Use .tar.xz instead of .zip internally in the file format to allow larger projects
What do you mean by “some computers upload as .7zip”…? No support, some computers might not be able to compress the project because some computers upload as .7zip.
The Scratch 2.0 file format uses ZIP for compression.
Flash almost definitely doesn't get the operating system to [de]compress .zip or .tar.xz, and if Flash does have facilities for .zip or .tar.xz it'll be implemented consistently on any platform. (Afaik Scratch currently implements ZIP by itself.)
You can install xz and tar Semi-support since Windows computers can't unpack these and that would make block hacking harder.

What if their parents won't let them install anything on their computer?You can install xz and tar Semi-support since Windows computers can't unpack these and that would make block hacking harder.
Also, I have a new, major reason why it shouldn't be added to Scratch 2. It will break phosphorus.

They shouldn't be using the computer then. Usually you are allowed to install anything, and if not, then it's not the right moment to hack JSON either. (for example in school or for little kids)

Support, Linux (or that penguin thing) supports tar.xz files, but on windows we can install it!

Then they should allow to download a program like 7-zip, assuming that only the admin will see how he types the password.Unless you're using a shared computer where you aren't an admin or you have parental controls/family safety enabledWhat if their parents won't let them install anything on their computer?What if their parents won't let them install anything on their computer?You can install xz and tar Semi-support since Windows computers can't unpack these and that would make block hacking harder.

7-zip comes default with windows.

It doesn't. If your Windows came with 7-Zip, then it was modified.Then they should allow to download a program like 7-zip, assuming that only the admin will see how he types the password.

Mine did… (and I'm sure it wasn't modified). All the school computers have 7-zip, and I seriously doubt they would've bothered installing it since it is barely ever used. Though I found that using 7-zip manager you can access any file on the computer, even the ones that the teachers don't let you access

Anyway, I'm sure that 7-zip is default installed…

School computers in my class come with a lot of bloatware that are programs and fonts. These include Scratch and Audacity, Copper Black, etc… . One of my mum's computers have none of these, and it doesn't include 7-zip. Both are Windows XP. There is no 7-zip in Windows 8 computer either.

Schools usually install a bunch of stuff. My school comps have 7zip but my home doesn't.

Actually, this would be a valid suggestion unlike what I told you before. I looked into the way Scratch serves and uploads assets (SVGs in particular) and the JSONs (turns out each sprite gets their own .json), and they are transferred uncompressed, despite Flash having built-in support for compression/decompression. Now I'm guessing that they are also stored uncompressed, unlike what I thought earlier. Unless the ST has a good reason to store and transfer the assets without compression, I'd be all for adding compression to assets.Well, why not store assets compressed with xz compression… snip
BTW I'd edit the OP but I'm a new scratcher

Bump. Not sure how this will turn out because of the entirely new version of Scratch though.
I'm giving you people a buffet of yummy-yummy-in-your-tummy fresh new topics to discuss straight down your face, now just eat them!!
