With v4 you started to get a deprecation warning `String based operators are now deprecated`. Also concept of operators was introduced. These operators are Symbols which prevent hash injection attacks.

**With v5**
- Operators are now enabled by default.
- You can still use string operators by passing an operators map in `operatorsAliases`, but that will give you deprecation warning.

**Model.bulkCreate**
`updateOnDuplicate` option which used to accept boolean and array, now only accepts non-empty array of attributes. [#9288](https://github.com/sequelize/sequelize/issues/9288)
**Underscored Mode**
Implementation of `Model.options.underscored` is changed. You can find full specifications [here](https://github.com/sequelize/sequelize/issues/6423#issuecomment-379472035).
Main outline
1. Both `underscoredAll` and `underscored` options are merged into single `underscored` option
2. All attributes are now generated with camelcase naming by default. With the `underscored` option set to `true`, the `field` option for attributes will be set as underscored version of attribute name.
3.`underscored` will control all attributes including timestamps, version and foreign keys. It will not affect any attribute which already specifies the `field` option.

* @param {Array} [options.retry.match] Only retry a query if the error matches one of these strings.
* @param {Integer} [options.retry.max] How many times a failing query is automatically retried. Set to 0 to disable retrying on SQL_BUSY error.

* @param {Boolean} [options.typeValidation=false] Run built in type validators on insert and update, e.g. validate that arguments passed to integer fields are integer-like.
* @param {Object|Boolean} [options.operatorsAliases=true] String based operator alias, default value is true which will enable all operators alias. Pass object to limit set of aliased operators or false to disable completely.
* @param {Object} [options.operatorsAliases] String based operator alias. Pass object to limit set of aliased operators.
