# January 2020 Release Notes

<Update label="01/09/2020">
  ## January 2020 Release Notes (v9.0)

  | Release Name | Dataset Version | Publish Date |
  | :----------- | :-------------- | :----------- |
  | January 2020 | `v9.0`          | 01/09/2020   |

  *Released on 1/09/2020*

  ### Freshness

  * This quarter we have refreshed **132mm** of our global work experience data.
  * Similarly, we have refreshed **48mm** of our US work experience data
  * We’ve also refreshed locations for **92mm** profiles globally and **45mm** profiles in the United States

  ### Coverage Increase

  We’ve improved and added data to the following fields:

  * Industries -- **9mm** increase
  * Work Experience -- **28mm** increase
  * Education -- **15mm** increase
  * Location -- **36mm** increase

  ### Data Field Changes

  There have been no changes in any API params or data license schema this build.

  ### Minor Improvements

  * Increased coverage and updated github profiles in the API dataset
  * Improved title tagging led to lift in the amount of profiles categorized as “manager+” in the `experience.title.levels` field. We expanded the definition of a few levels, most significantly the "manager" level, which may yield some more false positive tags, but avoids significantly more false negatives.

  ### Data Pipeline Improvements

  A significant amount of engineering resources was allocated to refactoring our data pipeline this quarter. Going into 2020 this will allow us to ingest and validate data sources significantly faster. From a customer standpoint, we’ll be able to start working towards the following goals starting with our January 2020 build:

  * Increase coverage of social profiles and emails by including previous “untrusted” sources, without causing false positive merges. We will flag these data points when we release them so they can be filtered out if you so choose.
  * Ingest data and validate in real time, allowing us to keep data points more up to date, moving the time delta between our last\_updated dates and the data releases closer together and making them more accurate
  * Begin exploring a wider breadth of data partnerships without compromising our data quality using the “untrusted” methodology with any new sources that we haven’t been able to allocate hand-validation resources to yet. Any customers interested in becoming a data union partner (who aren't already) should reach out to us on slack or via [success@peopledatalabs.com](mailto:success@peopledatalabs.com)
