Version 2.0.0-beta1

First beta of the C++17 rewrite, shipping alongside the existing tool.

Nothing is renamed. slowhttptest is still the 1.10.0 tool you already run.
The rewrite installs next to it as slowhttptest-ng, with its own man page.

slowhttptest-ng -u https://target/ -c 1000 -H
docker run --rm shekyan/slowhttptest:ng -u https://target/ -c 1000 -H

What it adds

• HTTP/2 attacks: slow read (CVE-2019-9517), rapid reset
  (CVE-2023-44487), CONTINUATION flood — verified against nginx 1.31.4.
• A verdict, not a socket census — HTML and JSON reports that say
  whether service was denied, with the caveats that qualify it.
• kqueue on macOS/BSD, which is the only way past ~10k connections there.
• Availability probing (-p), a capacity staircase, and exit code 3
  meaning nothing was actually tested — the failure that used to pass CI.

Deliberate incompatibilities

Flag compatibility is otherwise complete. Three things differ on purpose:

• CSV output is gone; JSON carries the same event log plus the verdict.
• Exit codes are 2/3 rather than -1.
• The report is written around availability rather than socket states.

Falling back

Both binaries ship in this release. If slowhttptest-ng doesn't suit you,
slowhttptest is still installed and unchanged — no reinstall, no downgrade.

Marked pre-release deliberately: packaging tooling that follows the latest
release will keep tracking 1.10.0 until the rewrite has had real exposure.
