59
60 <li class="new">Support dependency building using external
61 tools such as cpp -M. Fix the cmt_build_des.sh wrapper
62 script to properly format the command output.</li>
63
64 <li class="new">Perform the cmt checkout onto a project even
65 if the basic directory structure of the project is already
66 in place.</li>
67
68 <li class="new">When no current project is defined the
69 strategies are taken from the top project (eg obtained from
70 the CMTPATH)</li>
71
72 <li class="new">The include_dirs statement can now be hidden
73 in a private section.</li>
74
75 <li class="new">The include_dirs statement now accepts a
76 macro reference as its value</li>
77

79
80 <li class="bug">Fix incorrect generation of XXXROOT and
81 XXXCONFIG environment variables according to strategies</li>
82
83 <li class="bug">Protect against missing un/install targets</li>
84
85 <li class="bug">Fix a typo in cmt_uninstall_action.bat
86 resulting in bad management of make cleanup on Windows</li>
87
88 <li class="bug">When creating a parent-less project, link it
89 to exisiting top project(s) and upgrade strategies
90 accordingly. Avoid confusions when mixing explicit CMTPATH,
91 CMTPROJECTPATH and project files </li>
92
93 <li class="bug">Don't apply include_dirs when their expanded
94 value is empty (avoid killing -I"")</li>
95
96 <li class="bug">Reset CMTPATH to empty when filling in
97 CMTPATH from projects (avoid confusions and
98 dupplications)</li>

124 <li class="new">Fill in a pacman cache for CMT using pacman3
125 syntax. The Pacman package name is CMT.</li>
126
127 <li class="new">Extend the recursive checkout mechanism to
128 projects. The recursivity covers the use relationships
129 between projects and propagates to packges of a project when
130 the container package is specified in the project file.</li>
131
132 <li class="new">Add the cvssubprojects query command to
133 retrieve subprojects at a CVS repository level</li>
134
135 <li class="new">Add a container statement in project
136 file. The syntax is like use statements. It indicates that a
137 container-like package exists in the project. This is useful
138 for recursive checkout operations.</li>
139
140 <li class="int">Migrate to a new version of the CVS
141 pluggin. Now the protocol level is explicitly referenced
142 when sending CVS requests via the pluggin. The new protocol
143 gives the nature of the CVS module: is it a project or a
144 package. The protocol level is specified in a dedicated
145 macro in the CMT requirements file.</li>

170
171 <li class="new">Accept HEAD or head as a valid version tag for packages</li>
172
173 <li class="new">The path of CMT is removed from
174 CMTPATH. Packages aside CMT are no longer reachable by
175 default</li>
176
177 <li class="new">Major restructuring of the project
178 management and package localisation. The most important
179 parameter becomes the search path CMTPROJECTPATH for
180 projects. Then CMTPATH is deduced from the effective list of
181 used projects. Project files and the dependency graph
182 described by the project use statement becomes a central
183 mechanism.</li>
184
185 <li class="new">Introduce the management of releases for
186 projects. Release must exactly match</li>
187
188 <li class="new">Install a mechanism to detect unused tags
189 from arguments or CMTSITE. This is performed during the
190 setup generation</li>

228 -->
229
230 <li class="int">Suppress the completely unused makefile strategy</li>
231
232 <li class="bug">Really apply the project specific setup
233 strategy to control the generation of ROOT or CONFIG
234 env. variables.</li>
235
236 <li class="new">Change default build strategy to <tt>without_installarea</tt></li>
237
238 <li class="new">${CMTROOT} is no longer an automatic part of
239 the CMTPATH. Nor the current package automatically defines
240 an entry in the CMTPATH search list. However a feature
241 partly compensates this evolution: the current project
242 (i.e. the current package area, where the developer stands)
243 is autmatically detected when its project file exists
244 (i.e. when its cmt/project.cmt file exists). For instance,
245 this suppresses the need to set CMTPATH when working in one
246 single project.</li>
247
248 <li class="new">The general cmt command parsing mechanism
249 has been revisited and now "actions" are considered as
250 extended cmt commands and no longer need the "cmt do
251 &lt;action&gt;" syntax. One can directly use "cmt
252 &lt;action&gt;" when the action does not conflict with
253 internal cmt commands.</li>
254
255 <li class="new">Command line arguments are transmitted to
256 "actions" now through the new standard "cmt_args" macro</li>
257
258 <li class="bug">Really force the settings of all
259 Env. variables before running internal cmmands through
260 broadcast, run or do commands.</li>
261
262 <li class="new">The "cmt run" command transmits all its
263 arguments to the launched action</li>
264
265 <li class="new">Revisit the production of dependency files,
266 to consider the changes made to the configuration in general
267 in addition to the usual source changes. This consists in
268 generating one stamp file per source, touched when its
269 contents change rather than when recomputing the
270 dependencies.</li>
271
272 <li class="bug">Better protections for CMTPATH entries</li>
273
274 <li class="int">Major internal restructuring of the CMT
275 package. Internal sources are now in ../source, ../src only
276 contains publicly exported configuration files, fragments
277 are in ../mgr/fragments. This is for constructing a really
278 autonomous binary kit for CMT (eg for Fink) (without needing
279 to export two kits)</li>
280
281 <li class="bug">Now produce the last revision date of the
282 CMT documentation. Insert the complete version tag rather
283 than just the base version tag.</li>
284
285 <li class="new">Suppress the systematic production of
286 bundles on Darwin machines. This must now be done
287 explicitly.</li>
288
289 <li class="bug">The algorithm for commpressing paths with
290 ../ patterns now takes into account the presence of ${xxx}
291 expressions that cannot be reduced. It also better handle
292 various patterns that used to produce failures.</li>
293
294 <li class="bug">A global checking of the configuration is
295 performed first when running Make</li>
296
297 <li class="new">Incompatible major ids in the version
298 numbers are now managed like the minor id, ie. the decision
299 is taken in a similar way. The usual error message is
300 displayed but this is no longer fatal, and a decision is
301 taken</li>

328 platforms.</li>
329
330 <li class="new">Introduce a new -strict option to the cmt
331 expand model to support model files freely formatted. This
332 implied securing the user defined model elements by the
333 <tt>cmts</tt> or <tt>cmtv</tt> name space
334 keywords. <tt>cmts:xxx</tt> indicates a scalar modelling

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

581 <li class="new">The broadcast pattern as well as the standard macro &lt;cmtpath&gt; is now renamed &lt;package_cmtpath&gt; to avoid confusion with the CMTPATH variable on Windows.</li>
582 <li class="int">Make use of ${PWD} when available to acquire the value for "cmt show pwd"</li>
583 <li class="bug">Add or refresh tuning for CYGWIN and for LynxOS</li>
584 <li class="bug">Work around a limitation of some old version of the C++ compiler on LynxOS</li>
585 <li class="new">Improve the display of incompatible use specifications.</li>
586 <li class="int">Dynamically create the CMTDownload.html web page to really reflect what is available when installing the CMT release on the primary CMT web site.</li>
587 <li class="bug">Setup.bat scripts on DOS are now relocatable wrt heterogeneous file systems (AFS, DFS, etc...)</li>

593 <ul>
594 <li class="new">introduce a generic "Unix" tag for all Unix platforms. Both Linux, HP-UX, LynxOS, alpha, ... do validate Unix</li>
595 <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>
596 <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>
597 <li class="new">add a command "cmt show use_paths &lt;target&gt;" 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>
598 <li class="new">add a command "cmt show cycles" to display circular dependencies in the use graph.</li>
599 <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>
600 <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>
601 <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>
602 <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:
603<pre>
604&gt; cmt --public ...
605</pre>
606 only sees public uses (default behavior for most commands but not for cmt broadcast and cmt show uses which traverse the private sub graphs)
607<pre>
608&gt; cmt --private ...
609</pre>
610 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>
611 <li class="bug">A global pattern specifying private sections did not really generate private definitions</li>
