prebid/prebid-server v2.0.0 on GitHub

Major Release

This release marks the first time we've incremented Prebid Server's major version, bringing substantial changes that warrant extra attention and vetting from host companies before deployment. For further details, consult the Prebid Server 2.0 Release issue.

Changes include:

Six bidders have been removed. Please see the linked issue and ensure these adapters aren't used by your publishers. We hope some adapters will return to the project in the future. If you have current contact information for any of these adapters, please have them reach out to us at prebid-server(at)prebid.org.
The encoding/json package from the standard Go library is replaced by JSON-Iterator in core code (not yet adapters), resulting in a 300% performance improvement for encoding/decoding OpenRTB payloads. While our rigorous testing looks good, we highly recommend thorough testing with your own traffic. Please report any edge cases or bugs in a new issue. It is expected for encoding error messages to be different.
Bidder codes are now case insensitive. This should not affect the reponse or analytics. However, metrics now report bidder names in lowercase. For example, the "stroerCore" adapter is now logged to metrics as "stroercore". Please update your dashboards and alerts accordingly.
In previous updates to Prebid Server 0.x, we've strived to preserve backward compatibility with deprecated configuration. In this release, we've discontinued this backward compatibility as part of a tech debt cleanup effort. Host companies are required to migrate to the updated configuration with this release.
We've improved the setup of hardcoded aliases, streamlining the process to require just one configuration file and no code. Half of the aliases are migrated in this release, with the remainder planned for migration in version 2.1.0.
