Release Notes

EmbarkStudios/cargo-about (EmbarkStudios/cargo-about)

v0.6.6

Compare Source

Added

• PR#268 resolved #​267 by adding a unicode-ident workaround to compensate for the LICENSE-UNICODE file more closely matching the Unicode-3.0 SPDX identifier rather than the expected Unicode-DFS-2016 one.

v0.6.5

Compare Source

Added

• PR#261 resolved #​246 by adding an --offline (as well as --locked and --frozen) option to the generate command.
• PR#266 resolved #​230 by adding a --target option to generate, allowing one to specify one or more targets to filter the dependency graph by, overriding the targets configuration option.

Changed

• PR#262 resolved #​258 by using LTO for release builds, slightly decreasing binary sizes.

Fixed

• PR#263 resolved #​238 by adding the native-certs feature to use the native certificate store. This feature is not enabled by default as it is only required for corporate environments that man in the middle network traffic.
• PR#265 resolved #​198 by detecting if the parent process is powershell and exiting with an error if cargo-about's output is being redirected instead of using the -o option, as powershell is terrible and doesn't use utf-8 encoding by default.
• PR#266 resolved #​222 by adding some additional documentation on https://clearlydefined.io.

cargo-about は結局ビルド時に executable があればいい話なので、それがビルドされる時の MSRV に引きずられるのはちょっとおかしい気はする
