning. </item> <item> Reltool would earlier not
	    necessarily keep the order of applications as listed in
	    the rel specification in the configuration. This has been
	    corrected. </item> <item> Reltool would earlier set the
	    default for included applications to an empty list if it
	    was not set in the rel specification in the
	    configuration. This was correct according to
	    sasl/systools documentation, but not according to
	    sasl/systools implementation. We decided to change the
	    documentation and reltool to use the value of
	    included_applications from the .app file as default
	    instead of the empty list, since this seems more
	    intuitive and since systools always has done the same.
	    </item> <item> The value of included applications in the
	    rel specification in the configuration did not overwrite
	    included_applications in the .app file if it was set to
	    an empty list. This has been corrected. </item> <item>
	    Reltool would earlier add load instructions in the
	    script/boot files for ALL modules in the ebin directory
	    of an application even if mod_cond was set to app
	    (include only modules listed in the .app file). This has
	    been corrected. </item> <item> Reltool would earlier add
	    start instructions in the script/boot file for included
	    applications. This has been corrected - included
	    applications shall only be loaded since the including
	    application is responsible for starting them. </item>
	    <item> Status bar now indicates that reltool is working
	    (Processing libraries...) for all configuration changes,
	    and when generating target system. </item> <item> Title
	    of dependecies column in app and mod window is changed
	    from "Modules used by others" to "Modules using this".

	    Configuration changes via the GUI had a few bugs related
	    to error handling, rollback and undo. A major re-write of
	    the reltool_server has been done in order to align the
	    way reltool_server updates and uses its state and tables
	    for all different kinds of configuration change. </p>
          <p>
	    All configuration changes (except undo) now cause a
	    re-read of the file system, meaning that if something has
	    changed in the file system it will be reflected in the
	    result of the configuration change.</p>
          <p>
	    When loading a new configuration file via the GUI, the
	    old configuration is now completely scratched, and only

	    Some bug fixes related to the handling of escripts:</p>
	    <list> <item> Reltool could not handle escripts with
	    inlined applications. This has been corrected. Inlined
	    applications will be visible in the GUI, but not possible
	    to include/exclude separately. </item> <item> Loading a
	    config which contains an escript via the GUI menu did not
	    produce the same result as when using the same
	    configuration at reltool start. Paths, version and label
	    could differ. This has been corrected. </item> <item>
	    Loading config with same escript (source) twice caused
	    reltool to add same module twice. This has been
	    corrected. </item> <item> Loading config with same
	    escript (inlined beam) twice caused reltool to fail
	    saying module is included by two different applications.
	    This has been corrected. </item> <item> Loading config
	    which in addition to an existing escript also adds
	    another escript, for which the name sorts before the
	    existing one, would cause reltool to fail saying
	    "Application name clash". This has been corrected.

	    Reltool would sometimes generate a .app file containing

	    exception in systools at parse time. This has been

	    As a way of specifying one specific version of an
	    application, the following configuration parameter is
	    added on application level:</p>
          <p>
	    {lib_dir,Dir}, Dir = string()</p>
          <p>
	    This can be useful if the parent directory of the
	    application directory is not suitable to use as a lib dir
	    on system level.</p>

	    If a module was duplicated in the library directories

            Added function <c>zip:foldl/3</c> to iterate over zip

            Added functions to create and extract escripts. See

          <p>
            The undocumented function <c>escript:foldl/3</c> has been

            Record fields has been annotated with type info. Source

            <p>A new escript, called <c>reltool</c>, has been
            introduced in order to simplify the usage of the reltool
            application from makefiles.</p>
            <p>The handling of applications included in releases has
            been improved. Applications that are required to be
            started before other applications in a release are now
            automatically included in the release. The Kernel
            and STDLIB applications are always included as
            they are mandatory.</p>
            <p>Applications that are (explicitly or implicitly)
            included in a release are now automatically included as
            if they were explicitly included with the incl_cond
            flag.</p>
            <p>A new <c>embedded_app_type</c> option has been
            introduced. It is intended to be used for embedded
            systems where all included applications must be loaded
            from the boot script, as these systems does not utilize
            dynamic code loading. If <c>embedded_app_type </c> is set
            to something else than <c>undefined</c>, all included
            applications will be included in both the release as well
            as in the boot script. If the <c>profile</c> is
            <c>embedded</c> the <c>embedded_app_type</c> option
            defaults to <c>load</c>.</p>
            <p>A new function called <c>reltool:get_status/1</c> has
            been introduced. It returns status about the
            configuration in the server.</p>
            <p>The API functions that may take <c>PidOrOptions</c> as
            input and actually gets <c>Options</c> does now print out
            warnings.</p>
            <p>The internal error handling has been improved. For
            example <c>{error,Reason}</c> is always returned in case
            of errors even when the server dies.</p>
            <p><c>app</c> and <c>appup</c> files has been added as
            well as a corresponding test suite.</p>
            <p>Various cleanups has been made in the code and in the
            documentation.</p>

                In the new release of Reltool (0.5) there is a severe bug
                that may cause your source files to be deleted. The bug
                is triggered when you generate a target system WITH
                archive files AND your library directories are given with
                absolute paths. (Library directories are given with the
                ERL_LIBS environment variable or with the lib_dirs
                configuration parameter.)</p>

                Major improvements of the target system generation has
                been performed. Now it is possible to generate a
                relocatable target system that does not need to be
                re-installed if it is moved to a new location. Archive
                files are automatically generated. A detailed
                specification of the target system can be generated
                without actually creating the target system. Relocatable
                escripts are put in the bin directory of the target
                system. etc. etc.</p>
              <p>
                Some new functions has been introduced in the
                <c>reltool</c> module: <c>start/1, start_link/1,
                get_config/3, get_target_spec/1 and
                eval_target_spec/3</c>.</p>
              <p>
                Some new configuration parameters has been introduced:
                <c>profile, incl_sys_filters, excl_sys_filters,
                incl_app_filters, excl_app_filters, incl_archive_filters,
                excl_archive_filters, archive_opts, escript and
                relocatable</c>.</p>
              <p>
                Some parameters have been obsoleted and given new
                semantics: <c>incl_erts_dirs (incl_sys_filters),
                excl_erts_dirs (excl_sys_filters), incl_app_dirs
                (incl_app_filters), excl_app_dirs (excl_app_filters) and
                escripts (escript).</c></p>
