59
60	<li class="int">Suppress the completely unused makefile strategy</li>
61
62	<li class="bug">Really apply the project specific setup
63	strategy to control the generation of ROOT or CONFIG
64	env. variables.</li>
65
66	<li class="new">Change default build strategy to <tt>without_installarea</tt></li>
67
68	<li class="new">${CMTROOT} is no longer an automatic part of
69	the CMTPATH. Nor the current package automatically defines
70	an entry in the CMTPATH search list. However a feature
71	partly compensates this evolution: the current project
72	(i.e. the current package area, where the developer stands)
73	is autmatically detected when its project file exists
74	(i.e. when its cmt/project.cmt file exists). For instance,
75	this suppresses the need to set CMTPATH when working in one
76	single project.</li>
77
78	<li class="new">The general cmt command parsing mechanism
79	has been revisited and now "actions" are considered as
80	extended cmt commands and no longer need the "cmt do
81	<action>" syntax. One can directly use "cmt
82	<action>" when the action does not conflict with
83	internal cmt commands.</li>
84
85	<li class="new">Command line arguments are transmitted to
86	"actions" now through the new standard "cmt_args" macro</li>
87
88	<li class="bug">Really force the settings of all
89	Env. variables before running internal cmmands through
90	broadcast, run or do commands.</li>
91
92	<li class="new">The "cmt run" command transmits all its
93	arguments to the launched action</li>
94
95	<li class="new">Revisit the production of dependency files,
96	to consider the changes made to the configuration in general
97	in addition to the usual source changes. This consists in
98	generating one stamp file per source, touched when its
99	contents change rather than when recomputing the
100	dependencies.</li>
101
102	<li class="bug">Better protections for CMTPATH entries</li>
103
104	<li class="int">Major internal restructuring of the CMT
105	package. Internal sources are now in ../source, ../src only
106	contains publicly exported configuration files, fragments
107	are in ../mgr/fragments. This is for constructing a really
108	autonomous binary kit for CMT (eg for Fink) (without needing
109	to export two kits)</li>
110
111	<li class="bug">Now produce the last revision date of the
112	CMT documentation. Insert the complete version tag rather
113	than just the base version tag.</li>
114
115	<li class="new">Suppress the systematic production of
116	bundles on Darwin machines. This must now be done
117	explicitly.</li>
118
119	<li class="bug">The algorithm for commpressing paths with
120	../ patterns now takes into account the presence of ${xxx}
121	expressions that cannot be reduced. It also better handle
122	various patterns that used to produce failures.</li>
123
124	<li class="bug">A global checking of the configuration is
125	performed first when running Make</li>
126
127	<li class="new">Incompatible major ids in the version
128	numbers are now managed like the minor id, ie. the decision
129	is taken in a similar way. The usual error message is
130	displayed but this is no longer fatal, and a decision is
131	taken</li>

146	-->
147
148	<li class="new">Introduce the support of SLC3 (Scientific
149	Linux) platforms</li>
150
151	<li class="new">Trigger the reconstruction of the dependency
152	makefile fragment from a change in the
153	<package>_setup.make, ie from any change in tags, uses
154	or CMTPATHs</li>
155
156	<li class="new"><tt>CMTBIN</tt> now follows a new convention
157	on Unix `uname`-`uname -m` to differentiate among Linux
158	platforms.</li>
159
160	<li class="new">Introduce a new -strict option to the cmt
161	expand model to support model files freely formatted. This
162	implied securing the user defined model elements by the
163	<tt>cmts</tt> or <tt>cmtv</tt> name space
164	keywords. <tt>cmts:xxx</tt> indicates a scalar modelling
165	element <tt>xxx</tt> meant to be expanded only
166	once. <tt>cmtv:yyy</tt> indicates a vector modelling element
167	<tt>yyy</tt> meant to be expanded once per item in the
168	vector of values.</li>
169
170	<li class="new">Better management of temporary file
171	generation. Now support the standard TMPDIR environment
172	variable to redirect temporary locations.</li>
173
174	<li class="int">Apply the new GPL-like licence officially
175	provided by CNRS-CEA-INRIA</li>
176
177	<li class="int">Use stderr instead of stdout to display
178	error and warning messages. Mainly to better expose messages in
179	the source setup operations</li>
180
181	<li class="bug">Protect against source files not found (avoid infinite loops in make)</li>
182
183	<li class="bug">Better management of the build strategy on
184	installation area to generate various automatic macros or
185	sets (installarea_linkopts, PATH, LD_LIBRARY_PATH,
186	etc...)</li>
187
188	<li class="bug">Revisit the package scan algorithm to
189	improve the detection of directory structure of packages as
190	well as their version tags.</li>
191
192	<li class="bug">Compress the path definitions (ie compress
193	the ../xxx patterns) and use the compressed paths
194	everywhere</li>

231	<li class="new">Generate the <tt>target_${CONSTITUENT}</tt>
232	tag to trigger configuration control per target. This
233	feature is only activated when the new <tt>-target_tag</tt>
234	option is specified to a constituent. Specific tag makefiles
235	are then generated for those targets. This tag is activated

411	<li class="new">The broadcast pattern as well as the standard macro <cmtpath> is now renamed <package_cmtpath> to avoid confusion with the CMTPATH variable on Windows.</li>
412	<li class="int">Make use of ${PWD} when available to acquire the value for "cmt show pwd"</li>

422	<b>v1r14p20030620</b>
423	<ul>
424	<li class="new">introduce a generic "Unix" tag for all Unix platforms. Both Linux, HP-UX, LynxOS, alpha, ... do validate Unix</li>
425	<li class="new">hide the make_fragments declaration in private sections. This was not true previously. A make_fragment declaration installed in a private section will now be hidden to clients.</li>
426	<li class="bug">convert ${} into $() syntax for tag makefiles on Windows. This actually reverts to a feature of an old CMT version which had disappeared. This was causing a problem since the ${} syntax is not understood by nmake</li>
427	<li class="new">add a command "cmt show use_paths <target>" to display all possible paths to the target package. This is useful to understand how a given package is reached, for instance when it is desired to cut the use relationship and make it private somewhere in the graph.</li>
428	<li class="new">add a command "cmt show cycles" to display circular dependencies in the use graph.</li>
429	<li class="new">provide a binary RPM for CMT itself (only for redhat 7.2 distribution). It is downloadable from the usual Download page and provide a complete installation of CMT (including make fragments, binary, etc..). It is a relocatable RPM (install it using the --relocate option). (See the install WEB page for complete notice)</li>
430	<li class="new">Add an extended script to retrieve information about Linux version (cmt_linux_version.sh). It supports Redhat, Debian, Suse. It is used to compute the cmt_system_version macro (contributions from Clark McGrew and Wim Lavrijsen)</li>
431	<li class="bug">The setup scripts for Windows now use %TEMP% instead of %HOMEDRIVE%%HOMEPATH% to store temporary files (contributions from Pere Mato and Florence Ranjard)</li>
432	<li class="new">Add the --public and --private global options for cmt commands, to control whether the use graph traverses or not the private sections:
433	<pre>
434	> cmt --public ...
435	</pre>
436	only sees public uses (default behavior for most commands but not for cmt broadcast and cmt show uses which traverse the private sub graphs)
437	<pre>
438	> cmt --private ...
439	</pre>
440	forces the traversal of private subgraphs. This is already the default behavior for cmt show uses and for cmt broadcast, but can now be applied to any CMT command.</li>
441	<li class="bug">A global pattern specifying private sections did not really generate private definitions</li>
