-# not yet published, version 6.2.2
+# 2020-01-08, version 6.5.0
 
+- Implemented `baseName` option for `createUnit`, see #1707. 
+  Thanks @ericman314.
+
+
+# 2020-01-06, version 6.4.0
+
+- Extended function `dimension` with support for n-dimensional points.
+  Thanks @Veeloxfire.
+
+
+# 2019-12-31, version 6.3.0
+
+- Improved performance of `factorial` for `BigNumber` up to a factor two,
+  see #1687. Thanks @kmdrGroch.
+
+
+# 2019-11-20, version 6.2.5
+
+- Fixed `IndexNode` using a hardcoded, one-based implementation of `index`,
+  making it impossible to instantiate a zero-based version of the expression
+  parser. See #782.
+
+
+# 2019-11-20, version 6.2.4
+
+- Fixed #1669: function 'qr' threw an error if the pivot was zero,
+  thanks @kevinkelleher12 and @harrysarson.
+- Resolves #942: remove misleading assert in 'qr'. Thanks @harrysarson.
+- Work around a bug in complex.js where `sign(0)` returns complex NaN.
+  Thanks @harrysarson.
+
+
+# 2019-10-06, version 6.2.3
+
+- Fixed #1640: function `mean` not working for units. Thanks @clintonc.
+- Fixed #1639: function `min` listed twice in the "See also" section of the
+  embedded docs of function `std`.
+- Improved performance of `isPrime`, see #1641. Thanks @arguiot.
+
+
+# 2019-09-23, version 6.2.2
+
+- Fixed methods `map` and `clone` not copying the `dotNotation` property of
+  `IndexNode`. Thanks @rianmcguire.
+- Fixed a typo in the documentation of `toHTML`. Thanks @maytanthegeek.
 - Fixed #1615: error in the docs of `isNumeric`.
+- Fixed #1628: Cannot call methods on empty strings or numbers with value `0`.

 * **prefixes** A `string` indicating which prefixes math.js should use with the new unit. Possible values are `'none'`, `'short'`, `'long'`, `'binary_short'`, or `'binary_long'`. Default is `'none'`.
 * **offset** A value applied when converting to the unit. This is very helpful for temperature scales that do not share a zero with the absolute temperature scale. For example, if we were defining fahrenheit for the first time, we would use: `math.createUnit('fahrenheit', {definition: '0.555556 kelvin', offset: 459.67})`
 * **aliases** An array of strings to alias the new unit. Example: `math.createUnit('knot', {definition: '0.514444 m/s', aliases: ['knots', 'kt', 'kts']})`
+* **baseName** A `string` that specifies the name of the new dimension in case one needs to be created. Every unit in math.js has a dimension: length, time, velocity, etc. If the unit's `definition` doesn't match any existing dimension, or it is a new base unit, then `createUnit` will create a new dimension with the name `baseName` and assign it to the new unit. The default is to append `'_STUFF'` to the unit's name. If the unit already matches an existing dimension, this option has no effect.
 
 An optional `options` object can also be supplied as the last argument to `createUnits`. Currently only the `override` option is supported:
