There are enough changes before #438 merge, so I made a release to stabilize it.

IMPORTANT

1. There is a accent color-related breaking change of v103 version or higher.
   This is because Mozilla has completely removed the -moz-accent-color/-moz-accent-color-foreground property. mozilla/gecko-dev@4c5f201
   Unlike selector issues, backward compatibility cannot be guaranteed.
   Users with v102 or lower versions must use userChrome.compatibility.accent_color to true.
2. This version has icon related changes.
   If the icon directory is not copied, mac global menu related icons may not appear.

IMPORTANT

⚠️ You must copy user.js file before the theme works.

The option system depends on user configuration, and nothing applies without settings.
Also, real-time changes are difficult for technical limitations and require restarts.

Since it is a big change, if you are using custom css, back up and proceed.

🚨 Currently A fatal problem has been found in Windows. #368
Please use v5.0.2

Changed

Option System

As a first anniversary update 🎉 , an option system is introduced. #351

Everything can be configured with 100+ options and changes to a unopinionated theme.

Now the difference in distribution is just a difference in the default option configuration.
The main options are in Wiki:Options, and all other options are available in user.js.

All features from the existing wiki and the features that many users have requested are included as an option.
A case in point

• Blue accenct color at darkmode
• Megabar tweak
• Tabs on Bottom

Customize

To enhance customization, we changed the folder structure and updated the installation script.

When updating to script:

• If there are any changes: Run git stash and git stash pop before and after git pull.
• If there are user-overrides.js, userChrome-overrides.css, and userContent-overrides.css files, proceed with override

Developement

The Pure CSS file has been changed to SCSS. #234
Therefore, it becomes more structured, and the compatibility response has become easier.

Developer documents have been added to facilitate development, and discussions have been activated.
At the time of release, we decided to specify the name of the new country.

Others

• Photon like panel icon: #308
  If you want to use an before icon version, use the userChrome.icon.panel_sparse option.
