It consists of an <a href="#Integer_literals">integer</a> or

followed by the lowercase letter <code>i</code>.
The value of an imaginary literal is the value of the respective

  CVE-2021-29923 golang standard library "net" - Improper Input Validation of octal literals in golang 1.16.2 and below standard library "net" results in indeterminate SSRF & RFI vulnerabilities.

* Fixed an issue where commas were not accepted in --from-literal flags for the creation of secrets. ([#35191](https://github.com/kubernetes/kubernetes/pull/35191), [@SamiHiltunen](https://github.com/SamiHiltunen))
  * Passing multiple values separated by a comma in a single --from-literal flag is no longer supported. Please use multiple --from-literal flags to provide multiple values.

  // cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced
  // to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will
  // produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless
  // of whether the variable exists or not. Cannot be updated.

- `kube-proxy`: Added an option/flag for configuring the `nf_conntrack_tcp_be_liberal` sysctl (in the kernel's netfilter conntrack subsystem).  When enabled, `kube-proxy` will not install the `DROP` rule for invalid conntrack states, which currently breaks users of asymmetric routing.

  optional. If the value is not provided i.e., the command looks like `wait --for=jsonpath='{expression}'`
  then the wait condition is interpreted as matched when the expression returns
  *any* single JSON value like object or a literal. ([#118160](https://github.com/kubernetes/kubernetes/pull/118160), [@minherz](https://github.com/minherz))
