1-321312413124 days ago I could download SM 2.0 and other (1.-231 and 1.6), but now it's forbidden. Why? And how I can download SM 2.0?

And on this page written: SourceMod's PDB Symbol Server: https://sm.alliedmods.net/symbols/.
But it's forbidden too

SourceMod 2.0 on smdrop was actually SourceMod 1.5 thats why it got removed.
SourceMod 2.0 became 1.6 instead (or somewhat like that).
Major changes and introduction like SourcePawn2, but i dunno what exacly happend.

Devs, correct me if im wrong.

The sourcepawn2 and sourcemod-experimental repos were only vaguely relevant sometime in like 2013 or 2014. The sourcepawn2 repo was a rewrite of at least the compiler and sourcemod-experimental was a fork of SM that used it. The old snapshot pages called sourcemod-experimental builds 2.0.

No one at the time could really do anything useful with either, let alone someone now 3-4 years later. The compiler rewrite now exists in the exp/ subdirectory of the SP git repo, though it's not actively worked on. I'm sure some changes in sourcemod-experimental got moved over to the main repo trunk, but the point was just to use SP2.

Asking why the PDB server isn't readable means you probably don't know what it's for. You're not supposed to manually be looking at it in a browser.

Old SM builds are intentionally no longer available.
