3.7.5 => 3.8.3 introduces breaking change(and shouldn't)

[rmainwork]

TypeScript Version: 3.8.3

Search Terms:

1. Option 'noEmit' cannot be specified with option 'incremental'.
2. typescript incremental noEmit
3. tsc noEmit incremental

Code

{
  "incremental": true
}

tsc --noEmit

Expected behavior:

The typescript project should compile successfully (it does under 3.7.5) since 3.7.5 to 3.8.3 is not a semver breaking change the two should be backwards compatible, but aren't. https://semver.org/spec/v2.0.0.html#summary

Actual behavior:

tsconfig.json:15:5 - error TS5053: Option 'noEmit' cannot be specified with option 'incremental'.

15     "incremental": true,
       ~~~~~~~~~~~~~


Found 1 error.

since 3.7.5 to 3.8.3 is not a semver breaking change

TypeScript does not follow SemVer: #14116 (comment)

[rmainwork]

...oh.

...Well that's "fun".

Thanks for the heads up I guess.

Duplicate of #36917

There are good reasons to not follow SemVer. :-) You can read about them in #14116.

Also you can check out #36917, which mentions why noEmit and incremental is not allowed/supported together.

Yeah, thanks. I'm reading the thread just now...the only problem is that I'm pinned to 3.5.2 and getting 3.8.x.

If typescript doesn't follow semver...is there an explanation somewhere of what the version numbers actually mean? Do they mean anything at all?
