61
62	<li class="new">Accept HEAD or head as a valid version tag for packages</li>
63
64	<li class="new">The path of CMT is removed from
65	CMTPATH. Packages aside CMT are no longer reachable by
66	default</li>
67
68	<li class="new">Major restructuring of the project
69	management and package localisation. The most important
70	parameter becomes the search path CMTPROJECTPATH for
71	projects. Then CMTPATH is deduced from the effective list of
72	used projects. Project files and the dependency graph
73	described by the project use statement becomes a central
74	mechanism.</li>
75
76	<li class="new">Introduce the management of releases for
77	projects. Release must exactly match</li>
78
79	<li class="new">Install a mechanism to detect unused tags
80	from arguments or CMTSITE. This is performed during the
81	setup generation</li>

120
121	<li class="int">Suppress the completely unused makefile strategy</li>
122
123	<li class="bug">Really apply the project specific setup
124	strategy to control the generation of ROOT or CONFIG
125	env. variables.</li>
126
127	<li class="new">Change default build strategy to <tt>without_installarea</tt></li>
128
129	<li class="new">${CMTROOT} is no longer an automatic part of
130	the CMTPATH. Nor the current package automatically defines
131	an entry in the CMTPATH search list. However a feature
132	partly compensates this evolution: the current project
133	(i.e. the current package area, where the developer stands)
134	is autmatically detected when its project file exists
135	(i.e. when its cmt/project.cmt file exists). For instance,
136	this suppresses the need to set CMTPATH when working in one
137	single project.</li>
138
139	<li class="new">The general cmt command parsing mechanism
140	has been revisited and now "actions" are considered as
141	extended cmt commands and no longer need the "cmt do
142	<action>" syntax. One can directly use "cmt
143	<action>" when the action does not conflict with
144	internal cmt commands.</li>
145
146	<li class="new">Command line arguments are transmitted to
147	"actions" now through the new standard "cmt_args" macro</li>
148
149	<li class="bug">Really force the settings of all
150	Env. variables before running internal cmmands through
151	broadcast, run or do commands.</li>
152
153	<li class="new">The "cmt run" command transmits all its
154	arguments to the launched action</li>
155
156	<li class="new">Revisit the production of dependency files,
157	to consider the changes made to the configuration in general
158	in addition to the usual source changes. This consists in
159	generating one stamp file per source, touched when its
160	contents change rather than when recomputing the
161	dependencies.</li>
162
163	<li class="bug">Better protections for CMTPATH entries</li>
164
165	<li class="int">Major internal restructuring of the CMT
166	package. Internal sources are now in ../source, ../src only
167	contains publicly exported configuration files, fragments
168	are in ../mgr/fragments. This is for constructing a really
169	autonomous binary kit for CMT (eg for Fink) (without needing
170	to export two kits)</li>
171
172	<li class="bug">Now produce the last revision date of the
173	CMT documentation. Insert the complete version tag rather
174	than just the base version tag.</li>
175
176	<li class="new">Suppress the systematic production of
177	bundles on Darwin machines. This must now be done
178	explicitly.</li>
179
180	<li class="bug">The algorithm for commpressing paths with
181	../ patterns now takes into account the presence of ${xxx}
182	expressions that cannot be reduced. It also better handle
183	various patterns that used to produce failures.</li>
184
185	<li class="bug">A global checking of the configuration is
186	performed first when running Make</li>
187
188	<li class="new">Incompatible major ids in the version
189	numbers are now managed like the minor id, ie. the decision
190	is taken in a similar way. The usual error message is
191	displayed but this is no longer fatal, and a decision is
192	taken</li>

215	or CMTPATHs</li>
216

218	on Unix `uname`-`uname -m` to differentiate among Linux
219	platforms.</li>
220
221	<li class="new">Introduce a new -strict option to the cmt
222	expand model to support model files freely formatted. This
223	implied securing the user defined model elements by the
224	<tt>cmts</tt> or <tt>cmtv</tt> name space
225	keywords. <tt>cmts:xxx</tt> indicates a scalar modelling
226	element <tt>xxx</tt> meant to be expanded only

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