The %c specifier is ignored now.v12.11.0https://github.com/nodejs/node/pull/29606
The format argument is now only taken as such if it actually contains format specifiers.v12.0.0https://github.com/nodejs/node/pull/23162
If the format argument is not a format string, the output string's formatting is no longer dependent on the type of the first argument. This change removes previously present quotes from strings that were being output when the first argument was not a string.v12.0.0https://github.com/nodejs/node/pull/23162
The %d, %f, and %i specifiers now support Symbols properly.v11.4.0https://github.com/nodejs/node/pull/23708
The %o specifier's depth has default depth of 4 again.v11.4.0https://github.com/nodejs/node/pull/24806
The %o specifier's depth option will now fall back to the default depth.v11.0.0https://github.com/nodejs/node/pull/17907
The %d and %i specifiers now support BigInt.v10.12.0https://github.com/nodejs/node/pull/22097
The %o and %O specifiers are supported now.v8.4.0https://github.com/nodejs/node/pull/14558
