+One to four dot-separated integers |
+identifying the version of this extension. |
+A couple of rules apply to the integers: |
+they must be between 0 and 65535, inclusive, |
+and non-zero integers can't start with 0. |
+For example, 99999 and 032 are both invalid. |
+</p> |
+ |
+<p> |
+Here are some examples of valid versions: |
+</p> |
+ |
+<ul> |
+ <li> <code>"version": "1"</code> </li> |
+ <li> <code>"version": "1.0"</code> </li> |
+ <li> <code>"version": "2.10.2"</code> </li> |
+ <li> <code>"version": "3.1.2.4567"</code> </li> |
+</ul> |
+ |
+<p> |
+The autoupdate system compares versions |
+to determine whether an installed extension |
+needs to be updated. |
+If the published extension has a newer version string |
+than the installed extension, |
+then the extension is automatically updated. |
+</p> |
+ |
+<p> |
+The comparison starts with the leftmost integers. |
+If those integers are equal, |
+the integers to the right are compared, |
+and so on. |
+For example, 1.2.0 is a newer version than 1.1.9.9999. |
+</p> |
+ |
+<p> |
+A missing integer is equal to zero. |
+For example, 1.1.9.9999 is newer than 1.1. |
