"•Support for numerical flags in DECORATE deprecated. You must now always type in the full name of the flag." ----- ?
Are you using numerical flags? Why on earth? Obfuscation? What if you need somebody to help with bugfixing? They'll spend half their time doing maths and looking up constants that may not even be documented outside zdoom.pk3. You're talking about action-function flag parameters, right; not actor flags (missile, ismonster, shootable...)?
• Support for numerical flags in actor definitions added with support for numbers that span multiple integers
• Support for named flags in actor definitions disabled until we can integrate the two modes seamlessly
Seriously: if you want a quick way to specify a particular (long) flag combo, I recommend using a constant.
