slib (2d2-1) unstable; urgency=low

  * New upstream version
  * Revert back to free.  Is now so.

slib (2d1-1) unstable; urgency=low

  * New upstream version.
  * Move to non-free.  FSF pointed out license doesn't allow modified
    versions to be distributed.
  * Get a complete list of copyrights that apply to the source into
    copyright file.
  * Remove setup for guile 1.3.
  * Remove postrm.  Just calling install-info (lintian)  Move install-info
    call to prerm since doc-base doesn't do install-info.

slib (2c9-3) unstable; urgency=low

  * Change info location to section "The Algorithmic Language Scheme" to
    match up with where guile puts it's files.
  * Postinst is running slibconfig now.  (Closes: #75891)

slib (2c9-2) unstable; urgency=low

  * Stop installing slibconfig (for guile).
  * In postinst if /usr/sbin/slibconnfig exists call it (Close: #75843
    #75891).

slib (2c9-1) unstable; urgency=low

  * New upstream (Closes: #74760)
  * replace string-index with strsrch:string-index in http-cgi.scm.
  * Add doc-base support (Closes: #31163)
