	+ shared github actions, contributed by zmughal

v1.23.17 Tue, 18 Jan 2022 21:26:32 +0100 moocow
	+ merged changes for PDL 2.066+ from mohawk2

	+ updated copyright notices in PODs

v1.23.16 Thu, 29 Apr 2021 08:06:04 +0200 moocow
	+ fixed $PDL::VERSION checks in Config.PL to reflect reality
	  - integer-type downcasting behavior actually changed in PDL-2.037 with commit #f892aeb4ae on PDL/Basic/Ufunc/ufunc.pd
	  - should fix new cpantesters failures, e.g. http://www.cpantesters.org/cpan/report/1fc08e78-a7e3-11eb-aa01-337c1f24ea8f
	+ added missing "resources" level to META_MERGE section in Makefile.PL

v1.23.11 Mon, 27 Aug 2018 14:35:47 +0200 moocow
