BEFORE YOU READ
It appears I had misheard information regarding the Village & Pillage update, as Village & Pillage is actually the plans for 1.15, not 1.14. I will update accordingly. I apologise for any confusion/misinformation I have caused.
I am not really sure whether Villager & Pillage is 1.15 for not and this is getting a bit confusing. Soooo for now I'm putting 1.14 and Village & Pillage update as there own lists, without mention of 1.15. When they stated some parts would release late this year and others next year, they might've meant in terms of snapshots. We'll just need to wait on official words to clear it up a little more. Thanks for your patience.
BRIEF RUNDOWN:
1.14 UPDATE NEWS:
Pandas – Pandas will spawn in jungles and are a neutral mob until aggro'd or will become friendly when given bamboo. Spawns in Bamboo forest biomes. Mention of a very rare "brown panda" was mentioned.
Bamboo & Scaffolding – Bamboo is a new plant that will spawn in the a Bamboo forest biome. Used for pandas and can be made into scaffolding. Scaffolding will be easy to manuever and remove (like the Timber mod).
Cats revamp – Cats and ocelots will now be seperate mobs. To tame a cat you will need to find a stray cat and befriend them. They can give you gifts too. There are going to be 9 cat types. 8 revealed so far, the 9th will be up to the community to decide.
BIOME VOTE – Taiga – Berry bushes, foxes, and campfires will be coming to the game first! Proposed Desert and Savannah biome revamps will come at a later time TBA.
"VILLAGE & PILLAGE" UPDATE NEWS:
Crossbows – They seem to be loaded and fired in separate actions, and can shoot arrows and fireworks. According to the official Minecon announcements page – 3 enchantments will be available – Fast Load, Multishot, and a secret third enchantment.
Revamped Biome Villages & Villagers – Villages are redesigned depending on the biome and the villagers will now have skins depending on what biome they spawn in. Trading was also confirmed to be updated. On top of biome specific textures, villagers will get unique textures based on their professions (more than the 6 basic ones we have now) and I believe they mentioned giving them different behaviours for different times of day (meeting in market areas, going to work, etc). (Thank you u/sixfootblue for the reminder and good description)
Pillagers – Illagers that will raid villages in a group weilding weapons e.g. crossbows. Definitely hostile.
Illager Beast – Beast travels alongside Pillagers to help raid, seem to be tanky, they also had a saddle on its back so could be implying that Pillagers can ride them
Sandstone walls – Not much to say but neat, huh 😀
Smooth Sandstone Stairs and Slabs – These are also being added in! Praise bonus stairs and slabs!
IDEAS FOR LATER VERSIONS MENTIONED:
Brown Mooshrooms – Was mentioned in the Q&A, new Mooshroom type – probably to represent the brown mushrooms. MAY NOT BE FOR 1.14 – rewatching the clip it seems like it was a question they agreed with and want to add it in the future.
Potential Target Block – Would emit a redstone signal with its strength depending on how accurate the shot is when hitting it.
Possibly new dimensions in the future

Please let me know if I've missed anything or have gotten something wrong. I will update the post. Also please note I've pointed out some points of interest that have no confirmed use yet.
Edit 1: Added in cats revamp, sandstone walls, and video links
Edit 2: Brown mooshrooms, crossbows and brown mooshrooms clip from stream vod
Edit 3: Added link to official "Everything we announced at Minecon" page, details on Crossbow enchantments
Edit 4: Updated Revamped Villagers to have more details
Edit 5: Corrected myself on my errors on separating 1.14 and 1.15, as I originally thought they were the same update.
Edit 6: Due to complications and information being up in the air right now, it is unsure whether Village & Pillage is actually 1.15 or not. For now I will keep them separately in lists, but won't refer to V&P as 1.15, just as V&P. Wew… this is a lot to take in.
Edit 7: Added in Smooth Sandstone Stairs and Slabs. Sorry for not adding this sooner, was busy.
