+Text measured and justified the way it is drawn. Content-sized text boxes
+hold the line they are sized for, justified text is justified in every font,
+and Korean documents serialize in milliseconds. All packages share the line:
+engine (crates.io `forme-pdf`), every `@formepdf/*` npm package, `formepdf`
+(PyPI), `forme-go` (tag v0.28.0), and the VS Code extension.
+
+Addresses #181, #182 and #186.
+
+### Changed: these move existing documents
+
+- **Content-sized text holds its shaped line** (#181). Intrinsic width summed
+  each character's unshaped advance while the line breakers measure shaped
+  text, so where kerning widened a word, a content-sized box (a flex item, a
+  table column) came out a fraction of a point too narrow and the word split
+  mid-way: "Mumbai" in IBM Plex Serif drew as "Mumba" / "i", as plain text and
+  as nested runs alike. Intrinsic width now uses the line breakers' own
+  measurement
+- **Text with a hard break measures as its widest line.** Styled runs summed
+  every line's width, so a two-line cell
+  (`<span>Website Design</span><br><span>…</span>`) claimed both lines laid
+  end to end. Table columns holding such cells redistribute, closer to Chrome
+- **Justified text is justified in every font** (#186). Justification reached
+  the glyph positions only when Knuth-Plass found a solution. When it fell back
+  to the greedy breaker, the stretch existed only as PDF word spacing (`Tw`),
+  which registered (Type0) fonts never apply, so those paragraphs were drawn
+  ragged. Correction: the 0.26.0 notes said justified registered-font text was
+  fixed; that held only where Knuth-Plass found a solution
+- **Justified styled runs no longer overlap** (#186), a regression in 0.26.0:
+  on a justified line, each styled run started without the stretch of the run
+  before it, so "leaders" ran into "(finance"
+- **A line ending with a forced break is not justified** (#186), as CSS
+  `text-align-last` specifies
+
+### Fixed
+
+- Font subsetting builds its glyph-to-codepoint map once instead of scanning
+  every BMP codepoint per glyph: a Korean document with 1,000 distinct
+  syllables serializes in 85 ms instead of 4.7 s, byte-identical (#182, from
+  @captyoungkyu's patch in the issue)
+
+### Internal
+
+- The README links the production-user form at formepdf.com/production
+- Intrinsic width now shapes text, so automatic table layout in a registered
+  font is slower: a 300-row table takes 268 ms instead of 231 ms

 ## Recent highlights
 
+- **0.28.0**: text measured and justified the way it is drawn. Content-sized text boxes (flex items, table columns) hold the shaped line they are sized for, so kerned words no longer split mid-word; justified text is justified in registered fonts too, styled runs no longer overlap when justified, and a line ending with a forced break is left unjustified as CSS specifies; Korean documents serialize in milliseconds instead of seconds. Addresses issues #181, #182 and #186. Some of these move existing documents; the [changelog](https://github.com/formepdf/forme/blob/main/CHANGELOG.md) lists them.
 - **0.27.0**: text that survives copy and paste. Combining marks and shaped clusters in Arabic, Hebrew, Devanagari and Latin extract as their source text in PDF.js and Poppler, while staying valid PDF/UA and PDF/A; registered emoji fonts work as fallbacks; whitespace a font cannot encode, such as the narrow space in French amounts, no longer prints "?"; and styled right-to-left text places numbers and Latin words where Chrome does. Addresses issues #170, #171 and #175, with fixes contributed by @amruthpillai. Some of these move existing documents; the [changelog](https://github.com/formepdf/forme/blob/main/CHANGELOG.md) lists them.
 - **0.26.0**: text is drawn where it is laid out. Registered fonts (including the substitutes every PDF/UA and PDF/A document embeds) keep their kerning, justification and mark placement on the page; right-to-left text reads in the right order, with the HTML `dir` attribute and CSS `direction` honoured; ragged-right lines stay inside their boxes; and tagged output stops nesting its marked content, so files are about 5% smaller and inline link text is tagged inside its link. Fixes issues #156 to #162. Several of these move existing documents; the [changelog](https://github.com/formepdf/forme/blob/main/CHANGELOG.md) lists them.
 - **0.25.0**: flex geometry corrected in four places where the engine measured items by their border box and CSS measures them by their outer box, and an item taller than a fixed-height row now overflows it equally in both directions, as Chrome does.
