+# 📊 Enhanced Frequency Analysis 📊 #
+This a quick release adding several `frequency` enhancements for more detailed frequency analysis. The `frequency` command now includes a percentage column, calculates `other` values, and supports limiting unique counts and negative limits.
+These options provides additional context for qsv-pro and `describegpt` so their metadata inferences are more accurate and comprehensive.
+
+Previously, for a 775-row CSV file containing one column named `state` with entries for all 50 states, `frequency` only showed:
+
+```
+field,value,count
+state,NY,100
+state,NJ,70
+state,CA,60
+state,MA,55
+state,FL,45
+state,TX,43
+state,NM,40
+state,AZ,39
+state,NV,38
+state,MI,35
+```
+
+Now, there's a new `percentage` column and `other` values calculation, both of which have configurable options:
+
+```
+field, value, count, percentage
+state, NY, 100, 12.90
+state, NJ, 70, 9.03
+state, CA, 60, 7.74
+state, MA, 55, 7.10
+state, FL, 45, 5.81
+state, TX, 43, 5.55
+state, NM, 40, 5.16
+state, AZ, 39, 5.03
+state, NV, 38, 4.90
+state, MI, 35, 4.52
+state, Other (40), 250, 32.26
+```
+
+This release is also out of cycle to address a big performance regression in the `excel` command caused by unnecessary formula info retrieval for the `--error-format` option introduced in 0.126.0. This has been fixed, and the `excel` command is now back to its speedy self.
