user_ChangeLogImpl.xml@ 74865

Last change on this file since 74865 was 73276, checked in by vboxsync, 6 years ago
doc/manual: Big build system overhaul, because the use of entities and catalogs eliminates the need to have placeholders in XML which previously needed separate preprocessing. Many cleanups, including replacing almost all pattern rules (since their dependencies had to be too generous) and using defines instead. Also integrated many cleanups for the user manual text (which needs careful review, couldn't check yet if it uses any additional tags which some of our XSLT would ignore).
Property svn:eol-style set to `native` Property svn:keywords set to `Id Revision`

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 -->
