Hello, I think the list compiled in the initial email done by *Gabriel Caruso* [1] is a good starting point.
Copied here for reference. 15+ years old: - experimental/RETURN_REF - experimetnal/RETURN_REF_PATCH - experimental/pre_new_hash_func - experimental/zts_stdc_scanners - experimental/rand_redesign - migration/EXPERIMENTAL - experimental/namespaces - migration/unlabaled-1.67.2 - experimental/ZendEngine2 - experimental/apache_hooks - experimental/apache_hooks - migration/unlabaled-1.3.2 10+ years old: - migration/unlabaled-1.29.2 - migration/INITIAL - migration/sqlite-start Not even 5 years old, but no commit: - str_size_and_int64_56_backport - native-tls - zend-signal-zts Not even 2 years old, but no commit: - microseconds Just to be clear I'm not asking to remove Version branches not historical important ones, but mostly just the ones which have no commit, or are obsolete.
