v0.10.0-alpha.2

This release includes many fixes and enhancements, particularly for modules. It also starts requiring Go 1.22 or later, as Go 1.23.0 will be released very soon.

Modules

The cue help documentation for modules and inputs has been expanded, and a number of error messages when using or publishing modules are now more helpful.

A new concept guide on CUE language versions documents the language.version field in cue.mod/module.cue files.

CL 1198249 adds support for an @ignore file attribute to unconditionally ignore a file when loading packages or calculating dependencies.

CL 1198003 teaches the CUE loader to support symbolic links when loading from local directories, matching the behavior before CUE_EXPERIMENT=modules was introduced.

CL 1198143 tweaks cue mod init without an argument to create a module with the module path cue.example rather than an empty path that made the module file invalid.

Go API

CL 1198157 fixes cue/parser to accept keywords as valid selectors, aligning with the language specification.
