+## [1.0.5] - 2026-05-27
+
+### Fixed
+
+* Paint the background once and only when necessary to do so (#54).
+For example, it's not necessary or desirable to paint the
+background when printing.
+Another consequence of this fix is that it's possible now to
+render an image with a transparent background, for example in
+Frescobaldi's copy-to-image dialog.
+* Optimize the cache size to avoid unnecessary re-rendering (#56)
+* Optimize PDF rendering to save memory (#58)
+* Fix a memory leak caused by uncollected QPdfDocument garbage (#52)
