From 064b5144f868c9359082cdeb39ac23a76a68728b Mon Sep 17 00:00:00 2001 From: "R. Timothy Edwards" Date: Wed, 5 Aug 2026 09:04:54 -0400 Subject: [PATCH] Updated the documentation for the "property" command to include the new "plane" property type (which apparently was not previously documented when implemented, an oversight), and also (added by request) to add a reminder that the "MASKHINTS" property only works in conjunction with corresponding "mask-hints" records in the tech file. --- VERSION | 2 +- doc/html/property.html | 22 +++++++++++++++++++--- 2 files changed, 20 insertions(+), 4 deletions(-) diff --git a/VERSION b/VERSION index 10ef81d4..ba80bf4a 100644 --- a/VERSION +++ b/VERSION @@ -1 +1 @@ -8.3.679 +8.3.680 diff --git a/doc/html/property.html b/doc/html/property.html index c2721314..1d32ec87 100644 --- a/doc/html/property.html +++ b/doc/html/property.html @@ -31,7 +31,7 @@ Attach a "property" (string key and value pair) to the edit cell
