# F104Mapper Changelog
## v1.1.1 (2026-03-24)
– **Fix:** Date filter now has a “Date Source” option: filter by Record Date/Time Stamp (when received) or Date/Time Code (from the form) — accommodates operators who resend forms without updating the datecode
– **Fix:** Loaded Reports list now sorts by received date so recently received records appear at the top regardless of form datecode
– **Fix:** Datecodes decoded without a year context (file-loaded records) no longer produce future dates — a December datecode loaded in March now correctly resolves to the prior December
– **Fix:** Database query now orders by received time descending so that when duplicate records share the same UID, the most recently received record is kept
– **Fix:** Grid-square duplicate resolution now keeps the record with the latest received date rather than the latest form datecode
## v1.1.0 (2026-03-23)
– Alert (CSA char 3) and Sitrep (CSA char 2) indicators displayed in Report
Detail with JS8Spotter Expect request instructions (E? F!304 / E? F!305)
