<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>
<section><title>Reltool 0.5.6</title>
<section><title>Fixed Bugs and Malfunctions</title>
<list>
<item>
<p>
The system level option <c>app_files</c> is documented to
allow the values <c>keep | strip | all</c>, but it only
allowed <c>keep</c>. This is corrected.</p>

Allow the same module name in multiple applications
visible to reltool, as long as all but one of the
applications/modules are explicitely excluded. (Thanks to
Andrew Gopienko and Jay Nelson)</p>

<section><title>Fixed Bugs and Malfunctions</title>
<list>

<p>
The reltool module contained two seriously erroneous
specs which caused bogus warnings when dialyzing reltool
and some correct code of users. These were fixed (specs
for start_link/1 and eval_server/3)</p>
<p>
- Code cleanups and simplifications - Fix a bug in the
calculation of circular dependencies - Eliminate two
dialyzer warnings - Put files alphabetically</p>

<section><title>Improvements and New Features</title>
<list>
<item>
<p>
Added function <c>zip:foldl/3</c> to iterate over zip
archives.</p>
<p>
Added functions to create and extract escripts. See
<c>escript:create/2</c> and <c>escript:extract/2</c>.</p>
<p>
The undocumented function <c>escript:foldl/3</c> has been
removed. The same functionality can be achieved with the
more flexible functions <c>escript:extract/2</c> and
<c>zip:foldl/3</c>.</p>
<p>
Record fields has been annotated with type info. Source
files as been adapted to fit within 80 chars and trailing
whitespace has been removed.</p>

<item>
<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 <c>kernel</c>
and <c>stdlib</c> 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>

visible change is that the HTML frames are removed.</p>

<item>
<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>

<p>
The tool is still experimental. Feedback is appreciated. </p>
<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>
