 <p>General:</p>
 
 <ul>

 <p>Fixes:</p>
 
 <ul>
-  <li>Fix MacVim not reporting its version number correctly. <a href="https://github.com/macvim-dev/macvim/issues/1011">#1011</a></li>
-  <li>Fix mvim:// protocol handler not handling line number. <a href="https://github.com/macvim-dev/macvim/issues/1020">#1020</a></li>
-  <li>Fix opening MacVim from the Dock not setting UTF-8 in locale. <a href="https://github.com/macvim-dev/macvim/issues/1033">#1033</a></li>
