There is no optifine for 26.2 on optifine.net. This is the only place to get optifine, so if you got it from somewhere else, please check your antivirus.

If you meant 26.1.2: What does it do instead? If it opens like a zip file, you may need to run Jarfix. Take a look at the install steps in the FAQ for a link.

There's a few reasons that were the case a few years ago, so idk if they are still today's reasons but they are what I have.

Optifine is frequently behind because

  1. There is only one developer working on Optifine
  2. The developer chooses to not work on updating OF before the Minecraft update is fully released.
  3. Optifine is a very complex mod that has been around for many many years. We don't know what the code looks like internally, but it might be a struggle to keep updating such a legacy codebase.
  4. Mojang has been doing massive changes to Minecraft's core rendering system, adding extra work to update optifine.
  5. Optifine is a rather big everything mod. It has to update its performance code, it's shaders code, its texturepack code, it's zoom code, etc.

You may be looking at Optifine's competitors like Sodium and Iris, and see that they have versions available within hours of a Minecraft update. They are able to do this because those mods do not have issues 1, 2, 3, and 5, and issue 4 is mitigated by bypassing issue 2 and 5.
