Last change on this file since 97494 was 97494, checked in by vboxsync, 3 years ago

Storage/VD: Fall back to synchronous I/O even for async requests if the async I/O interface is not available. Fixes virtio-scsi failing with the host cache enabled because it will submit concurrent requests from different threads which means some of the synchronous requests get converted to asynchronous requests due to disk lock contention, ticketref:19717

25Release change log structure
26
27Each release has a matching log of changes which were made for that and
28earlier releases. Earlier releases means anything with a lower number (e.g.
295.0.18 is lower than 5.1.2) which was released before this one. The log is
30kept in the file doc/manual/user_ChangeLogImpl.xml. Anything worth mentioning,
31particularly new features and fixed bugs, with a trac bug number if possible,
32should be added to the top of the change log (that is, the section for the
33upcoming release) for the branch in which it first appears - stable or
34development - before the next release. If you back-port it to older branches
35please add an entry there too. When a new major release is made, change log
36sections for earlier releases are merged in.
37
38Change log sections are split into two groups: major new features (normally
39only for dot zero releases) and fixes. In addition, the entries in each group
40are ordered as follows:
41
42 VMM-related entries (most important)
43 GUI-related entries (most visible for users)
44 Device-related entries
45 VBoxManage/API/Main-related entries
46 Host-related entries
47 Guest-related entries
48 BIOS/EFI/ACPI-related entries
49
50Please do further ordering as seems appropriate by importance and visibility for
51users, e.g. audio before serial ports and generally Windows before Linux. Please
52also try to describe the user impact, not the technical details, and only use
53technical terms if no non-technical ones are clear enough.
54
55Rules for adding a changelog entry to make them look more uniform:
56
57 1. Begin the entry with an UPPERCASE letter, e.g. "Foo: Fixed" vs. "Foo: fixed"
58 2. Use the past form of something, e.g. "Fixed ..." vs. "Fix ..."
59 3. No dot (.) after the entry, e.g. "<para>Foo: Bar</para>" vs. "<para>Foo: Bar.</para>"
60
61 Full example:

63 <listitem>
64 <para>Foo: Fixed something really important</para>
