1.3 update:

General:

-Added support for Last Stand content
* CS weapons and shovels can now spawn throughout the campaign

Level 1 (Freight Terminal):

-Disabled physics on some weapon spawns that unintentionally had them enabled

Level 2 (Pumping Station):

-Fixed a certain item spawn placing the item underneath a shelf in the warehouse

1.2 Update:

General:

-Updated stringtable dictionaries just in case they might cause crashing for some people
* NOTE: This issue can still persist/re-emerge if you have lots of add-ons (or several very large ones)!
-Fixed missing bracket in all mission files (eliminates console error message on game startup)
-Changed mission name from "CSPort" to "CSPortForL4D2"
*This is primarily a test for a new standard that I plan to implement on all of my campaigns: it's purpose is to prevent conflicts with other add-ons
-Updated all cubemaps

Level 1 (Freight Terminal):

-Minor performance improvements
-Added 7 new possible item spawns across the map
-Removed three detail props that never worked as intended
-Moved an item spawn in the warehouse that appeared underneath one of the shelves instead of on it


Level 2 (Oil Pumping Station):

-Partially reverted performance improvements added in the previous update that did not work as intended
*Some miscellaneous performance improvements have also been added
*However, most users probably won't experience any noteworthy FPS drops under normal conditions (unless your computer qualifies as a potato)
-Fixed leaking pipe sound
-Fixed missing texture on the warehouse roof that could be seen from the office windows
-Added 5 new possible item spawns across the map
-Fixed a small mapping error in the elevator shaft
-Removed nonfunctional detail props from this level, too

Level 3:

-Added 3 new possible item spawns
-Added an ambient sound effect to a gazebo that was missing one
-Removed some redundant light entities

1.1 Update:

General:

-Significant performance upgrades for all levels:
*All levels now have proper occlusion-based rendering support, which should improve framerate on lower-end computers
*All levels have also had some degree of performance-improved retexturing. This should slightly decrease memory usage as well as map filesize
*These optimizations are not perfect (due to Valve's original mapping methods), so your experience may vary
-Fixed floating foliage detail sprites (grass etc.)

Level 1 (Freight Terminal):

-Fixed several floating spotlight effects

Level 2 (Oil Pumping Station):

-Made health items less common
*Pills and adrenaline are now about 25% less common, first aid kits about 30%
-Marked elevator ladder with a small arrow graffiti
-Fixed several floating spotlight effects

Level 3 (Evac Finale):

-Added 9 more possible lines for Virgil
-Added an additional possible upgrade spawn point (incendiary/explosive ammo and laser sight)
