Miniflux version 2.1.2 introduces a new configuration parameter FILTER_ENTRY_MAX_AGE_DAYS
. One difference in behavior is that that approach will ignore new entries, while this trigger adds them marked as read.
Deprecated
Miniflux version 2.0.45
This problem has annoyed me for a while. Old entries are suddenly added to the feeds in my Miniflux instance. Sometimes as old as several years.
