3	<!-- Release change log structure
4
5	Each release has a matching log of changes which were made for that and
6	earlier releases. Earlier releases means anything with a lower number (e.g.
7	5.0.18 is lower than 5.1.2) which was released before this one. The log is
8	kept in the file doc/manual/user_ChangeLogImpl.xml. Anything worth mentioning,
9	particularly new features and fixed bugs, with a trac bug number if possible,
10	should be added to the top of the change log (that is, the section for the
11	upcoming release) for the branch in which it first appears - stable or
12	development - before the next release. If you back-port it to older branches
13	please add an entry there too. When a new major release is made, change log
14	sections for earlier releases are merged in.
15
16	Change log sections are split into two groups: major new features (normally
17	only for dot zero releases) and fixes. In addition, the entries in each group
18	are ordered as follows:
19
20	VMM-related entries (most important)
21	GUI-related entries (most visible for users)
22	Device-related entries
23	VBoxManage/API/Main-related entries
24	Host-related entries
25	Guest-related entries -->

27	<chapter> <!-- HACK ALERT! Seems we must have a single top level element for xi:include to work.
28	So, we use chapter and xpointer="xpointer(/chapter/)" with xi:include. -->
