#7746 05a1f0d - fix: fail the build when emitted output imports an undeclared package (@okisdev)

aui-build kept package imports external without checking them against the manifest, so emitted JavaScript or declarations could import a package a consumer cannot resolve. A build now allows only the package's own name, its declared dependencies, peers and optional dependencies (with a @types/* package standing in for the module it types), its imports map and node builtins. tsdown's deps.onlyImport covers import statements; a pass over the finished declarations covers the two shapes it does not visit, an inline import("pkg").Type and a /// <reference types="pkg" /> directive.

Test helpers, testUtils modules and benches under src are no longer build entries. They were unreachable through every exports map and carried vitest and ink-testing-library imports into published output.

#7846 b758f0c - fix: let a new SyntaxHighlighter, CodeHeader or componentsByLanguage entry reach settled code blocks (@okisdev)

a code block that streamdown had already rendered kept the previous highlighter or header when components.SyntaxHighlighter, components.CodeHeader or an entry of componentsByLanguage changed without new text, because streamdown's root memo ignores components and never re-renders the block. the code adapter now reads its components from a context that the primitive provides above streamdown, so the change reaches every mounted code block in place; the block, its siblings and the rest of the message keep their DOM and state, and a streamed token still re-renders nothing that has settled.

#7651 f36e945 - fix: keep settled code blocks from re-rendering when streamdown re-renders their block (@okisdev)

a custom SyntaxHighlighter ran again for every settled code block on each streamed token when any components entry was an inline function, and for every code block once an animated message completed; components reading useStreamdownPreProps re-rendered the same way. PreOverride now keeps its context value while the parsed pre props are equal by value, the code adapter compares the hast node by value, and an inline componentsByLanguage map keeps its identity while its entries are unchanged. a code block whose fence metadata changes while its code stays the same now hands the new node to CodeHeader and SyntaxHighlighter instead of the previous one.

#6807 9d218b3 - fix: keep a fenced display body inside the list item or blockquote it was written in (@okisdev)

giving the $$ markers their own lines put them at the root column, which ends the container the math was written inside: an equation in a list item rendered as a sibling of the list. the markers now carry the prefix of the line the match opened on and the body is aligned to it, and that line is read from the original text so a code span earlier on it cannot truncate it.
#6807 9d218b3 - perf: parse once per token with defer on (@okisdev)

the deferred path rendered the previous text at normal priority and the new text in the deferred pass, and react-markdown parses the whole accumulated text on every render, so a token cost two full parses. the renderer is memoized, which turns the urgent pass into a bail-out because that text was parsed on the previous commit. a caller's inline remarkPlugins array no longer defeats the memo.

#6885 f38aea4 - fix: preserve text escapes and custom handler changes in earlier paragraphs without completing or deleting their unfinished Markdown. (@ephraimduncan)

Incomplete Markdown repair stays in the final block. Earlier blocks receive numeric-range escapes, comparison-operator escapes, and custom handlers. Custom handlers receive the earlier text and final block as separate strings.

RemendConfig gains singleTilde and comparisonOperators, so the two escapes that now reach settled text can be turned off without disabling incomplete-Markdown repair.

Patch Changes#

#4408 b6016d1 - feat: export math-delimiter preprocess helpers for the markdown text primitives (@okisdev)

adds normalizeMathDelimiters, rewriteLatexBracketDelimiters, rewriteCustomMathTags, and escapeCurrencyDollars so you can pass them to the preprocess prop instead of copy-pasting a regex blob. they rewrite the $...$ / [...] brackets and [/math] / [/inline] tags that models emit to the $...$ / $$...$$ form remark-math parses, and escape $5-style currency so single-dollar math doesn't eat it.
#4418 2a03d96 - perf: repair only the trailing block of streaming markdown instead of the whole message (@okisdev)

StreamdownTextPrimitive let Streamdown run remend (incomplete-markdown repair) over the entire accumulated message on every streaming flush, which grows with the message. It now repairs only the last top-level block (the only place a dangling opener can be, since inline constructs cannot cross a blank line and blocks are split after repair), which is render-equivalent but bounds the heavier remend repair to the tail instead of running it over the whole message each flush. tailBoundedRemend and findRemendWindowStart are exported so you can apply the same windowing yourself. Custom remend options are honored, repair falls back to the full message when a custom parseMarkdownIntoBlocksFn is supplied, and parseIncompleteMarkdown={false} still disables repair entirely.

0.3.3#

Patch Changes#

#4348 5ca6558 - feat: opt-in defer prop on the markdown text primitives (@okisdev)

StreamdownTextPrimitive and MarkdownTextPrimitive accept a defer flag that routes the streamed text through useDeferredValue, so re-parsing the growing message runs at a lower priority and typing/scrolling stay responsive while a long message streams in. intermediate streaming states may be skipped under load; the final text always renders. default off; the shadcn kit's markdown-text turns it on.
#4357 fb1a7d3 - feat: smooth prop on StreamdownTextPrimitive (@okisdev)

opt-in typewriter reveal via the now-public useSmooth, accepting boolean | SmoothOptions. the pipeline runs preprocess, then smooth, then the existing defer deferral, and data-status/isAnimating derive from the smooth status so the caret keeps blinking and the copy/download controls stay disabled until the reveal catches up. default off; streamdown's block memoization bounds the per-frame cost to linear string scans plus the tail block parse. the @assistant-ui/react peer floor moves to the release that ships SmoothOptions.

#6885 f38aea4 - fix: preserve text escapes and custom handler changes in earlier paragraphs without completing or deleting their unfinished Markdown. (@ephraimduncan)

Incomplete Markdown repair stays in the final block. Earlier blocks receive numeric-range escapes, comparison-operator escapes, and custom handlers. Custom handlers receive the earlier text and final block as separate strings.

RemendConfig gains singleTilde and comparisonOperators, so the two escapes that now reach settled text can be turned off without disabling incomplete-Markdown repair.

#6305 e96d3de - chore: update dependencies (@okisdev)
#6449 e818d4a - refactor: single-source the code-fence contract on a react-markdown subpath. the CodeHeader/SyntaxHighlighter prop types, the by-language override entry, and the language-class parser now live in @assistant-ui/react-markdown/code-fence; react-streamdown re-exports the types from there instead of keeping structurally compatible copies. @types/hast moves to dependencies in both packages so the published declarations reference hast by name instead of a broken store-relative path.

Patch Changes#

#4408 b6016d1 - feat: export math-delimiter preprocess helpers for the markdown text primitives (@okisdev)

adds normalizeMathDelimiters, rewriteLatexBracketDelimiters, rewriteCustomMathTags, and escapeCurrencyDollars so you can pass them to the preprocess prop instead of copy-pasting a regex blob. they rewrite the $...$ / [...] brackets and [/math] / [/inline] tags that models emit to the $...$ / $$...$$ form remark-math parses, and escape $5-style currency so single-dollar math doesn't eat it.
#4418 2a03d96 - perf: repair only the trailing block of streaming markdown instead of the whole message (@okisdev)

StreamdownTextPrimitive let Streamdown run remend (incomplete-markdown repair) over the entire accumulated message on every streaming flush, which grows with the message. It now repairs only the last top-level block (the only place a dangling opener can be, since inline constructs cannot cross a blank line and blocks are split after repair), which is render-equivalent but bounds the heavier remend repair to the tail instead of running it over the whole message each flush. tailBoundedRemend and findRemendWindowStart are exported so you can apply the same windowing yourself. Custom remend options are honored, repair falls back to the full message when a custom parseMarkdownIntoBlocksFn is supplied, and parseIncompleteMarkdown={false} still disables repair entirely.

0.3.3#

Patch Changes#

#4348 5ca6558 - feat: opt-in defer prop on the markdown text primitives (@okisdev)

StreamdownTextPrimitive and MarkdownTextPrimitive accept a defer flag that routes the streamed text through useDeferredValue, so re-parsing the growing message runs at a lower priority and typing/scrolling stay responsive while a long message streams in. intermediate streaming states may be skipped under load; the final text always renders. default off; the shadcn kit's markdown-text turns it on.
#4357 fb1a7d3 - feat: smooth prop on StreamdownTextPrimitive (@okisdev)

opt-in typewriter reveal via the now-public useSmooth, accepting boolean | SmoothOptions. the pipeline runs preprocess, then smooth, then the existing defer deferral, and data-status/isAnimating derive from the smooth status so the caret keeps blinking and the copy/download controls stay disabled until the reveal catches up. default off; streamdown's block memoization bounds the per-frame cost to linear string scans plus the tail block parse. the @assistant-ui/react peer floor moves to the release that ships SmoothOptions.
