1 <h1 id="version">Manifest - Version</h1>
4 One to four dot-separated integers
5 identifying the version of this extension.
6 A couple of rules apply to the integers:
7 they must be between 0 and 65535, inclusive,
8 and non-zero integers can't start with 0.
9 For example, 99999 and 032 are both invalid.
13 Here are some examples of valid versions:
17 <li> <code>"version": "1"</code> </li>
18 <li> <code>"version": "1.0"</code> </li>
19 <li> <code>"version": "2.10.2"</code> </li>
20 <li> <code>"version": "3.1.2.4567"</code> </li>
24 The autoupdate system compares versions
25 to determine whether an installed extension
27 If the published extension has a newer version string
28 than the installed extension,
29 then the extension is automatically updated.
33 The comparison starts with the leftmost integers.
34 If those integers are equal,
35 the integers to the right are compared,
37 For example, 1.2.0 is a newer version than 1.1.9.9999.
41 A missing integer is equal to zero.
42 For example, 1.1.9.9999 is newer than 1.1.
