v0.3.0

Changed

• Each SVG image is one Form XObject: an <img>, an inline <svg>, a CSS image and an <image> inside an
  SVG. Its /BBox is the viewport, and the page paints it with Do under the matrix that places it, so a
  PDF reader such as PDFBox or PyMuPDF finds each diagram with its size and position. WeasyPrint drew the
  operators straight into the page. The form is no transparency group: it renders as before. The same
  image drawn again at the same size, on the pages or within one group, reuses its form. The
  form_xobject argument of install() turns it off.
• An SVG background or list marker is clipped at its viewport, as in Chromium: content past it showed.
  An inline <svg> with overflow: visible still shows its overflow, and its form box grows to let it through.

Fixed

• SVG text in the generic monospace family alone takes 13px as its medium size, as in Chromium and Firefox:
  MathJax writes accented letters as <text font-family="monospace"> with no size, and they came out 1.23
  times too large. A size from a keyword reads the monospace table of Chromium (large is 16px), and a size
  relative to one (2em, 50%, smaller) scales by 13/16 where the family turns monospace and back where
  it leaves. A family list (monospace, serif) and an absolute length keep their size.
• A tagged PDF (pdf/ua-1, pdf/a-2a) of an SVG with a <foreignObject> renders: WeasyPrint failed on
  the tags of its HTML, which belong to no box of the page. The Figure of the image marks the whole SVG.
• A hole in a blurred shape keeps its size: it grew by one sample on each side, so the ring of the lens in
  the OpenStreetMap logo came out thinner and its shadow lighter than in Chromium.
• The shapes of a theme-aware draw.io export are white, as in Chromium, not black. weasysvg reads the CSS of
  an SVG as Chromium does when it prints: @supports blocks apply when their condition holds, custom
  properties and var() substitute, also in presentation attributes, and light-dark() takes its light
  color. A value that var() makes invalid is unset, and an invalid color declaration or attribute is
  ignored, so the attribute or the parent value applies. WeasyPrint painted each of these black. The css
  argument of install() turns it off.

Removed

• Python 3.10, which reaches its end of life in October 2026. Pillow 13.0.0 requires Python 3.11, and it
  fixes the vulnerabilities that Dependabot reports for Pillow 12.3.0 in the lock file.
• PyPy. No known user runs weasysvg on it, and its CI job took five minutes, the longest of all.
