Clea F. Rees submitted an update to the
prooftrees
package.
Version: 0.9.3 2026-02-21
License: lppl1.3c
Summary description: Forest-based proof trees (symbolic logic)
Announcement text:
----------------------------------------------------------------------
prooftrees now uses the updated forest-ext (v0.3) for tagging and
memoize-ext for memoizing tagged tableaux (if memoize is loaded).
Changes should not affect the user interface unless custom tagging
was enabled, in which case some modifications may be required.
(But in this case, almost everything is done by the user and not
this package, so hopefully this should not be a problem.)
This greatly simplifies the memos since most complications
involving catcode changes can be avoided.
