+.NET 10 is the LTS baseline. `global.json` asks for SDK `10.0.100` with
+`rollForward: latestMajor` and no prereleases, so the newest installed SDK
+builds. The target list depends on that SDK: 11 or later builds `net10.0` and
+`net11.0`, SDK 10 alone builds `net10.0` only. The published package must carry
+both, so CI installs SDKs 10.0.x and 11.0.x explicitly and checks the package
+for both `tools/` folders. Do not switch the workflow back to
+`global-json-file`: setup-dotnet installs nothing from a `latestMajor`
+global.json.
+
 Tests must pass before you commit. They use a fake HTTP handler and never touch
 the network. Do not add a test that needs credentials. New behaviour ships with
 a test.

+## [1.5.0]
+
+### Changed
+
+- The package now targets both `net10.0` and `net11.0`. `RollForward` stays
+  `Major`, so a machine with only a newer runtime still runs it. bbx already ran
+  on .NET 11 through roll-forward, so this is for consistency, not a fix.
+- .NET 10 is the LTS baseline for building. `global.json` asks for SDK
+  `10.0.100` with `rollForward: latestMajor` and `allowPrerelease: false`, so
+  the newest installed release SDK builds. SDK 11 or later builds both targets;
+  SDK 10 alone builds `net10.0` only. CI installs SDKs 10.0.x and 11.0.x and
+  fails if the package is missing either target.
