v1.9.4

1.9.4 (August 18, 2023)

BUG FIXES:

• core: When invoking Packer with the CHECKPOINT_DISABLE environment variable the telemetry
  reporter is left uninitialized in order to disable telemetry reporting.
  Any method calls on the nil reporter is expected to check if the reporter is active or in
  NOOP mode. The SetBundledUsage function, introduced in Packer 1.9.2, failed to perform a nil
  check before attempting to modify an attribute, causing Packer to fail when telemetry is
  disabled. This release fixes this issue by introducing such a check.
