What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

- **added** — Added SDL_HINT_MOUSE_DPI_SCALE_CURSORS hint with default value of "0" to prevent cursors from unexpectedly changing size
- **changed** — Replaced SDL_PROP_SURFACE_ROTATION_NUMBER with SDL_PROP_SURFACE_ROTATION_FLOAT
- **changed** — Replaced SDL_HINT_EMSCRIPTEN_FILL_DOCUMENT and related properties with SDL_WINDOW_FILL_DOCUMENT flag and SDL_SetWindowFillDocument()

This is an SDL 3.4.0 release candidate, so please [let us know](https://github.com/libsdl-org/SDL/issues) if you run into any issues with it!

In addition to bug fixes since the last release candidate, we've made the following API changes:
* Added SDL_HINT_MOUSE_DPI_SCALE_CURSORS and changed the default to "0", so cursors don't unexpectedly change size.
* SDL_PROP_SURFACE_ROTATION_NUMBER has been replaced with SDL_PROP_SURFACE_ROTATION_FLOAT
* SDL_HINT_EMSCRIPTEN_FILL_DOCUMENT and related properties have been replaced with the SDL_WINDOW_FILL_DOCUMENT flag and SDL_SetWindowFillDocument()
