OpenXR Specification 1.1.58 (2026-03-31)
This release features several fixes and improvements to the specification as well as a number of new extensions. The most notable are the two new ratified multi-vendor extensions, XR_EXT_view_configuration_views_change and XR_EXT_interaction_profile_battery_state_display. - Specification - Change: Update the extension process document to include an alternate method of distinguishing experimental extensions during their development. (internal MR 3678) - Clarify: In XR_EXT_spatial_entity, clarify that update snapshot must not included unlisted entities.
