+Subject: [PATCH 1/4] fix --capath use
+
+A regression in curl 8.17.0 led to a customer CAPATH set by the application
+(or the curl command) to be ignored unless licurl was built with a default
+CAPATH.
+
+Add test cases using `--capath` on the custom pytest CA, generated with
+the help of the openssl command when available.

+Subject: [PATCH] curl: fix progress meter in parallel mode
+
+With `check_finished()` triggered by notifications now, the
+`progress_meter()` was no longer called at regular intervals.
+
+Move `progress_meter()` out of `check_finishe()` into the perform
+loop and event callbacks.

+Subject: [PATCH] wcurl: Really fix CVE-2025-11563
+
+When we pass a string to is_safe_percent_encode, it always begins with
+"%'.  But the lookup table UNSAFE_PERCENT_ENCODE does not contain "%" so
+nothing can be matched.
+
+Also update the test suite to fix the false positive.
