2<!-- Release change log structure
3
4Each release has a matching log of changes which were made for that and
5earlier releases. Earlier releases means anything with a lower number (e.g.
65.0.18 is lower than 5.1.2) which was released before this one. The log is
7kept in the file doc/manual/user_ChangeLogImpl.xml. Anything worth mentioning,
8particularly new features and fixed bugs, with a trac bug number if possible,
9should be added to the top of the change log (that is, the section for the
10upcoming release) for the branch in which it first appears - stable or
11development - before the next release. If you back-port it to older branches
12please add an entry there too. When a new major release is made, change log
13sections for earlier releases are merged in.
14
15Change log sections are split into two groups: major new features (normally
16only for dot zero releases) and fixes. In addition, the entries in each group
17are ordered as follows:
18
19 VMM-related entries (most important)
20 GUI-related entries (most visible for users)
21 Device-related entries
22 VBoxManage/API/Main-related entries
23 Host-related entries
24 Guest-related entries
25 BIOS/EFI/ACPI-related entries
26
27Please do further ordering as seems appropriate by importance and visibility for
28users, e.g. audio before serial ports and generally Windows before Linux. Please
29also try to describe the user impact, not the technical details, and only use
30technical terms if no non-technical ones are clear enough.
