Reinforced glass is gone, as it didn't represent anything that exists in real life. Glass with wires in it is weaker than regular glass and does not belong in ultratech labs, it's a fire safety thing that was abandoned in the 1960s when safety glass was invented. All instances of reinforced glass and/or wired glass have been replaced with laminated glass. Laminated glass, AKA tempered glass, is what windshields and modern glass doors are made out of. It is tough, but not as tough as ballistic glass.

Tempered glass sheets can now be acquired by deconstructing laminated glass walls and doors. You can also get them from uninstalling windshields.

Reinforced windshields are now made of tempered glass (like a normal windshield) reinforced with steel brackets and slats, similar to how reinforced solar panels work. The recipe for a reinforced tempered glass sheet is autolearned.

Glass walls and doors in labs are now mostly laminated, meaning they're kind of difficult to break. This may help keep lab critters a bit more contained.

The teamster at the refugee center has been scooted a few tiles over into the far corner. This should keep him safer from the back bay monsters, though he is by no means immune to getting pulled into the melee and killed.

Backported a fix from DDA that allows monsters to properly go up stairs, provided those stairs actually line up on the map. Their pathfinding and line of sight still aren't great about this, but they'll now sometimes chase you up out of basements, so beware!

Fixed some bugs related to dropping items off of ledges. Previously, this was waaaay too destructive. It's still not perfect but should now seem a lot more reasonable.

@False Ritche submitted a ton of fixes to the Russian translation.

@UB-13 submitted an update to acid bombs which should allow them to be made with a wider variety of glassware.

@AtaxisNine submitted new tiles for the slag hulk, frigate fly, writhing root, veiled butterfly, and glowstalk.

Added a fix for MoM where the pyrokinetic aura was showing invalid tiles. It now looks like fire.

Fixed a rare issue where acid attacks which destroyed worn sided items (such as wristwatches) could cause a crash.

Modernized the elbow pads recipe. Elbow and knee pads now both require a book, one rank of tailoring, and are made from spandex and plastic.
