 The following list summarizes some of these updates:
 
-* **Typescript support:** This new version has been completely re-written using Typescript. This means we now have well-defined types that increases the developer experience. 
-* **Standard naming convention:** Functions, methods, classes, and variable names have been standardized to follow JavaScript best practices. 
-* Standardize function argument: Functions and methods have been updated to accept arguments and parameters intuitively resulting in improved developer experience.

 * **New features**: We added lots of new features which users have been requesting for. For example:
   * Stream and process large CSV data
-  * Read JSON objects with key support
-  * Date time is now a first-class data type.
 * General bug fixes and improvements
 * Better error messages

 ### Functions and Methods argument structure
 
 Another major breaking change of v1, is that the structure of arguments/parameters in most functions has been updated to be more intuitive.
 
 In general, it is important to understand our thought process behind this, so, here goes:
 
-Assuming we take the method called _**rename**_, which takes  required object mapper, as well as, optional configuration argument. In pre-v1 version of Danfojs, the function signature is as follows:

 ### Axis Order
 
 In this new version, we have flipped the result of the axis ordering for all operations. This ordering is now consistent with Pandas and Tensorflow.js. That is, the axis row (0), represents the operations carried out horizontally on a DataFrame, and the axis columns (1) represent operations carried out vertically down the DataFrame.
 
 {% hint style="info" %}
-In short, when migrating to the new version, you should flip the axis number so as to get the same result. That is, change all `axis: 0` to `axis: 1`, to get the same result.
