From 7c2575f1c879dd3c3ab963c0b247511d8c83f881 Mon Sep 17 00:00:00 2001 From: Phil Thompson Date: Fri, 7 Aug 2026 14:53:45 +0100 Subject: [PATCH] Support for multi-arch stable ABI filenames Python v3.15 added support for architecture-specific tags in the names of extension modules that use the stable ABI. SIP will generate these tags if they are supported. This also fixes a regression in SIP v6.16.0.
