alienBOB and myself have put online some trees which may be of interest to people looking for previous versions of Slackware or multilib packages.
The new trees provided by alienBOB are 'cumulative' archives of the slackware64-current and multilib trees spanning years of Slackware development - housing nearly every package since the initial releases of Slackware64 and multilib.
If you've ever needed to downgrade a Slackware package to a previous version for (because of a driver issue, feature change, etc) you will know the value of 'cumulative' trees such as this.
The trees we now have online are:
https://slackware.uk/cumulative/slackware64-current/ - A tree containing every package added to 64bit -current, going back to the first ever release of Slackware64.
https://slackware.uk/cumulative/multilib/ - alienBOB's multilib repository going back to the first releases of multilib for 13.0. Unfortunately some compat32 packages are missing from this archive, but the recent trees do include a full set of compat32 packs.
There is also a new tree for 32bit slackware-current:
https://slackware.uk/cumulative/slackware-current/ - however, this tree is brand new, so will only accrue changes as of today. Unfortunately alienBOB did not have an archive of changes to 32bit current, and my google-fu was not strong - I couldn't find one online.
If anyone has a cumulative archive of the 32bit -current tree going back however many years, please get in touch with me - if possible, I'd like to take a copy of the tree from you to put a historical archive online.
Going forward, the trees will be synced with their original counterparts after each update, so things will be kept up to date for the long term.
Hopefully most of you will never have cause to install previous versions of Slackware packages, but the trees are there for those people who know why they need older packages.
Cheers!
