+# 3.32.0 (2023-04-08)
+
+* Improve source map quality by adding column information. This fixes several
+  source map use cases, such as Jest inline snapshots, source map composition,
+  and some debugger features. ([#759]) (Emily Marigold Klassen)
+  * Unfortunately, this change comes at some performance cost. Previously, the
+    slowdown from enabling source maps was about 10%, and now it is about 30%.
+    In most cases, the more detailed source maps are probably still preferable,
+    so for configuration simplicity, there is currently no option to switch
+    back to source maps without column information. If you would like to still
+    use the faster but less accurate implementation, feel free to file an issue
+    to request a new config option, or create the source map yourself in
+    wrapper code by copying the
+    [original simple implementation](https://github.com/alangpierce/sucrase/blob/9b20ea57aa95d0926fcb560f1500f984d598aa00/src/computeSourceMap.ts).

 # 3.31.0 (2023-03-26)
