60	<li class="new">Fill in a pacman cache for CMT using pacman3
61	syntax. The Pacman package name is CMT.</li>
62
63	<li class="new">Extend the recursive checkout mechanism to
64	projects. The recursivity covers the use relationships
65	between projects and propagates to packges of a project when
66	the container package is specified in the project file.</li>
67
68	<li class="new">Add the cvssubprojects query command to
69	retrieve subprojects at a CVS repository level</li>
70
71	<li class="new">Add a container statement in project
72	file. The syntax is like use statements. It indicates that a
73	container-like package exists in the project. This is useful
74	for recursive checkout operations.</li>
75
76	<li class="int">Migrate to a new version of the CVS
77	pluggin. Now the protocol level is explicitly referenced
78	when sending CVS requests via the pluggin. The new protocol
79	gives the nature of the CVS module: is it a project or a
80	package. The protocol level is specified in a dedicated
81	macro in the CMT requirements file.</li>
82
83	<li class="bug">Fix the production of shared libraries on CYGWIN</li>
84
85	<li class="bug">Fix ambiguities between physical paths and
86	logical paths in PATH variables management</li>

106
107	<li class="new">Accept HEAD or head as a valid version tag for packages</li>
108
109	<li class="new">The path of CMT is removed from
110	CMTPATH. Packages aside CMT are no longer reachable by
111	default</li>
112
113	<li class="new">Major restructuring of the project
114	management and package localisation. The most important
115	parameter becomes the search path CMTPROJECTPATH for
116	projects. Then CMTPATH is deduced from the effective list of
117	used projects. Project files and the dependency graph
118	described by the project use statement becomes a central
119	mechanism.</li>
120
121	<li class="new">Introduce the management of releases for
122	projects. Release must exactly match</li>

124	<li class="new">Install a mechanism to detect unused tags
125	from arguments or CMTSITE. This is performed during the

165
166	<li class="int">Suppress the completely unused makefile strategy</li>
167
168	<li class="bug">Really apply the project specific setup
169	strategy to control the generation of ROOT or CONFIG
170	env. variables.</li>
171
172	<li class="new">Change default build strategy to <tt>without_installarea</tt></li>
173
174	<li class="new">${CMTROOT} is no longer an automatic part of
175	the CMTPATH. Nor the current package automatically defines
176	an entry in the CMTPATH search list. However a feature
177	partly compensates this evolution: the current project
178	(i.e. the current package area, where the developer stands)
179	is autmatically detected when its project file exists
180	(i.e. when its cmt/project.cmt file exists). For instance,
181	this suppresses the need to set CMTPATH when working in one
182	single project.</li>
183
184	<li class="new">The general cmt command parsing mechanism
185	has been revisited and now "actions" are considered as
186	extended cmt commands and no longer need the "cmt do
187	<action>" syntax. One can directly use "cmt
188	<action>" when the action does not conflict with
189	internal cmt commands.</li>
190
191	<li class="new">Command line arguments are transmitted to
192	"actions" now through the new standard "cmt_args" macro</li>
193
194	<li class="bug">Really force the settings of all
195	Env. variables before running internal cmmands through
196	broadcast, run or do commands.</li>
197
198	<li class="new">The "cmt run" command transmits all its
199	arguments to the launched action</li>
200
201	<li class="new">Revisit the production of dependency files,
202	to consider the changes made to the configuration in general
203	in addition to the usual source changes. This consists in
204	generating one stamp file per source, touched when its
205	contents change rather than when recomputing the
206	dependencies.</li>
207
208	<li class="bug">Better protections for CMTPATH entries</li>
209
210	<li class="int">Major internal restructuring of the CMT
211	package. Internal sources are now in ../source, ../src only
212	contains publicly exported configuration files, fragments
213	are in ../mgr/fragments. This is for constructing a really
214	autonomous binary kit for CMT (eg for Fink) (without needing
215	to export two kits)</li>
216
217	<li class="bug">Now produce the last revision date of the
218	CMT documentation. Insert the complete version tag rather
219	than just the base version tag.</li>
220
221	<li class="new">Suppress the systematic production of
222	bundles on Darwin machines. This must now be done
223	explicitly.</li>
224
225	<li class="bug">The algorithm for commpressing paths with
226	../ patterns now takes into account the presence of ${xxx}
227	expressions that cannot be reduced. It also better handle
228	various patterns that used to produce failures.</li>
229
230	<li class="bug">A global checking of the configuration is
231	performed first when running Make</li>
232
233	<li class="new">Incompatible major ids in the version
234	numbers are now managed like the minor id, ie. the decision
235	is taken in a similar way. The usual error message is
236	displayed but this is no longer fatal, and a decision is
237	taken</li>

266	<li class="new">Introduce a new -strict option to the cmt
267	expand model to support model files freely formatted. This
268	implied securing the user defined model elements by the
269	<tt>cmts</tt> or <tt>cmtv</tt> name space
270	keywords. <tt>cmts:xxx</tt> indicates a scalar modelling
271	element <tt>xxx</tt> meant to be expanded only

273	<tt>yyy</tt> meant to be expanded once per item in the

531	<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>
532	<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>
533	<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>
534	<li class="new">add a command "cmt show cycles" to display circular dependencies in the use graph.</li>
535	<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>
536	<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>
537	<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>
538	<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:
539	<pre>
540	> cmt --public ...
541	</pre>
542	only sees public uses (default behavior for most commands but not for cmt broadcast and cmt show uses which traverse the private sub graphs)
543	<pre>
544	> cmt --private ...
545	</pre>
546	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>
547	<li class="bug">A global pattern specifying private sections did not really generate private definitions</li>
