Pull request overview
Backports #26304 to release/v7.5 to align PowerShell’s Debian package ICU dependency handling with the .NET runtime’s “supported version range” approach, improving compatibility across ICU versions.
Changes:
- Introduce explicit ICU min/build/max version variables and document the rationale in
Get-PackageDependencies. - Generate Debian
libicuNNdependency alternatives dynamically from a version range instead of hardcoding a fixed list.
| # - ICU typically releases about twice per year, so +30 provides roughly | ||
| # 15 years of forward compatibility. | ||
| # - On some platforms, the minimum supported version may be lower | ||
| # than the build version and we know that older versions just works. |

Grammar: 'older versions just works' should be 'older versions just work'.
