		`+ The fontconfig package is updated to the version 2.13 which contains the following features and bug fixes:`
		`+`
		`+ * config file description support`
		`+ * allow sharing caches under the bind-mounted dirs`
		`+ * improve footprint on creating caches`
		`+ * variable fonts support`

		`+ == Glibc collation update and sync with CLDR`
		`+`
		+ The collation data in glibc is extremely out of date, most locales base their collation rules on an iso14651_t1_common file which has not been updated for probably more than 15 years. Therefore, all characters added in later Unicode versions are missing and not sorted at all which causes bugs like [Bug 1336308 - Infinite (∞) and empty set (∅) are treated as if they were the same character by sort and uniq]. This change is about updating that iso146541_t1_common file to the latest available version from ISO which is from 2016 and up-to-date with Unicode 9.0.0. Because additions and changes in the syntax of the new iso146541_t1_common file, updating that file requires changing the collation rules of almost all locales. Because all these collation rules have to be touched anyway, this is a good opportunity to fix bugs in the collation ruies and sync them with the collation rules in CLDR.
