NEW: • Redesigned UI for the latest macOS. — New app icon which embraces the Squircle. — Updated iconography throughout the app. • Cascadea is now a Universal Binary. • Added combination add/remove sections button to the default Style Editor toolbar, replacing the old separate buttons. • Users on the latest macOS can select from three different toolbar appearances for the Style Editor: “Unified”, “Compact”, and “Expanded”. — The toolbar style can be chosen in Preferences -> Editor. — Unified provides larger controls and a streamlined design. — Compact reduces the size of controls and the height of the toolbar. — Expanded shows a separate title bar, much like the Style Editor on previous versions of macOS. — When using the Unified or Compact toolbars, you can also optionally disable showing the window title to create more horizontal space for controls. Titles will still show on tabs when multiple styles are open. — These new toolbar options are not available on macOS Mojave or Catalina. • SF Mono is now the default Style Editor font on macOS 10.15.4 and higher. • Added support for configuring “range” and “number” UserCSS variables. — If you already have styles using these variables types installed, you may need to update these styles, or remove and reinstall them, for the variables to appear in Style Properties. • Reworked Safari extension logic to improve performance. • A new “Go to Line” menu item has been added to the Edit -> Find menu in the Style Editor (or via keyboard shortcut ⌘L). • Added keyboard shortcuts for increasing or decreasing the font size directly in the Style Editor (⌘+ and ⌘-). — To accommodate these new keyboard shortcuts, some existing keyboard shortcuts have been adjusted. • Cascadea’s toolbar popover in Safari now displays what styles are active on the current page. — Double-clicking the name of a style in this list will open the style for editing. • For UserCSS styles with a homepage set, you can now open a style’s homepage from the context menu when right-clicking/Control-clicking a style in the Style List. • The Rule Editor sheet can now be resized in both axes to better enable editing lengthy rules. • An error popover now appears in the Style List to alert you when Cascadea can’t connect to iCloud. FIXED: • Pages in Safari are no longer visibly rendered before Cascadea can inject custom styles to reduce flashing of unstyled content before your styles can be applied. — When used in conjunction with Safari 14, expect to see much less “flashing”! • Reduced occurrence of elements animating/transitioning to new colors/styles when styles are applied at page load in Safari. • Addressed a case where the user may be prompted to install styles on pages that end in .user.css or .user.styl but are not raw CSS files. • Fixed an issue where UserCSS “select” variables which use an asterisk (*) to denote their default value may not compile correctly when that value is selected. • Updated internal Ace version to 1.4.12 (was 1.3.3). • Adjusted appearance of scroll bars in the Style Editor when macOS is set to always show scroll bars to better match the system light/dark appearance. • Improved logic for preventing duplicates when merging your local style database with iCloud. • Improved extension logic to prevent injecting sections that consist solely of comments. • Fixed an issue where choosing to suppress warnings about the Safari extension being disabled or about opening read-only styles from the warnings themselves did not correctly sync this preference to iCloud. • New styles now start at version 1.0.0 rather than 1.0 by default for better interoperability with other UserCSS-compatible style managers. • Fixed a case where “select” UserCSS vars may not import correctly. • Improved matching logic for “domain” rules. • Misc. fixes and improvements.

NEW: • Added iCloud sync. — Enabled by default if you are signed into iCloud. — Sync includes your style database and preferences. — iCloud sync can be enabled or disabled in Preferences. — If a style is deleted due to an iCloud sync operation, it can be recovered from Preferences as long as Cascadea has not been quit since the style was deleted. • Added support for styles written using the Stylus preprocessor language. — When creating a style, there is a new option to choose between writing in CSS or Stylus. — Added new option to the Metadata panel in the Style Editor to select a preprocessor to use for the style. — Viewing documents with the .user.styl extension in Safari will now prompt to open them in Cascadea. • When exporting styles that include variables, @var statements will now be included in the UserCSS metadata. • Added keyboard shortcut for quickly enabling/disabling all styles in Safari (Ctrl+D). • Added additional Style Editor themes: — Tomorrow — Solar Light — Plastic — Chromium — Monokai — Solar Dark — Hacker — Nord Dark • Added new preference for the font used in the Style Editor, including: — Menlo (default) — Courier — Monaco — Fira Code — Cascadia Code — SF Mono (requires macOS 10.15.4 or newer) FIXED: • Clarified alert that appears when attempting to close styles with unsaved changes. • Added “Cancel” button to alert that appears when closing unsaved styles. • Improved UserCSS parsing to better prevent sections consisting of stray comments. • Reorganized “File” menu and consolidated “Import From” options in new submenu. • Fixed an issue where the Style List’s size and position were not correctly restored when relaunching Cascadea. • Fixed a rare crash that could occur when importing .sdb files from Preferences. • Fixed a rare crash that could occur while changing Style Editor preferences. • Misc. fixes and improvements. And to all of you using Cascadea — thank you sincerely. I’m glad I could make something you find useful, whether you use it for theming sites, improving legibility, removing unwanted content, quickly developing and testing CSS, or whatever your use case may be. It’s a scary time in the world, and I hope you all stay safe and take care of yourselves.

Happy holidays to all who celebrate! This one's just a few quick fixes: FIXED: • Fixed an issue causing some styles with one section and no UserCSS metadata to crash Cascadea or not import correctly. • Fixed an issue where section names would not appear correctly in the section list after deleting a section.

FIXED: • Fixed a regression in 1.4.3 where some styles’ @-moz-document rules were not parsed correctly due to newlines.

FIXED: • Fixed slow performance/instability when toggling the “Enable Styles” checkbox from Cascadea’s toolbar popover in Safari. • Fixed an issue splitting sections when importing UserCSS styles (aka, the "SO Dark" fix).

FIXED: • Fixed an issue parsing UserCSS variable values that include CSS at-rules. • Fixed an issue when importing styles with @-moz-document rules where sections may not be split correctly. • Context menu options are no longer accessible for styles in the process of updating to prevent conflicting changes. • Improved reliability of “URL” rule-matching. NOTE: For users on Safari 12.1 or 12.1.1, there is a known issue that causes custom styles to intermittently fail to apply.

NOTE: For users on Safari 12.1 or 12.1.1, there is a known issue that causes custom styles to intermittently fail to apply. This is an issue on Safari's end and is expected to be addressed in a future update to Safari. Safari Technology Preview 82 and newer are unaffected. FIXED: • Fixed a crash that occur when importing or updating styles with UserCSS variables. • Fixed an issue where regular expression rules may not import correctly. • Improved regular expression matching when applying styles. • Fixed an issue when importing UserCSS styles with “color” variables whose default color values were in shorthand hex format (#000 etc.) where the wrong color would be parsed. After installing Cascadea 1.4.1, it is recommended that you perform an update on any UserCSS-format styles that may be affected by these issues, so that Cascadea can reimport the style and correct any problems.

Both @var (UserCSS) and @advanced (xStyle) formats are supported. Support for creating variables for your own custom styles is planned for a future release. In the meantime, you can manually create a custom style with variables by importing a UserCSS-compliant .user.css file or using the @-moz-document import option.

NEW: • You can now make styles take effect based on your macOS appearance settings. Use the Style Properties window to configure a style to only appear in Light mode, Dark mode, or both. Styles will even change seamlessly if you toggle between appearances! (NOTE: This feature requires Safari 12.1 and macOS Mojave 10.14.4 or newer.) • The Style Editor now allows you to specify names for individual sections of a style, to help you organize your sections. You can specify a custom name for a section in the Rule Editor. • EXPERIMENTAL*: Styles that use UserCSS variables with the “uso” or “default” preprocessors will now render correctly using their default values. • The “File” menu has a new option to import styles in @-moz-document format by manually entering the style’s CSS (useful for copy-pasting existing styles, for instance). • Enabled hardened runtime.
