2.15.0 release Enhancements: - Add a support for decompressing Zstandard-compressed YAML files. modulemd_detect_compression() function now recognizes files with "zst" file name extension and files with Zstandard magic bytes and returns MODULEMD_COMPRESSION_TYPE_ZSTD_COMPRESSION constant for them. modulemd_module_index_update_from_file() can load Zstandard-compressed YAML files now. - Remove a dependency on "file" library (libmagic). libmodulemd now implements its own detection of supported compression formats. This saves roughly 9 MB from a minimal system installation. - An XML specification for in-YUM-repository metadata is available in "xml_specs" directory. This new format aspires for replacing modulemd-v2, modulemd-defaults-v1 and modulemd-translations-v1 YAML formats. A motivation is to unify with other XML files in YUM repositories. Please note that this specification is not yet implemented. Incompatible changes: - Meson minimal version increased to 0.55. Deprecation: - Deprecate intents in modulemd-defaults specification. System intents, which parameterize a default stream and default profiles of a module, were never implemented in the package managers (e.g. DNF). Users are discouraged from using this feature. Future libmodulmed versions might deprecate and later remove parts of an API pertaining the intents. Fixes: - Fix a crash when converting a modulemd-packager object with a default profile and without a module name or stream to a module index. - Fix parsing empty profiles. Previously a profile with an empty rpms list was misparsed as a list with a single, empty package name. - A specification for modulemd-v2 format was corrected to require a "content" license subtree only if the module build contains artifacts. - Double-quote strings in scalar YAML values when they look like a number. Most of the fields in the YAML files are required to be interpreted as strings. Unaware third-party parsers could misinterpret number-like strings (e.g. 2.30) as floats (i.e. 2.3), leading to mismatching string representations. This is now prevented by quoting these values (i.e. "2.30"). - A build script now correctly asserts a requested Python version. Previously Python 3 /usr/bin/python program could be mistaken with Python 2 interpreter. - meson-0.64.0 warnings about "check" option of run_command() were fixed. - Warnings from g_str_equal() macro of glib2 about passing an unsigned char * to strcmp() were fixed.
