SLAPP Change Log

  • 2.1 (12/28/24) Minor revisions. First “release” version.
    • As a housekeeping matter, if you installed the evaluation version 1.x on PC, all your updates go into the initial directory, C:\Program Files\SLAPP1.00a. Now might be a good time to uninstall and then install again from scratch — then the new install and any updates will go to a generic Symbolic Logic APPlication directory — without the misleading version number in the folder name. This issue has no functional significance, and does not arise on Mac — which already uses the generic folder name in the Applications folder.
  • 2.0 (12/23/24) Possible “release” version. Miscellaneous bug fixes: PC printer problem resolved. Vertical tree size-down repair.
  • ————————————–start version 2—————————————————
  • 1.5 (12/18/24) In addition to miscellaneous bug fixes, vertical tree work area sizes set automatically; “fleeting popup” color changed to distinguish warning from success messages.
  • 1.4 (12/13/34) File associations work on Mac. Repairs to horizontal tree layout. Also repairs an embarrassing problem with the updater where I switched pointers between x64 and ARM64 binaries. If you have v1.3, update by downloading again from the webpage.
  • 1.3 (12/8/24). Many bug fixes. Check for updates — automatically on weekly interval, and from help menu. File associations — SLAPP icons, clicking an icon opens program (if not already open), and opens the file in SLAPP (but there is a Mac bug so that files won’t automatically open). Size counters improved — esp. in “free form” exercise where counters did not work at all.
  • ————————- start simplified version numbering above ———————————-
  • 1.02α build 1 (11/21/24). Annotation fields for vertical and horizontal trees are updated to have the same edit functionality as formula fields. If you are using downloaded exercises and/or assignments, for this (and a few bugs) YOU MUST DOWNLOAD EXERCISES AND ASSIGNMENTS AGAIN. Exercises with annotation fields that were worked in v1.01 will fail to open correctly in v1.02.
  • 1.01α build 3 (11/15/24). Repairs to previous “fixes” for horizontal tree width, and for editing derivation justifications.
  • 1.01α build 2 (11/14/24). (i) Bug fixes for editing derivation justifications; this required rearranging top edit controls. (ii) Alternate path to keyboard diagram and keyboard shortcuts through help menu.
  • 1.01α build 1 (11/9/24). This is the initial evaluation version.
