3 ======================================================

5 Description
6 ===========
7
8 Flash messages are now styled by using the native CSS classes of Twitter Bootstrap. The changed classes are:
9
10 * "typo3-message message-notice" => "alert alert-notice"
11 * "typo3-message message-information" => "alert alert-info"
12 * "typo3-message message-ok" => "alert alert-success"
13 * "typo3-message message-warning" => "alert alert-warning"
14 * "typo3-message message-error" => "alert alert-danger"
15
16 Impact
17 ======
18
19 Extensions which use the old classes like "typo3-message message-information" rely on deprecated CSS classes
20 which might lead to non styled output.
21
22 Affected installations
23 ======================
24
25 Any installation that uses the HTML of flash messages without calling the API.
26
27 Migration
28 =========

30 Change the used CSS classes to the new ones.
