i find this really confusing, i started my survival world around minecraft 1.10, and i explored tons of biomes already (jungle included), and the new 1.12 which bring parrot to the game just released, but since my world generated on 1.10, i cant find any parrot in the jungle i explored, and its really frustating if i need to start over with 1.12 from scratch. any solution ?
I also am pretty sure that parrots will spawn in already explored jungles.
My current world was originally created in 1.8, and has survived just fine. I've opted to delete some chunks in mcedit from time to time, although that was mostly just to keep the world file small, as backups were starting to get rather unwieldy.
However, I do create new testing worlds for new major releases, but I do so during the snapshot phase. I never just load my old world up in a new version until I have tested it thoroughly (easy, just make a copy of the world folder, open the copy in 1.12, and test all of your builds, biomes, whatever is important to you, until you are satisfied). Usually something breaks, like AFK fish farms (every bloody time, I swear.. ), but what testing does is let you find out what is broken, without having to guess later on when it broke, and panic to fix it when the other players on the server want to know why their community gold farm no longer works. I'm of course talking about multiplayer, but on singleplayer I would at least make a backup before loading my world into the new version, so I can still load up the old one in the old version (thanks to the launcher improvements, that's a lot easier to do).

I create new worlds for every version, mostly because I like playing with mods and choose different mods each version. Like, I played with Mo Creatures back in 1.6.4, the pre-made FTB pack "Infinity" for 1.7.10, and Pokecube and Botania for 1.10.2. Once mods get a decent foothold in 1.12 I'll be picking out a new set, and that means a new world.
I still play on a world I created in 1.5.1, and not only that, I still play in 1.6.4, the last version with the same world generation (1.6 only added horses and new loot to chests, which does not count). Actually, I don't just play that world in 1.6.4, I've never updated to any newer version, even when using my own mods (which, IMO, makes the point of versions rather moot when mods can add anything and even completely change the game; I consider 1.7+ to be unplayable without mods to fix the changes they made to the underground, with no customization added in 1.8 or even as of 1.12, a real shame for a game where mining/caving is a big part of the game, and since no newer features really interest me that much I may as well just play an older version).
However, I have made a new world for every version of my mods, each of which has had entirely different world generation (the earliest versions only changed the underground but that would still cause undesirable discontinuities in caves, which is how I explore the world. Later versions also changed the depth of the ground, which would cause the mother of all chunk walls (64-128 blocks high) if you simply upgraded an older world; my most recent mods also change and add biomes, with the layout being different with each version. Even adding one new biome is enough to completely change the placements of all biomes unless it is added separately from other biomes or as a sub-biome).
Also, you are unlikely to find parrots in existing jungles - while they technically can respawn for the most part passive mobs never respawn due to their very low mob cap and lack of despawning (you have to kill nearly every single animal, down to 10 or less, within the spawn chunks as well as loaded chunks around the jungle; normally many times this number will spawn during world generation, which ignores the cap. Also, ocelots (the exception to passive mob spawning) count towards the passive mob cap but are on the hostile mob spawn list so they ignore the passive mob cap and can easily fill it (in jungles where I've explored everything underground I've seen the entity count rise to 300-400 due to all the ocelots around. Fortunately, they otherwise have a low chance of spawning, especially when hostile mobs can spawn, and despawn after 2 minutes if more than 32 blocks from a player. Note that they do not immediately despawn when more than 128 blocks away).
My current world was started in 1.5, and one of my rules was to roughly only explore in any 2 out of 4 directions of a main base, thus leaving unexplored areas close to my current bases. This has worked quite well, although I now have an underground Nether minecart system which links all of my bases together (about 12000 overworld blocks apart from the first base to the last), and eventually you do end up exploring other areas in later releases. But if you move bases, you will always have new areas to generate to the latest versions ...
Another thing you could do if you know your way around the Minecraft file system and don't consider it cheating, is if you had an existing jungle area say, you could delete the relevant MCA files from the region folder and then revisit the area which would generate new jungles according to the latest MC version you are playing. Of course, any construction you had in that area would be deleted, but it is an option.
I updated from my 1.6 world when it got corrupted in newer versions. Same for my 1.7 world. I still have my 1.8 world that has been through 1.9, 1.10, 1.11 and now 1.12. I also started a new world in 1.10.2 because my 1.8 world needed some fixes for the newer versions, and I wanted to try new features before fixing my older world.
The 1.8 world needed some modifications to things I had built due to changes in the game, such as item elevators and mob heights, which broke some of my farms. I modified the item elevator in my guardian farm for 1.9, then it broke again in 1.10, which is when I decided to start a new world. I created a separate folder for my 1.8 world and modified the launcher settings to use that. Eventually I figured out how to update my builds for the newer versions and copied my 1.8 world into the main save folder.
So I am currently playing my 1.8 world and my 1.10.2 world in version 1.12, but I haven't gone searching for parrots yet. And I still have a separate game folder for v1.8.9 with older world saves. I even created a separate 1.11.2 folder, just in case (but so far I haven't had any problems).
No point for me, most of my worlds are a few years old or even older. I've just updated to 1.12 safetly and transfered the survival worlds I want to play back in:
1point9point5World - Created in very late Beta in that specific 1.9.5 snapshot before release. Yes, I still wasn't very good at naming worlds back then.
AllBases - Also created in the same time era as above.
Amplified Extreme Survival Island Challenge - Created in 1.7.9 or thereabouts.
Ravine Residence - 1.7.4/1.7.5 or thereabouts.
World2 (Main World) - Alpha 1.2.0
Those are just the ones I'm playing there are a few past 1.8, like my survival mansion home (Ashford), the unamed base 2016 home etc. I tend to stick to worlds.
Like Minecraft forums or interested in my world? Try My message board, it's better moderated because I run it directly and have run Internet message boards for 21+ years! Better software and I have much more control to keep the content more up to date. Free to join, 13 years+.
I haven't played singleplayer (aside from design testing) since I started playing on a server. The server I now run has been around since 1.8, and we will 'not' refresh unless there is no other option. With that policy, our players are more willing to invest more effort into large-scale and/or highly detailed builds as opposed to random structures splattered about in haste.
No, but you do want to do it every so often. Here's a tip, make the world border around 8000 blocks when you make a new world in all dimensions. When an update comes and it has new structures, you add 8000 blocks to the world border and you have many previously unloaded chunks to explore for the new structure or even biomes...
The times you really want to make a new world is when your world gets corrupted or when it gets major lag.
I typically keep my main Survival world separate from the snapshots, with the exception of when I played in my 1.9 world, when I was first adjusting to 1.9 features. It was a massive combat update, so it only made sense I changed to adjust as necessary.

Come to think of it, I mainly play fighting-based games.
I know this is an OLD post but just in case someone stumbles unpon this looking for the same answer...
Each time the world updates the biomes typically change without re-generating the already generated biomes. For example, an already generated desert biome in 1.10 and you update the version to 1.12 the already generated desert biome will still be there but your F3 menu will show the biome changed(if it changed) to another biome lets say snowy mega taiga and the desert will get snow and such. When you generate new chunks is when the new biomes will be generated for the biome of that version this is also how chunk errors are created, new and old biomes of different versions.
For example, an already generated desert biome in 1.10 and you update the version to 1.12 the already generated desert biome will still be there but your F3 menu will show the biome changed(if it changed) to another biome lets say snowy mega taiga and the desert will get snow and such.
This no longer happens as of 1.2 because the game saves biomes with chunks, so existing chunks will be completely unaffected (aside from any new biome-specific mobs that can naturally spawn):
Biomes are saved per X,Z column, rather than being calculated on the fly, which means they can be altered by tools; this is very useful for map makers. It also prevents bugs where features don't match the biome after changing the terrain algorithm. (Also known as "Biome Shifting")
Also, worlds created as far back as 1.7 are still nearly identical to the latest version - the only biome-related changes have been either some minor differences in "M" biomes and the addition of new oceans and bamboo forest as a part of jungles (more minor features, like structures and the locations of trees and ores, did change significantly in 1.13 but the worst that would happen is finding half a village, temple, etc; trees and such are only important if you are trying to use an e.g. Survival island seed with one tree, which may no longer exist, or a seed that gives the exact locations of diamond veins (which IMO is like using x-ray):
Most of the issues since 1.7 have to do with the fact that with only one exception new structures and biome-related features that only naturally generate can only generate in new chunks (the exception being ocean monuments, which can even generate in non-ocean biomes in worlds created before 1.7 because the game uses the current biome generator, not saved data, to determine if they can generate. Some things can be generated in old chunks by the player, such as beehives on player-grown trees, but those don't count since they aren't tied to the biome).
Otherwise, modded worlds are much harder to update due to changes in the mods even if they are updated to a later version; I do not provide any backwards compatibility with newer versions of my own mods even though they are all on the same version (TMCW 1, 2, 3, 4, and especially the next version (5) are all incompatible in some way besides just changes to biome layout; TMCWv5 is even fundamentally incompatible with vanilla due to various vanilla block IDs and entity NBT data being changed, though vanilla did successfully load a world, albeit with a lot of errors in the game output).
Strange. When i o something on an old update and then there is another update, the updates will apply to my old world but it says I should backup it just in case it crashes
Strange. When i o something on an old update and then there is another update, the updates will apply to my old world but it says I should backup it just in case it crashes
Backups are always smart to make, and I make one every update whenever it's time for one. Though, I've never experienced any issues, and I've made some big leaps (most recently I hopped straight from 1.12 to 1.15 just about two weeks ago).
I only have one world which was started in 1.5, and I leave areas unexplored for reasons such as 1.13 or upcoming 1.16, exercising the same principles that Mr_N_Derman denoted (most chunks west of spawn still haven't been generated). If I want the new ocean content, or the new villages (but I can just make those), I need to travel to new chunks - same with Nether biomes. But that's part of the fun for me - new features never dominate my particular goals or source of fun in this game. They're more like novel adventures. Before 1.12, I had been playing on 1.8 before making the jump. Never bothered on 1.9-1.11 because it wasn't in my interest at the time. Likewise, I don't plan on updating to 1.16 immediately.

One major reason to make a backup when updating is in case you don't like the update and want to go back to the older version.
Taking a world back to an earlier version than it was last played in almost never ends well, even if it was only opened in the newer version for a moment. The earlier version finds a bunch of blocks it doesn't recognize, decides the chunks are corrupted and regenerates almost everything.
i find this really confusing, i started my survival world around minecraft 1.10, and i explored tons of biomes already (jungle included), and the new 1.12 which bring parrot to the game just released, but since my world generated on 1.10, i cant find any parrot in the jungle i explored, and its really frustating if i need to start over with 1.12 from scratch. any solution ?
I create new worlds every update because I rarely 'finish' my worlds by getting to the End anyway. Grinding for Blazes and Endermen is just too boring. Enderdragon has also become very hard to fight. Hopefully 1.16 fixes the first problem, Endermen now get their own dedicated biome in the Nether for hunting and are common enough in soul sand valleys which I believe have Nether Fortresses.
There's no real 'finish' anyway to Minecraft, there are infinite things to do and The End isn't really my main goal anyway, it's getting all advancements that I want (minus the How Did We Get Here one because that's just ridiculous).

Haha, but that advancement is the real challenge of the game right there... probably more difficult than what Minecraft wants you to believe is the endgame. In any case, I don't see myself hitting that one anytime soon either. I feel like it's just one of those elective achievements that really serves no purpose but can be fun to try and get.

They should spawn in old jungles too but they are rarer than in snapshots.
And no, I don't create a new world every single update. It would be waste of time.
I also am pretty sure that parrots will spawn in already explored jungles.

There's no real 'finish' anyway to Minecraft, there are infinite things to do and The End isn't really my main goal anyway, it's getting all advancements that I want (minus the How Did We Get Here one because that's just ridiculous).
Haha, but that advancement is the real challenge of the game right there... probably more difficult than what Minecraft wants you to believe is the endgame. In any case, I don't see myself hitting that one anytime soon either. I feel like it's just one of those elective achievements that really serves no purpose but can be fun to try and get.
LP series? Not my style! Video series? Closer, but not quite. Survival journal, maybe? That's better. Now in Season 4 of the Legends of Quintropolis Journal (<< click to view)!! World download and more can be found there.
