+* Mon Sep 28 2026 ai-importer <ai-importer@openeuler.org> - 1.0.1-4
+- Switch vendored libiio from 1.0.0 to 0.25: adi-iio 1.0.1 uses the libiio
+  0.x API (iio_buffer_cancel/destroy, single-arg iio_channel_enable/disable,
+  iio_device_create_buffer, iio_buffer_refill/first/step/push) which was
+  removed/changed in libiio 1.0, causing compilation failures in iio_buffer.cpp.
+  libiio 0.25 header (iio.h) is at source root, not include/iio/ subdirectory.
 * Mon Sep 28 2026 ai-importer <ai-importer@openeuler.org> - 1.0.1-3
 - Disable libiio network backend: it requires libavahi/libxml2/libzstd which are
   not pulled in; local backend suffices for adi-iio's iio_create_context_from_uri
