| <blockquote> |
| This file contains all the changes in documentation in the package <code>com.google.inject.servlet</code> as colored differences. |
| Deletions are shown <strike>like this</strike>, and |
| additions are shown <span style="background: #FFFF00">like this</span>. |
| </blockquote> |
| <blockquote> |
| If no deletions or additions are shown in an entry, the HTML tags will be what has changed. The <i>new</i> HTML tags are shown in the differences. |
| If no documentation existed, and then some was added in a later version, this change is noted in the appropriate class pages of differences, but the change is not shown on this page. Only changes in existing text are shown here. |
| Similarly, documentation which was inherited from another class or interface is not shown here. |
| </blockquote> |
| <blockquote> |
| Note that an HTML error in the new documentation may cause the display of other documentation changes to be presented incorrectly. For instance, failure to close a <code> tag will cause all subsequent paragraphs to be displayed differently. |
