  41 version 0.4.0:
  42   - swtpm:
  43     - Invoke print capabilities after choosing TPM version
  44     - Add some recent syscalls to seccomp blacklist
  45   - swtpm_cert:
  46     - Support --ecc-curveid option to pass curve id
  47   - swtpm_setup & related scripts:
  48     - Rewrite swtpm_setup.sh in python with TPM 1.2 not requiring tcsd
  49       and TPM tools anymore; new dependencies:
  50       - python3: pip, cryptography, setuptools
  51       dropped dependencies for swtpm_setup:
  52       - tcsd, expect, tpm-tools (some still needed for pkcs11 tests)
  53     - Added support for RSA 3072 keys (for libtpms-0.8.0) and moved to
  54       ECC NIST P384 curve; default RSA key size is still 2048
  55     - Added support for --rsa-keysize option
  56     - Extend script to create a CA using a TPM 2 for signing
  57   - tests:
  58     - Use the IBM TSS2 v1.5.0's test suite
  59     - Add test case for loading of an NVRAM completely full with keys
  60     - Have softhsm_setup use temporary directory for softhsm config & state
  61     - various other improvements

  99            libseccomp support
 100   - Added subpport for passing key and passphrase via file descriptor
