Shaarly declares compatibility with "erusev/parsedown": "^1.6", yet it testsuite fails with the latest php-parsedown 1.8.0 recently uploaded to unstable. Tagging this bug as upstream, since the error suggests an actual incompatibility. In the mean time, since the testsuite (debci) is failing with php-parsedown 1.8.0, and prevents its migration to testing. Regards, taffit
