# Changelog All notable changes to this project will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [4.5.0] - 2026-10-06 ### VEE Port Requirements - MicroVG API 1.5 - VG Pack 1.8.3 - C Module MicroVG 8.0.3 ### Added - Add a measurement test for a glyph drawn with cubic curves in an OpenType font. - Add a measurement test comparing the TrueType and the OpenType format of the same font on curved glyphs. - Add a drawing test checking that an OpenType font whose font matrix is not the default one draws at the size its TrueType format draws. - Add a measurement test for the height of a string whose leading space is followed by a glyph drawn above the baseline. - Add a measurement test for a character that draws no ink at either end of a string. - Add a measurement test for a combining mark folded in at its own pen position. - Add a drawing test for a string whose leftmost pixel is the end point of a curve. - Add a drawing test for a letter spacing that crosses a pixel only over a long string. - Add a measurement test checking that refused drawings leave the complex layouter's heap intact. - Add letter spacing measurement and drawing tests in complex layout and on a circle, which expect the values of the simple layout. - Add drawing tests checking that a string drawn with the MicroUI or the MicroVG painter draws nothing on the column after its measured width. - Add a drawing test checking that a MicroUI string drawn into a buffered vector image sized to its measured width and height draws the same pixels as the direct drawing. ### Changed - Expect the box the glyphs draw, instead of the box the font declares, in every text measure case. - Check the MicroUI text width of a vector font against a measure that is not a whole number, which a VEE Port truncating that width now fails. - Expect a text measure to be the union of the ink of all its glyphs. - Expect a text measure to be positive or zero, and 0 when nothing is drawn. - Expect a drawn text to start on the leftmost pixel it draws. - Expect the ink box of an emoji, instead of its advance, in the emoji measurement and drawing cases. - Run `TestDrawString` in a launch of its own, outside `AllTestClasses`, since it needs a larger image heap than the batch gives. ### Removed - Remove the test class comparing the OpenType and the TrueType rendering of one glyph, `TestFontIncorrectOTFGlyphSize`. ### Fixed - Fix the empty-string measurement test, which checked the height but not the width (introduced in version 4.4.0). - Fix the character sweeps, which measured the left-overflowing character twice and never the right-overflowing one. ## [4.4.0] - 2026-09-15 ### VEE Port Requirements - MicroVG API 1.5 - VG Pack 1.8.2 - C Module MicroVG 8.0.2 ### Added - Add numeric measurement tests for text in complex layout. - Add tests asserting both layouters agree on text needing no shaping, and on the empty string. - Add a rendering test for complex-layout text drawn on a small-radius circle. - Add performance tests for complex-layout text measurement, drawing and drawing on a circle. - Add `AllTestClasses`, which runs the test classes in a single launch, for a VEE Port with enough memory to hold every test resource at once. - Add a measurement test for a glyph whose extreme point ends a curve. - Add a test that measures a complex-layout font loaded after another one was closed. - Add a test that measures a complex-layout font loaded after the SNI close function released another one. ### Changed - Shorten the first Arabic string of the complex-layout drawing test and regenerate its reference image. ### Fixed - Close the images that test classes allocated without releasing them. - Close every complex-layout font the tests open, which they used to leave open to work around a C Module defect. ## [4.3.3] -
