It's all good.  It's a cool feature tho.  I think it was a bug at one point and they just decided it add it to the game.

It doesn't matter if its day or night.  If you look an endermen in the eyes, it will provoke it.  This is just how endermen have always worked.  Tested it in 1.9 and they do it and all versions preceding it will do it as well.

As far as i know this has always been in the game.  I've always aimed at endermen's legs to make sure they don't teleport away, since as far as i can remember there being endermen.  I don't think this is a bug, but a useful feature that you can use to your advantage.

EDIT:  Tested this in versions all the way back to 1.9.  This feature has always been in the game.  Endermen won't teleport if you hit them in the legs.  Just how it is.

/gamerule spectatorsGenerateChunks true 

This value is set to false by default for whatever reason.  I recommend going to level.dat with NBTExplorer and permanently setting this value to true.

Already known by everyone.  Mojang needs to fix this.  Duplicates MC-149178

I find it entertaining when people don't read the patch notes.  That's supposed to happen.  A quick google search would have saved you the embarrassment.

Duplicate  of MC-149178.  This is a known issue with 1.14.

Creepers always have been able to do that as far as i know.  You could have combined this with your previous report, although unnecessary because this isn't a bug.  The shields may be though. 

This is because there is a bug where when you disenchant an item, it keeps an NBT tag when its supposed to remove it, therefore causing the disenchanted book to not be able to stack with books that have never been enchanted.  There is already an open bug report MC-148476 that shows this.

Crash reports?

I noticed this as well in my worlds.  Just thought it was my mind fooling with me but turns out after some testing this is an issue.  I haven't tried it on any other version but I've only started having shield issues after updating to 1.14.  I don't know if this is intentional to try to nerf shields or if it's just a bug.

This isn't a bug, but more related to MC-149178  This probably is happening because chunk loading in 1.14 is quite broken.  Either that or your PC can't load chunks fast enough, causing you to walk into un-rendered chunks.  This happens with every version of Minecraft, you're probably just noticing it now because of how slow 1.14 chunks load.

Lighting has always been an issue with this update.  Sometimes i have random chunks that just turn dark after reconnection as well.  Doesn't matter if i update the chunk either, stays pitch black.

Come on man.  Just do a quick google search before you start complaining on the bug page that something isn't working.  Blast furnaces ARE craftable.  You just used the wrong stone.

Every version of the game has had this.  Isn't really a bug.

This isn't a bug but more of a recommendation.

If both portals have already loaded chunks on both sides of the portal (Nether and Overworld) then this is a bug.  But mobs can't load new chunks so if the overworld chunks aren't already loaded by the player, mobs will be unable to go through the portal.

Can confirm this happens if you turn off the elytra check.  When elytra check is turned off, flying too fast can cause the same crash.

Don't think this is a bug.  There just isn't a texture in the model for the inside wall of the trap door.  Any resource pack you use will still have it and personally, i think it looks fine.

Try looking on the wiki before you post a bug report.  Blast furnaces are only meant for ores, nothing else will smelt in them.  It's an intended game mechanic.
