Dear Tumbleweed hackers and packagers, It is about time that openSUSE:Factory aka Tumbleweed moves its suse_version definition up again. There were quite some build hacks in place that were explicitly pinned on 1330, as the idea was to be able to get rid of them by the time we move the version. As this is dragging on for too long though, we changed the hacks to also apply on Tumbleweed with a newer suse_version and all those tweaks are now in place. Which means we can move forward. The new suse_version will be 1550 - starting with December 1st 2017 What's the rationale behind 1550: * SLE15 / Leap 15 are using 1500 (for their entire lifecycle). * Tumbleweed is supposed to be 'ahead of the game', so we plant it between SLe/Leap15 and SLE/Leap16 (don't ask about timeframes for those, nobody knows) While packaging, you should never reference version 1550 though. your thing are compatible to suse_version >= 1500 (meaning all Leap 15.x versions) OR, if something comes into play on newer .x levels, you'd do: %if %{suse_version} > 1500 || %{sle_version} >= 150100 # Feature is available since Leap 15.1 BuildRequires: new-dep %endif This will indicate that starting with 15.1 things are present, and for TW as well. If you don't know yet about the Leap version it might become available, simply skip the sle_version check (but keep the check for suse_version > 1500) The change of suse_version has no visible impact to the end user, this is merely of interest to developers/packagers.
