Here are features 25+ that I mention at the end of the video:

* the Vector API now loads and stores vectors to and from MemorySegments (from the foreign memory API)
* lots of new methods on `Math`: `ceilDiv(int, int)`, `ceilDiv(long, int)`, `ceilDiv(long, long)`, `ceilDivExact(int, int)`, `ceilDivExact(long, long)`, `ceilMod(int, int)`, `ceilMod(long, int)`, `ceilMod(long, long)`, `divideExact(int, int)`, `divideExact(long, long)`, `floorDivExact(int, int)`, `floorDivExact(long, long)`, `unsignedMultiplyHigh(long, long)`
* new constant `Math.TAU`
* on `BigDecimal`: `TWO` (very important! :D) and
*

I'm listening while unloading the dishwasher and getting breakfast ready for the family, which is my most common time for youtube.

I watch while I sip coffee, post dinner! Thank you and Merry Christmas! 🤗

[dominicbue]

i really enjoy your videos and i'm looking forward to the next to come

[onebeartoe]

This is great! I listened to it in the shower and then watched it again while eating breakfast, ha!

[prdoyle]

Re your question - I'm usually just watching you on the screen for these.

"it's intentionally simple and explicitly NOT meant to be used in production" - i feel im gonna need to quote that a lot in my project

[BrettRyan]

I watch while in bed winding down to go to sleep. When I see something that gets me excited I spring to my laptop to try it out. The seemingly small set size is so nice :)

[dimanekr]

Thank u guys, for helping in keeping hand on a Java pulse

[ReendeR]

You got me - I listened to you while showering and shaving my beard :)

[alexandre]

😂😂😂 Happy moment during my breakfast 🎉🎉🎉, Great Nik

[Ambusher]

I watch this at work so I can say I am investing in Java
:D

[martinmuhlemann]

Most of the time I watch the videos when I wait beside the bed of the kids until they sleep or when I'm in the bed before I sleep.

[JorgetePanete]

About vectorization for cpu, and gpu calls, what defines when each one should be used? I think Intel is working on some kind of cpu-gpu abstraction

[Kroppeb]

Wait, isn't feature 24 getting removed again in Java 20?

This dude talking about JDK 19 but industry still struck in JDK 8🙄🙄😂
