Around the beginning of January 2019 Pixabay changed the type of license they apply to their content.
Before the change Pixabay used the Creative Commons license “CC0” which dedicates works to the public domain.
The CC0 license does this by enabling owners of copyright or database-protected content to waive those interests in their works, thereby allowing anyone to build upon, enhance and reuse said works for any purposes without restriction under copyright or database law.

Pixabay have now created their own license called the “Pixabay License”. Although this new license has similarities to the CC0 license, it has added restrictions to how you may use Pixabay content, which were not present before with the CC0 license.
The new restrictions are linked to how you may use Pixabay’s content, so make sure you read up on this new license before using Pixabay content.
In conjunction, it is also worth noting that Pixabay appears to have applied this license change to content which was already under the CC0 license.

If you don’t know what Pixabay is – Pixabay is a free stock media website providing photos, videos, illustrations and vector graphics, uploaded by its global community of contributors. Whether for personal or commercial use, anyone can download and use Pixabay’s content for free without obtaining permission or giving credit to the artist or Pixabay itself. Up until recently this was under the CC0 license, but now it’s under the more restrictive Pixabay License.
