Version 9

9.8.0-beta.12 - 29 October 2026

Fixes

Secured documents in the browser - a document with restrictions or a password failed in Blazor WebAssembly with Could not create the encrypter information, as the browser has no MD5, and the PDF security handler needs it to make the encryption keys. The handler now uses its own MD5 on every platform, so the same documents are made in the browser, on a server and on the desktop.

9.8.0-beta.11 - 29 October 2026

Fixes

Allowing modifications no longer also allows high quality printing - with 128bit encryption, modifications (document assembly) in print-restrictions, or AllowDocumentAssembly in code, also turned on high quality printing, and cleared one of the permission bits that must always be set.
Allowing forms no longer also allows annotations - forms (AllowFormFilling) also let the reader add comments and annotations. Each allowed permission now sets only its own permission.
Passwords longer than 32 characters - a document password longer than 32 characters failed the document. Only the first 32 characters are used, as in the PDF specification, and a password with characters outside Latin-1 (e.g. Cyrillic or Chinese) is a clear error rather than a password nobody could type.

9.8.0-beta.10 - 28 October 2026

Fixes

Flex items with block content are the width of their content - an item without a width that held a block (a div), a flex column or a flex row was measured as the full width of the row. So justify-content had no space to share, and items overlapped, wrapped or ran off the page (e.g. a footer’s contact details past the page edge, or a FIG 1.1 tag broken onto 2 lines next to another flex item). Blocks inside an item are now the width of their content when it is measured, and an empty item has no width.
justify-content with a margin or a gap - the margins of the flex container itself were not taken from the space, and the gaps between the items were counted as free space, so the last item was not on the right edge, or went past it.
position: absolute with a left and a right but no width - is now stretched between them (as css), rather than being the width of its content. A max-width still limits it.
counter-increment on a display: grid or display: table element - was not counted, so every counter() after it showed the reset value (e.g. FIG 1.0 for every item).

New

box-decoration-break - a block split across pages has the full border on each part, as before (clone, the default). box-decoration-break: slice (or -webkit-box-decoration-break) cuts the border at the break instead, with no bottom border where the block continues and no top border on the continuation, as in a browser.
A warning for a counter that is not found - a counter-increment for a counter that has no counter-reset on the element or a containing element is not counted, and now adds a warning to the trace log naming the counter and the element.
The background shorthand - now sets all the background values, so any that are not given go back to their defaults (as css). background: none removes a background color or image from another rule, and a color is drawn under an image. Position and size (center / cover, 10pt 20pt / 100pt auto) are read, and scroll, fixed, border-box, padding-box and content-box are accepted and ignored. If any part cannot be read, the whole declaration is ignored, as in a browser, rather than half applied.

9.8.0-beta.9 - 28 October 2026

Fixes

A gradient that cannot be drawn no longer stops the document - a gradient that could not be read, such as a stop with 2 positions (transparent 0 10.5pt), had no colors, and the whole document failed with No boundaries were provided. The gradient is now not drawn, the background-color is shown, and a warning is added to the trace log.
transparent in a gradient - failed the document with Cannot convert colorspace None to RGB. A PDF gradient cannot be transparent, so the color is now drawn as black, with a warning in the trace log.
Line height in the font shorthand and the language of the machine - in font: 10.5pt/1.65 sans-serif the line height was read in the language of the machine or browser. Where . separates thousands (e.g. Dutch or German) 1.65 became 165, and the document could fail with Cannot fit all repeating rows. It is now always read as a css number.
Numbers in text values used in expressions - a number held as text, such as a json or field value of "1.5", was read in the language of the machine or browser when used in a calculation (), a function (`round()`, `sqrt()`, `double()`, `addDays()` and the rest) or a comparison (`model.v == 1.5`). In Dutch or German `"1.5"` became 15. It is now always read the same way as a number written in the expression. Numbers and dates written out as text, e.g., still use the language of the machine or browser.
Decimal values in transform, svg transform and orient, and <picture> sizes - were also read in the language of the machine or browser, so rotate(12.5deg) was 125 degrees in Dutch. They are now always read as css numbers.

9.8.0-beta.8 - 27 October 2026

Fixes

Gradient color stops as lengths - a stop such as var(--accent) 112pt was ignored, so linear-gradient(90deg, var(--accent) 112pt, var(--navy) 112pt) was a smooth fade across the whole width. Lengths are now a position along the gradient line, so two colors at the same position are a hard stop. A stop of rgb(...) with a position also lost its color, and is fixed.
box-shadow with a variable - a shadow with a var() in it, such as box-shadow: 9pt 9pt 0 var(--accent), was not drawn. Any part of the value can now be a variable.
Images in a flex header - an image with only a height (e.g. a logo), in a flex header or continuation-header, was missing on the first page the header was used, as its size was not known until it had been drawn once.
letter-spacing and word-spacing in em - were a size of the inherited font, rather than the font of the element, so font-size: 172pt; letter-spacing: -.04em was almost no change.
display: inline-flex (and inline-grid and inline-table) - was not recognised, so the whole display was ignored. The element now sits on the line as an inline block, with its contents laid out as a flex container, so align-items and justify-content centre its content. As a flex item it is a flex container.

Changes

A word that is longer than the line is not broken - as in a browser, a single word that is too long for a line (e.g. a large number in a narrow column) is kept whole, and overflows the line (to the left when it is right aligned). Before this it was broken at a character, onto 2 or more lines. Use overflow-wrap: break-word (or word-wrap: break-word) to break long words, for example long codes or urls in a narrow table cell. With hyphens: auto long words are still hyphenated.

9.8.0-beta.7 - 27 October 2026

Fixes

Flex items that are the width of their content - an item without a width, flex-basis or flex-grow had no width, so next to a growing item (such as flex: 1) it disappeared, or only kept its margin. These items are now measured by laying them out before the row, and the row uses the width of their content, as in a browser. Counters, ::before and ::after content, names and outlines are not changed by the measuring, and it never adds a page.
A row of only content width items is now packed at the start of the row, as in a browser, rather than split into equal columns. Use justify-content (e.g. space-between) to spread them, or flex: 1 on each item for equal columns.

9.8.0-beta.6 - 27 October 2026

New css properties

margin-block and padding-block (with -start and -end) - the top and bottom of an element, as one or two values.
inset, inset-block and inset-inline (with -start and -end) - shorthands for top, right, bottom and left, with the same one to four values as margin. auto leaves a side unset.
Accepted and ignored - cursor, pointer-events, will-change, scroll-behavior, user-select, transition and animation are read without a warning and have no effect, so a stylesheet shared with a web page can be used as it is.

Fixes

Flex row items stretch - with the default align-items: stretch, the items in a flex row are now the height of the row, so a fixed column, or a flex: 1 column, with a background or border fills the row. The height is the height of the container, or the tallest item. The container height is applied before the items are laid out, so anything inside an item that is positioned from the bottom is placed correctly. An item with its own height, or an align-self (or align-items) other than stretch, is not stretched. Before this, every item was only the height of its content.
Inline flex items (span) - the children of a flex container are blocks, so a span (or other inline element) now has its width and margins, fills its column when it grows, stacks in a column, and is centred by align-items. They stayed inline, so a width was ignored, and a column of spans ran together on one line. Absolutely positioned children are not flex items and are not changed.
Percentage border-radius - a percentage was a percentage of the container, so border-radius: 50% on a small circle drew a star shape. It is now a percentage of the width of the element (or the container, if it has no width), and, as in css, the radii are reduced so they are never larger than a side. A 50% radius on a square is a circle.
counter-increment on table rows - counters on a tr were not updated, so a counter used in the cells of the row stayed at 0. A row is counted once, and repeated header rows are not counted again. Counters on cells already worked.

Changes

overflow: hidden on text that does not wrap - text with white-space: nowrap in a block with overflow: hidden is cut back to the last whole word that fits, the same as lines that overflow vertically are removed. If the first word is wider than the box, it is cut at the last character that fits. Before this the text ran past the edge of the box. overflow: clip is still a clipping rectangle at the edge, and text-overflow: ellipsis still cuts at the character.

9.8.0-beta.5 - 26 October 2026

New css properties

word-break - break-all fills each line, breaking a word at any character with no hyphen. normal, keep-all and break-word are accepted (a word longer than a line is already broken). Inherited.
overflow-wrap and word-wrap - accepted for compatibility with existing stylesheets. They do not change the layout, as long words are always broken.
text-overflow - ellipsis, clip or a quoted string. The end of text that does not wrap (white-space: nowrap) in a block with overflow: hidden (or clip) is replaced so it fits. Inherited.

Fixes

Negative text-indent - a negative indent now hangs the first line only. The next line was staying out at the negative position, and so was any text after a <br />. Following lines now start at the edge of the content.

9.8.0-beta.4 - 26 October 2026

Fixes

visibility: collapse on table rows - a collapsed row, or a group of rows (thead, tbody, tfoot), is removed from the table with its space, as with display: none. It was treated as hidden, which kept the space. Collapse on any other element is still the same as hidden, and on a column it is hidden.
border-collapse and border-spacing are inherited - as in css, they can be set on a container (or the body) and apply to the tables inside, including nested tables. They were only read from the table itself.
box-shadow and outline on images - they were only drawn for blocks and tables. Images (inline or block) now have shadows and outlines.
cellspacing attribute on a table - supported, a number is in pixels. A css border-spacing overrides it.

9.8.0-beta.3 - 26 October 2026

New Features

text-decoration-color, text-decoration-style and text-decoration-thickness - the color, style (solid, double, dotted, dashed or wavy) and thickness of underline, overline and line-through, also accepted in the text-decoration shorthand (text-decoration: underline wavy red 2pt). See text-decoration-style.
outline, outline-color, outline-style, outline-width and outline-offset - a line around an element, outside its border, that takes up no space. See outline.
box-shadow - offset, blur, spread and color, with more than one shadow and rounded corners. inset shadows are not drawn. See box-shadow.
text-shadow - offset, blur and color, with more than one shadow. Inherited. See text-shadow.

Fixes

Inline images with a margin - an inline <img> (or other drawn component) with a margin was drawn at its width and height plus the margins, starting at the edge of the margin. It is now drawn at its own size, inside the margin, as a display: block image is. The border was already in the right place.
sortBy of plain values - sortBy(values) and sortBy(values, 'desc') sort the values themselves (such as the result of keys()), without a property name.
sortBy with duplicate values - items with the same sort value caused an error. They are now all kept, in their original order.

9.8.0-beta.2 - 26 October 2026

New Features

keys() function - the keys of a dictionary, or the names of the properties of an object or JSON object, as an array that can be counted, sorted and enumerated. See keys.
text-indent - indents the first line of a block of text. Inherited. See text-indent.
object-fit and object-position - fit a raster image into its box with contain, cover, none or scale-down, and place it with keywords, percentages or lengths. See object-fit and object-position.
border-collapse and border-spacing - collapsed table borders are drawn once between cells and with the table (the wider wins), and separate borders can have space between the cells. See border-collapse and border-spacing.
visibility - hidden content keeps its space in the layout but is not drawn. Inherited. See visibility.
box-sizing - content-box makes width and height the content only, adding the padding and border. The default (as border-box) includes the padding in the width, and is unchanged. See box-sizing.

Fixes

Quoted property names in collection functions - sortBy, sumOf, averageOf, minOf, maxOf, countOf, eachOf, selectWhere and firstWhere accept a quoted name ('price', 'owner.city') as well as .price. A quoted name was previously treated as a constant.
Properties named e, pi, true, false and null - a name directly after . or ../ is always a property, so model.e and model.pi work. A bare e or pi is still the constant.
join() accepts join(collection, separator) as well as join(separator, item, item...). The collection first order is the one documented.

Scryber.Core.Mvc 9.8.0-beta.1 (and 9.8.0-beta.2)

Package dependency fixed - Scryber.Core.Mvc 9.6.0.14-beta to 9.8.0-beta listed a dependency on Scryber.Common, which is not a package (it is included in Scryber.Core), so the package could not be restored from nuget.org. Version 9.8.0-beta.1 depends only on Scryber.Core. Use this version or later.

9.8.0-beta - 25 October 2026

New loop variables and dictionary iteration, the text-transform property, and a number of binding, parsing and font fixes.

Behaviour Changes

**over a dictionary or JSON object now iterates the entries** - for a `Dictionary<,>` (or any `IDictionary`), a Newtonsoft `JObject` or a `System.Text.Json` object, the loop runs once per entry, with `this` as the value and `@key` as the key. It used to run once with the whole object as `this`, so a template that used to bind a single object should use `` instead. The <template data-bind> element and the ForEach component still bind an object once.
**../ inside gives the outer item** - it used to return the collection being enumerated, so in a nested loop was always empty. It is a single level only; ../../ is not supported.

New Features

text-transform - none, uppercase, lowercase and capitalize. Inherited by child elements, can be set from an expression, and a capitalized word continues across inline elements. See text-transform.
@first and @last - alongside @index, in output, ``, if() and css expressions inside a loop. @last is correct for arrays, lists, dictionaries and Linq iterators. They are restored after a nested loop.
@key - the key or property name of the current entry when iterating a dictionary or object, or the index for a collection. It is set for each loop and restored when the loop ends, so nested loops see the right value before and after. See @key.
var() and calc() inside gradients - linear-gradient() and radial-gradient() colors and positions can use css variables and bound values.
background shorthand accepts gradients - background: linear-gradient(...) and radial-gradient(...) were previously not applied.
Document.ParseDocument() and ParseHtmlDocument() (and the async versions) have overloads that take ParserSettings - for a TextReader or a Stream, so the conformance mode no longer needs the longer Document.Parse() call.

Fixes

Strict mode with `` over a Linq iterator - a non-resettable enumerable (for example list.Select(...)) failed with Specified method is not supported. Arrays and lists were not affected.
Fonts:Register weight and style - the Weight and Style of a registered font are now used, rather than the weight and style declared in the font file. A light font file can be registered as weight 400.
<?paperwork ?> processing instruction in HTML5 templates - it was only recognised in XHTML templates.
Image factories registered in configuration - a handler for a custom path or type can now decode the stream supplied by a RemoteFileRegistered requestor (request.Callback(owner, request, stream)). The handler receives an empty mime type and should work out the format from the data. Set shouldCache to avoid the request being raised twice for one image.
Custom components derived from Panel - child content in the template was silently dropped; it is now kept. A parsed ComponentList declared with [PDFArray(typeof(Panel))] no longer fails with No 'Add' method ... accepting Panel.

Deprecated

HtmlFragment - the component is marked obsolete. HTML content is parsed directly into the component tree, or can be included with the object, embed and iframe elements, or data-content binding.

9.7.5 - 7 October 2026

Consistent error handling in strict and lax mode. Invalid syntax is now invalid completely, and missing data is not a syntax error. The full behaviour is in the processing instructions truth table.

Behaviour Changes

Invalid expression syntax always throws — in strict and lax mode. This now includes an expression that compiles but is incomplete when evaluated (,), a function with the wrong number of parameters, and an invalid expression inside a repeating or conditional template (,). Lax mode previously logged these and carried on, or skipped the template.
A root variable that is not set (or is null) logs a single error in both modes — e.g. `` with no model. Strict mode previously threw, and lax mode logged two warnings. The value is left unset and the document continues.
A null part way along, or at the end of, a path is silent — model.missing.value where missing or value does not exist is just null, rather than an error. `` with no object now outputs 1. .
CSS var() and calc() follow the same rules — var(model.missing.value, red) uses the default if there is no model, missing or value; without a default the property is left unset, with an error logged only if there is no model. Invalid css expressions are validated and raised when the css is parsed.
Document.CreateParserSettings() and CreateParserSettingsAsync() now default to Lax — matching Document.ParseDocument() and the render options. A parser-mode processing instruction still overrides the default.
Expressions supplied as data to eval() are still treated as any other evaluation failure (strict throws, lax logs a warning), as they are not part of the template.

New Features

int() function — a short name for integer(), alongside long(), double() and bool().

Fixes

Function documentation corrected — the reference now uses the names the engine registers: monthOf (not monthOfYear), deg, rad, isMatch, matches and swap (not degrees, radians, regexIsMatch, regexMatches and regexSwap). The examples in the expressions crib sheet that used monthofyear never evaluated, and have been corrected.

9.7.4.4 - 1 October 2026

Fixes

colspan cell content squeezed into one column — the content of a cell spanning several columns (paragraphs, text) was being laid out at the width of its starting column rather than the full spanned width. The cell’s outer box was already the correct size, but the content inside was not.
<figure> no longer forces its content to be unsplittable — a <figure> was set so it could never split across a page, which was meant to keep an image and its caption together but also applied to a long table wrapped in a figure. A table too tall to fit on one page now splits normally instead of failing with an InvalidOperationException.

9.7.4.3 - 1 October 2026

Fixes

colspan cells losing a colgroup column’s width — where a <col> column is never occupied by a single-column cell in any row (for example a three-column percentage colgroup where every row spans the middle column), its width was dropped and every colspan cell crossing it lost that width. The width is now resolved through the normal style pipeline, so percentage, em, rem, viewport units, calc() and var() all work on <col> widths.

9.7.4.2 - 10 September 2026

Fixes

Image aspect-ratio with a resolved width and height — max-width, max-height, min-width and min-height are now honoured, and the other dimension re-derived from aspect-ratio, when both dimensions were already resolved (for example an <img> sized only by its width/height attributes inside a percentage-width <figure>). Previously that combination skipped clamping and the aspect ratio entirely.
<hr> is a real box-model element — it is now a block with border-*, background-color, height, width and margin, instead of a stroked diagonal-line path. Resets such as border: none; height: 4pt; background-color: #369; render a coloured bar instead of a diagonal line, and a bare <hr> keeps its default 1pt solid black bottom border.
JSON values from a dictionary — a JsonElement or JToken stored as a value in a Dictionary<string, object> parameter is now normalized in the same way as nested JSON property access, so double() and string() work on a top-level property too.

9.7.4.1 - 8 September 2026

New Features

CSS Display Module 3 two-value display — e.g. block flex, inline flow-root, alongside the single-keyword values.
hsl() and hsla() colours — supported anywhere a colour is accepted (the CKEditor colour pickers produce them).

Fixes

display: table and grid with //`` — content generated by a helper is now wrapped correctly rather than dropped or leaving an empty cell, including a table row nested inside the repeated content keeping the table’s shared column grid.
Loose display: inline-block inside a table or grid cell is treated leniently as a block, rather than rendering blank.

9.7.4 - 4 September 2026

Fixes

Multi-threaded rendering — fixed a data race in font glyph registration (PDFFontWidths) that could corrupt the text of documents rendered concurrently, sometimes writing the wrong glyphs without an exception. Contributed by twofatmonkeys (PR #186). The Scryber.Core.OpenType dependency is updated to 9.7.4, which fixes a companion race in the glyph metric cache. Both are required for concurrent rendering to be safe.

9.7.3 - 4 September 2026

New Features

Image EXIF metadata — images now capture EXIF data (including GPS coordinates as signed decimal degrees), available in templates with the new meta(path) and meta(path, key) functions.

Fixes

Loose content inside display: table — a child that was not a table row or cell (for example an image inside a designer-authored <figure> with display: table) was silently dropped from the layout, and never registered as a PDF image resource.

9.7.2 - 27 August 2026

New Features

CSS structural pseudo-classes — :nth-child(), :nth-last-child(), :first-child, :last-child, :only-child and the -of-type equivalents, with full An+B formulas (odd, even, 2n+1, -n+3). These match across the wrappers produced by ``.
CSS !important — the declaration flag is now detected and takes priority in the cascade.

Fixes

Flex row items no longer need to be a Panel — non-container children such as bare text are wrapped so they get a block layout box.
Element immediately after `` — an element with no whitespace after the end of a loop could be dropped when it shared its parent’s tag name.
Processing instruction parser-mode is now passed down to the generated document.
Expression that fails to evaluate is logged as a warning, rather than an error (an expression that fails to compile is still an error).
Font widths — removed a shared buffer in PDFFontWidths as the first part of the multi-threading fix completed in 9.7.4.

9.7.1 - 13 August 2026

Adds fine-grained content permissions for <iframe>, replacing the old all-or-nothing style passthrough.

New Features

allow attribute on <iframe> — a ten-type content permissions policy (data-passthrough, style-passthrough, inner-style, inner-link, inner-navigation, inner-images, outer-html, inline-styles, inner-frames, inner-forms) controlling what is kept from embedded content and what passes through from the parent. See the allow attribute reference.
data-content on <iframe> now enforces allow — dynamically bound content goes through the same permission-cleaning pipeline as content loaded via src, including outer-html wrapping behaviour.
outer-html permission controls whether a full embedded <html>/<body> document is preserved as its own container or reduced to just its body content, now also supporting header/footer content from the embedded document.

Fixes

data-passthrough restored as a legacy attribute — the boolean data-passthrough="true"/"false" attribute (superseded by allow during development of this release) is back as a working, [Obsolete]-marked convenience wrapper, so existing templates keep working. It sets both data-passthrough and style-passthrough together, matching its original pre-allow behaviour. New templates should use allow to control each independently.
Expression binding regression — deep JSON/JObject property access on a missing intermediate property (e.g. deeparray[1].object.value where object doesn’t exist) had started silently returning a non-empty value instead of an empty result, an incidental regression introduced while building the iframe permissions work. Fixed.

9.7 - 6 August 2026

Significant new version with more general support for CSS and HTML5 features including major improvements in CSS flex, CSS grid, CSS table-xxx. Along with support for z-index, colgroup, and column-fill.

Breaking Changes

Image width and height attributes now only accept integer values, as intrinsic size hints. Providing a unit (pt, px, %, etc.) throws an exception. Move unit-based image sizing to style: style="width: 400pt;".

New Features

CSS aspect-ratio property sets a fixed width-to-height ratio on images and block elements. When only one CSS dimension is specified, the other is derived from the ratio.
Added <colgroup> and <col> table column elements to wire column widths, background colours, and CSS styling directly on column definitions. Also supports the span attribute to apply styling across multiple consecutive columns.
Added grid-template-areas and grid-area — define named layout regions and place items into them by name.
Added named grid lines in grid-template-columns/grid-template-rows along with reference names in grid-column and grid-row.
Added grid auto-fill and auto-fit in repeat() to fill a row with as many fixed-width tracks as will fit without specifying a count.
Added grid grid-auto-columns and grid-auto-rows to control the size of implicitly created tracks when items overflow the declared grid.
Added grid justify-content and align-content to distribute the grid along the inline and block axes when tracks are smaller than the container.
Added full support for flex-basis, flex-direction, flex-flow, flex-grow, flex-shrink so flex containers now output as expected.
Added flex align-items in column direction so flex containers now correctly support cross-axis alignment.
CSS var() and calc() in flex/grid now work inside all CSS property values.
column-fill support for reflowing content in a multi-column layout to match heights in each. Default is still auto to match existing behaviour on templates.
z-index support for positioned content, so order of rendering can be controlled.
Added FindMatch() to component that can execute a JQuery’esque search for any Components that match that query, returning a collection of results, and queries can be chained.

Fixes

SVG image min/max sizing — min-width, max-width, min-height, max-height are now honoured for SVG images, with correct aspect-ratio preservation when only one axis is constrained.
SVG images clipping — unsized SVG images (no viewBox, no declared dimensions) no longer clipped to 300×150 regardless of the <img> box size.
Page breaks — a page-break-after: always followed immediately by page-break-before: always no longer inserts a redundant blank page between sections.
Grid page overflow — continuation row gaps are stripped and height corrections propagate correctly across page breaks.
Grid row-span cell height and row-gap border rendering fixed for multi-row spanning cells.
Flex wrap — various fixes for inter-row padding/margin/border.
List overflow — fixed infinite layout loop when an <ol>/<ul> overflows with zero visible contents.
Anonymous table wrapping — anonymous <tr>/<td> insertion no longer absorbs insignificant whitespace nodes, preventing empty cells.
Font glyph table — PDFFontDefinition now outputs the correct glyph offset count in the bfrange CMap table.
Infinite pagination — fixed a case where a header or footer that itself requested a page break caused the layout engine to loop indefinitely.
