+# 0.8.0
+
+Adds a `manual_removal` QC check, so data points that have been checked by a person and found to be bad can be
+flagged from a hand-maintained file rather than needing a metadata threshold.
+
+### New features
+
+- **Manual QC flagging**: the new `ManualRemoval` QC method flags data points listed in
+  `__assets__/manual_flagging/<network>/manual_flags.csv`. Each row gives a site, the variables affected (separated
+  by `;`) and the date range, for periods that a person has checked and found to be bad, for example during sensor
+  maintenance or a known fault. A variable of `ALL` flags every variable at that site, and an empty end date means
+  the period runs to the end of the data. Each network has its own file, and COSMOS is the only one with a list so
+  far.
+
+  This is a temporary method until a proper manual flagging process has been implemented within the FDRI system.
+
+### Documentation
+
+- `docs/operations.md` gains a "Manual flagging" section covering the file format and how the check differs from
+  the metadata-driven QC methods.
