ChangelogEvery release,
Every release,
in one place.
New features and fixes, newest first.
v0.15.0
LatestOctober 1, 2026- NewSupports WordPress 7.1.
- ImprovedWidth, height, minimum height and spacer height offer your theme's dimension presets next to custom values.
- ImprovedUnit-less values in older content are read as pixels and tidied up the next time you edit the block.
- FixedThe height controls no longer trigger the WordPress 7 deprecation notice in the editor.
- FixedResponsive controls work reliably on typography-only blocks and on third-party blocks that get their settings from the server.
For developers
- Third-party blocks can be registered from PHP alone through fluidblocks_settings_defaults; the fluidblocks.blockSupports JS filter remains as an override.
- Removed the fluidblocks_supported_blocks filter, which never did anything; fluidblocks_settings_defaults is the one way to register a block.
v0.14.0
October 1, 2026- NewGrid minimum column width: as many columns as fit, at least a given width, per breakpoint.
- NewLetter spacing and text transform join the typography controls, each with its own value per breakpoint.
- NewCopy a block's responsive settings and paste them onto any other block that supports them.
- FixedJustification on a Buttons block that still uses its default layout aligns the children instead of spreading them apart.
- FixedColumn widths set per breakpoint now apply on phones, so multi-column layouts on small screens work.
For developers
- Extensions can allow custom keys for copy and paste through the fluidblocks.pasteableAttributeKeys JS filter.
v0.13.0
July 25, 2026- FixedFocused buttons and cards on the settings screen keep their rounded corners.
v0.12.0
July 24, 2026- NewFluid typography: font size and line height take a minimum, preferred and maximum value and scale smoothly between them.
- NewSupports WordPress 7.0.
- ImprovedNew FluidBlocks brand mark on the settings screen.
- FixedOpening the responsive popover no longer logs a warning in the browser console.
For developers
- Breaking: PHP hooks move from rcfb_* to fluidblocks_* and constants from RCFB_* to FLUIDBLOCKS_*; signatures are unchanged and no aliases are kept.
v0.11.0
May 31, 2026- NewFlex wrap per breakpoint for Row and Stack layouts, so a row of items can wrap on small screens.
- NewAspect ratio for the Image block, per breakpoint.
- NewThe popover reopens on the breakpoint you used last, until you reload the editor.
- ImprovedPadding, margin and block spacing sliders show the inherited value and say which breakpoint it comes from.
- ImprovedThe popover stays open while you pick spacing presets and closes when you select another block.
- FixedGrid spacing set to None or Default behaves correctly, and centered blocks stay centered in the editor preview.
v0.10.0
May 28, 2026- ImprovedBehind-the-scenes improvements.
Before 0.10
betaFebruary – May 2026- NewVisibility, spacing, sizes, layout and typography for 12 core blocks on four customizable breakpoints, with a mobile-first cascade.
- NewEvery control shows where an inherited value comes from, including values set in the block's own sidebar.
- NewBorders per breakpoint: width, style and color for each side, radius for each corner.
- NewHidden blocks stay editable in the editor, and "Omit from published content" removes a block from the page entirely.
- ImprovedOn supported blocks, FluidBlocks replaces WordPress 7.0's own per-device visibility, so there is one control instead of two.
For developers
- Developer API: PHP and JS filters to register blocks, change breakpoints and adjust the generated CSS.
