| :----------- | :-------------- | :----------- |
| April 2021 | `v14.0` | 04/01/2021 |
*Released on 4/1/2021*
**DEPRECATION NOTICE -- v4 API ENDPOINT**
We released the v5 person/enrich API endpoint in [July of 2020](/changelog/q2-2020-release-notes). We will **end of life** the v4 person/enrich and person/bulk endpoints during our **October 2021** release. We will end support and maintenance for the v4 endpoint in July 2021. We’ll continue to push new data updates to the v4 endpoint until the End of Life date.\
Please reach out to your Customer Success team at PDL if you have any questions or need assistance with the migration.
**DEPRECATION NOTICE -- Canonical Company Data**
We are continuing to put the "canonical" location, school, and company files in s3://pdl-prod-schema. We expect to deprecate school.jsonl, location.jsonl, and company.jsonl files at the end of this year, while providing this relational data via complimentary access to our [Cleaner Endpoints](/docs/cleaner-apis) for all customers.
### Data Field Changes
#### [Person Schema](/docs/fields)
| Field Name | Field Type | Field Description | Change in v14 |
| :--------------- | :------------ | :------------------------------------------------------- | :-------------- |
| personal\_emails | List (String) | An array of all personal emails associated with a person | New field added |
### Freshness
This quarter, we made great strides in updating our datasets and have updated job titles for over **315mm** of our global profiles and locations for over **344mm**. We also updated jobs for **88mm** of our United States profiles and locations for **95mm**. Most of the profiles with updated jobs have had their full resume refreshed, not just their current job.
### Coverage
We are continuing to make strides to link more PII to our core datasets. See some highlights below and click the links on each slice to see the full set of stats for each.

### Commentary
* We’ve dramatically increased our mobile phone coverage by 72%. All of these new mobile phones are tied to a facebook URL and primarily bolster our global phone coverage.
* We’ve also increased the linkage of mobile phone to resume data by 72%, from \~7.4mm to \~12.8mm
* We’ve expanded the number of resumes in our person dataset, increasing the total size of our resume slice by \~10%, and increasing the fullness of our resume profiles. One metric for understanding the fill rates of our resumes is the **job\_start\_date** field, whose coverage increased \~45%
### Improvements
* We’ve added the ability to [enrich profiles using MD-5 hashed emails](/docs/enrichment-api#email-hash) in our Enrichment API. These can be inputted in the **email\_hash** parameter.
* Our canonical company coverage of our person dataset has improved from 65% to 69%
* We added deduplication processes that increased the work email coverage and mobile phone coverage in our resume slice
* Our internal data build/release were revamped to help us output more in each future release
* We are launching an internal API usage analysis tool so our customer success team can help optimize API usage to reduce errors and help customers increase the likelihood scores they get back.
* We will be releasing a new customer facing API dashboard at [peopledatalabs.com/main](https://peopledatalabs.com/main)
### Bug Fixes
* We removed a data source with some inferred emails.
* We added additional filtering to remove a small set of records with an abnormally large number of phones or addresses.
* We fixed issues with foreign job title encoding
## April 1, 2021 Self-Serve API Changes
We hope you’ve been getting tremendous value from your People Data Labs experience to date. Firstly, we wanted to thank you for being a PDL customer and for utilizing our Pay as you Go API services via our Self Service. Originally, our Pay as you Go model was intended to support low volume usage and encourage people to try out our product without committing to an annual subscription. While we believe that this has been successful, we also believe that it is no longer serving the needs of our customers in the best way possible.
As a result of that,we will be deprecating this option and replacing it with a monthly committed package model starting on April 1, 2021. In conjunction with that change, we’ll also be releasing a new API dashboard that includes public access to our Person Search and Company Enrichment endpoints.
What does this mean for you? If you would like to continue using PDL data past March 31st, 2021, you will need to select one of our monthly-committed API packages based on what your needs are. Of course, we don’t want to break your existing application, so on April 1st you’ll lose unlimited access, but we’ll grant you a one-time additional 5,000 matches towards our person enrichment API for free. Think of this as a bridge that will get you started on our new monthly, pre-paid, package. We encourage you to visit your API dashboard and choose your committed package if you’d like to continue using PDL -- this is very important. The minimum committed package will continue to be \$.25 a match and will require a 1,000 match / month minimum commitment. However, a committed model will allow us to provide higher discounted tiers at 2,500 and 5,000 committed matches monthly, which many of our Pay as you Go customers have already been hitting consistently over time.
If you have any questions, feel free to reach out to us. We’re committed to making this as smooth of a transition as possible.
