Update Release.mako

fix incorrect setting of disabled/disarmed flags when cheating

 Deprecations are a mechanism in FSO where a certain feature or aspect of the engine has changed or is no longer supported. Since this would normally break existing mods we have the mod table feature "[tt]$Target Version:[/tt]" with which a mod can specify what version of FSO it was developed with. The features listed above will be removed or changed when the target version of a mod is at least the version released in this post.

John Fernandez	456ee79ab4	Update Release.mako	2023-10-26 23:43:06 -04:00
Goober5000	5238f65d7c	fix incorrect setting of disabled/disarmed flags when cheating Normally the disabled/disarmed flags are only set if the destroyed subsystem is actually an engine or turret. This should be done for cheats as well, otherwise, for example, destroying any subsystem on a non-engined ship will cause it to become disabled.	2023-10-26 23:43:06 -04:00
Goober5000	47cd2a06a6	fix a crash in the apply-loadout-to-wing routine If a wing has fewer than four ships, clicking the apply-to-all button will cause a vector subscript out of range error. This fixes it.	2023-10-26 23:43:06 -04:00
Goober5000	9ac617dd1a	fix change-soundtrack after <No Music> The fix in #5578 assumed that a previously playing soundtrack would properly set the timestamp, but if no soundtrack was previously played at all, this wouldn't happen. So if we deliberately don't play a soundtrack, be sure to set the timestamp as if `event_music_do_frame()` had been called. Fixes #5705.	2023-10-26 23:43:06 -04:00
wookieejedi	365ec2a14d	Fix glare shining through cockpits in freelook (#5690 ) Fixes #3098. The `shipfx_eye_in_shadow` function did a collision check for cockpits, bit did not previously take into account of the viewpoint had a non-forward orientation (ie the player was using free look). This PR sets the collide check to take that into account with a 1 line fix. Tested with multiple FotG cockpits and fixes the issue.	2023-10-26 23:43:05 -04:00
John Fernandez	1373a42719	Fix workflow by adding reference branch	2023-10-26 23:43:05 -04:00
