The WordPress plugin repository always starts with what is in trunk. It reads down to the “Stable Tag” label. If the stable tag is “trunk” it continues reading from trunk. This is what people who download your plugin will get.
If, however, the stable tag label is a tag (in this case, 1.0.7), it quits reading trunk and goes to that tag directory and reads from there. This is what people who download your plugin will get.
If you are adding a new tagged version, you need to add that directory to tag, and then update the stable tag in trunk. You also need to give the repository a few minutes to update. Changes are not immediate.
