The interesting thing is, many of these features were already included in version 3.201 which is not listed on the website anymore.

It seems like version 3.203 is just a minor security update, but they merged it into one update and are just listing all changes at once.

If you remember my previous article here, you’ll know that with 3.201 they released a major update that bumps OpenWrt up to 19.07.7.

The funny thing is, OpenWrt released 19.07.8 just four days after this update (Aug 7th) fixing some of the same issues. GL.iNet was actually faster to fix things than upstream, it seems?

You can update to version 3.203 by logging in to the admin panel and clicking on upgrade on the left, or by doing a manual upgrade:

  • Update through web Admin Panel: gl-ar750s-3.203-0701.tar SHA256: 8dfe7535a8818939342e8bed87e17edd1cd411a4583c95c6f00e51c92937c8aa
  • Update through Uboot: gl-ar750s-3.203-0701.img SHA256: 1b56b10ca7282994aef5eef2a0412b9c0b8cd2741368789ddb0383fef1d257e6

I’m really glad that GL.iNet is still providing updates. This increases my trust in them.
