+Subject: [PATCH] Change default build type to "minsize"
+
+People (and distros) have been building ksh from this project using the
+default "debug" build type since we switched from Nmake to Meson. That
+results in a ksh program whose performance is far from optimal. So change
+the default build type. If a debugging enabled binary is needed, such as
+in a CI environment, it must be requested explicitly.
+
+Related #1449
+
+(cherry picked from commit db54d369002a0e942d695838986af6bf8962d763)

+ ## Notable fixes and improvements
+ 
++- The default build type is now "minsize" since that dramatically improves the
++  performance of ksh. You can still request a debug build via `meson
++  --buildtype=debug` (issue #1449).
+ - Fix `history` command behavior when the *~/.sh_history* file has
+   specific content (issue #1432).
