62	the specification of the structuring style or of the
63	structuring strategy.</li>
64
65	<li class="new">Introduce a new strategy structure_strategy
66	with only one value with/out_version_directory. This is
67	mostly useful when installed in a project file to condition
68	the behaviour of package creation afterwards</li>
69
70	<li class="new">Support dependency building using external
71	tools such as cpp -M. Fix the cmt_build_des.sh wrapper
72	script to properly format the command output.</li>

75	if the basic directory structure of the project is already
76	in place.</li>

78	<li class="new">When no current project is defined the
79	strategies are taken from the top project (eg obtained from

97
98	<li class="bug">When creating a parent-less project, link it
99	to exisiting top project(s) and upgrade strategies

134	<li class="new">Fill in a pacman cache for CMT using pacman3
135	syntax. The Pacman package name is CMT.</li>
136
137	<li class="new">Extend the recursive checkout mechanism to
138	projects. The recursivity covers the use relationships
139	between projects and propagates to packges of a project when
140	the container package is specified in the project file.</li>
141
142	<li class="new">Add the cvssubprojects query command to
143	retrieve subprojects at a CVS repository level</li>
144
145	<li class="new">Add a container statement in project
146	file. The syntax is like use statements. It indicates that a
147	container-like package exists in the project. This is useful
148	for recursive checkout operations.</li>
149
150	<li class="int">Migrate to a new version of the CVS
151	pluggin. Now the protocol level is explicitly referenced
152	when sending CVS requests via the pluggin. The new protocol
153	gives the nature of the CVS module: is it a project or a
154	package. The protocol level is specified in a dedicated
155	macro in the CMT requirements file.</li>

181	<li class="new">Accept HEAD or head as a valid version tag for packages</li>
182
183	<li class="new">The path of CMT is removed from
184	CMTPATH. Packages aside CMT are no longer reachable by
185	default</li>
186
187	<li class="new">Major restructuring of the project
188	management and package localisation. The most important
189	parameter becomes the search path CMTPROJECTPATH for
190	projects. Then CMTPATH is deduced from the effective list of
191	used projects. Project files and the dependency graph
192	described by the project use statement becomes a central
193	mechanism.</li>
194
195	<li class="new">Introduce the management of releases for
196	projects. Release must exactly match</li>

239
240	<li class="int">Suppress the completely unused makefile strategy</li>
241
242	<li class="bug">Really apply the project specific setup
243	strategy to control the generation of ROOT or CONFIG
244	env. variables.</li>
245
246	<li class="new">Change default build strategy to <tt>without_installarea</tt></li>
247
248	<li class="new">${CMTROOT} is no longer an automatic part of
249	the CMTPATH. Nor the current package automatically defines
250	an entry in the CMTPATH search list. However a feature
251	partly compensates this evolution: the current project
252	(i.e. the current package area, where the developer stands)
253	is autmatically detected when its project file exists
254	(i.e. when its cmt/project.cmt file exists). For instance,
255	this suppresses the need to set CMTPATH when working in one
256	single project.</li>
257
258	<li class="new">The general cmt command parsing mechanism
259	has been revisited and now "actions" are considered as
260	extended cmt commands and no longer need the "cmt do
261	<action>" syntax. One can directly use "cmt
262	<action>" when the action does not conflict with
263	internal cmt commands.</li>
264
265	<li class="new">Command line arguments are transmitted to
266	"actions" now through the new standard "cmt_args" macro</li>
267
268	<li class="bug">Really force the settings of all
269	Env. variables before running internal cmmands through
270	broadcast, run or do commands.</li>
271
272	<li class="new">The "cmt run" command transmits all its
273	arguments to the launched action</li>
274
275	<li class="new">Revisit the production of dependency files,
276	to consider the changes made to the configuration in general
277	in addition to the usual source changes. This consists in
278	generating one stamp file per source, touched when its
279	contents change rather than when recomputing the
280	dependencies.</li>
281
282	<li class="bug">Better protections for CMTPATH entries</li>
283
284	<li class="int">Major internal restructuring of the CMT
285	package. Internal sources are now in ../source, ../src only
286	contains publicly exported configuration files, fragments
287	are in ../mgr/fragments. This is for constructing a really
288	autonomous binary kit for CMT (eg for Fink) (without needing
289	to export two kits)</li>
290
291	<li class="bug">Now produce the last revision date of the
292	CMT documentation. Insert the complete version tag rather
293	than just the base version tag.</li>
294
295	<li class="new">Suppress the systematic production of
296	bundles on Darwin machines. This must now be done
297	explicitly.</li>
298
299	<li class="bug">The algorithm for commpressing paths with
300	../ patterns now takes into account the presence of ${xxx}
301	expressions that cannot be reduced. It also better handle
302	various patterns that used to produce failures.</li>
303
304	<li class="bug">A global checking of the configuration is
305	performed first when running Make</li>
306
307	<li class="new">Incompatible major ids in the version
308	numbers are now managed like the minor id, ie. the decision
309	is taken in a similar way. The usual error message is
310	displayed but this is no longer fatal, and a decision is
311	taken</li>

341	expand model to support model files freely formatted. This
342	implied securing the user defined model elements by the
343	<tt>cmts</tt> or <tt>cmtv</tt> name space
344	keywords. <tt>cmts:xxx</tt> indicates a scalar modelling

604	<li class="new">introduce a generic "Unix" tag for all Unix platforms. Both Linux, HP-UX, LynxOS, alpha, ... do validate Unix</li>
605	<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>
606	<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>
607	<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>

609	<li class="new">provide a binary RPM for CMT itself (only for redhat 7.2 distribution).

617	<pre>
618	> cmt --private ...
