Timeline​

As always, software takes as long as it takes.
However, our current planned timeline is:

• An alpha release is available today: htmx@4.0.0-alpha1
• A 4.0.0 release should be available in early-to-mid 2026
• 4.0 will be marked latest in early-2027ish

You can track our progress (and see quite a bit of dust flying around) in the four branch on github and at:
