• 23,300+ utility classes for colors, spacing, typography, layout, and more.
• Parses XML files and writes an app.tss with only the classes you use.
• Customizable through config.cjs, with arbitrary values for one-off sizes and colors.
• Icon fonts for Buttons and Labels: Font Awesome, Material Icons, Material Symbols, and Framework7-Icons in Alloy and Classic projects.
• build-fonts installs custom fonts in Alloy or Classic; TSS class definitions are generated only for Alloy.

Unreleased​

v7.17.1​

• The notification icon is now named notificationicon.png. firebase.cloudmessaging resolves that exact name, so data messages find the icon without any manifest wiring; under the old ic_stat_notify name they fell back to the opaque launcher icon and the status bar showed a white blob. Projects that wired @drawable/ic_stat_notify by hand update one meta-data line and delete the five stale files.

v7.17.0​

• --dependencies scaffolds an ESLint setup that runs. The template is eslint.config.mjs, a flat config for ESLint 9 that declares the Titanium and Alloy globals and ignores generated code. eslint-config-axway and eslint-plugin-alloy are no longer installed: neither works under ESLint 9.
• The images: section rejects unknown keys. A typo like qualty: 95 is now an error naming the offending key and the entry index, instead of silently falling back to the default.
• The generated images: block documents the 4× convention. The comments state where the output sizes come from, why there is no width key, and which formats quality actually reaches.

v7.16.2​

• Custom-font modules expose every processed family. build-fonts --module maps each TTF/OTF to the exact PostScript name Titanium expects, even when the project contains no icon CSS.
• Classic color commands avoid unrelated empty source folders. shades updates only purgetss/config.cjs, while color-module writes the CommonJS file under Resources/lib/ without initializing brand, font, image, or Alloy scaffolding.
