2026-05-23New function memory_full_upPaul Eggert
* src/alloc.c (memory_full_up): New function. Replace all callers of memory_full (SIZE_MAX) with callers to this function. This simplifies callers and should make future changes easier. It also saves a whopping 296 bytes in executable size with gcc 16.1.1 20260515 (Red Hat 16.1.1-2) x86-64.
2026-04-12; * src/xwidget.c (Fmake_xwidget): Fix commentary.Eli Zaretskii
2026-04-12xwidgets: re-enable with newer webkit2gtkDirk-Jan C. Binnema
By disabling hw-acceleration we can re-enable xwidgets with newer webkit2gtk versions (Bug#80728). Newer versions were disallowed (Bug#66068) since they abort when a webkit view is created; however, they work fine as long as we disable hw-acceleration, since the off-screen windows that xwidgets uses do not support that. * configure.ac: Remove upper-bound for webkit2gtk version check. * src/xwidget.c (Fmake_xwidget): Turn off hardware-acceleration.
