For those who haven't heart yet; there will not come a McEdit for 1.13; the team has moved on to a new editor called "amulet-editor". This project is still at first steps and no - there is no test version so far and it could need much time before it starts. See there webside for mor infos:

Where can I find old versions of MCEdit? I mean the ones for Alpha and Beta. I've seen some of the old ones can also be used to convert Classic .mine saves to newer versions. I still have some old .mine save files from 2010-2011.
I'm super excited to tell you that I've been trying to do exactly that for years now, and tonight I've finally managed to do it. So! Here's what I did:
Download the oldest available version of MCEdit (you can go through all of MCEdit's versions on GitHub here, or you can skip to the oldest one here)
Run the program (you don't even have to install it if you don't want to, just leave it in your Downloads folder)
In MCEdit, click Open World and navigate to your .mine file to open
Once you open the .mine file, you can click and drag to select areas (or click the MCEdit menu in the top left and hit Select All)
On the left side of the screen you can select Copy and then Export to save this world somewhere as a schematic
Still within MCEdit, create a new world (or load one you want to add your old .mine world to)
Once it's open, click the Import icon (along the bottom of the screen) and navigate to wherever you saved the schematic
Import the schematic, place it somewhere on your map, click Save under the MCEdit menu, and you're good to go!
Open Minecraft (this version of MCEdit exports worlds for Minecraft 1.8) and you can now play!!
I hope this goes wonderfully for you and you enjoy it as much as I have. It's only been a literal decade... Safe to say my nostalgia is really intense tonight :') Happy gaming and let me know if you have any questions!!
You can find even older versions of MCEdit here; I still use 0.1.7.1, the last stable release from CodeWarrior, the original creator (there's also a newer "dev" version which may or may not be fully functional):
Notably, even 0.1.7.1 can load worlds from versions as new as 1.12; it just has issues with editing tile entities and items, though those don't matter since I play on 1.6.4, thus I've never bothered updating MCEdit (it is also important to note that 1.8 changed the way items are saved and if newer versions of MCEdit do not account for this you must not use them to edit items, though copying e.g. chests seems to work):
