We have two Confluence user macros to mark deprecated or newly added features in the documentation wiki: {since} and {deprecated}. Both aren't optimal (we can still style them if we see the need) and don't work within tables or similar structures (or maybe the versions without any parameters do, we haven't tried). See also the list of user macros.
The since macro
Examples:
| No Format |
|---|
{since}This got added in 5.2{since} |
| | Since |
|---|
| This got added in 5.2 |
|
| |
| No Format |
|---|
{since:since=5.2}This got added in 5.2{since} And this was always there. |
| | Since |
|---|
| | This got added in 5.2 |
And this was always there. |
| No Format |
|---|
{since:since=5.2}{since} |
| |
