+## 2026-07-07   3.16.2:
+### Enhancements
+
+* Add a `--installer-type` command line option to build only a single installer type (`sh`, `pkg`, `exe`, or `msi`), overriding `installer_type` from the configuration. (#1266)
+
+### Bug fixes
+
+* Fix `AzureSignTool` signature verification failing for installer paths that contain spaces. (#1273)
+* Improve the EXE installer path length check added in #1228 to also account for the package cache extraction path (`pkgs/<name-version-build>/`), preventing installations that were allowed to proceed from failing to extract packages when the install path was long. (#1282)
