Blizzard made an announcement on March 12, 2016 that they've finally come back and updated Diablo II after all this time. The new patch is labeled 1.14a and includes new hashes, a new version byte
0x0E, and of course bugfixes for the actual game.
Here's a copy of the news post:
It’s been a long time coming, but today we’re releasing 1.14a for Diablo II.
This update focuses on system glitches introduced by modern operating systems. In related news, you can finally retire those old Mac PowerPCs. Included with the update is a shiny new installer for OSX.
We’ve also begun working to improve our cheat-detection and hack-prevention capabilities. There’s still work to be done, but we’re making improvements every day.
There is still a large Diablo II community around the world, and we thank you for continuing to play and slay with us. This journey starts by making Diablo II run on modern platforms, but it does not end there. See you in Sanctuary, adventurers.
And here are the patch notes:
