Improvements
Annotations [PLFM-6530] - Entities can be annotated using boolean datatypes. You can now validate Synapse annotations with boolean datatypes using JSON schema.
Personal access tokens for Python and R clients [SYNPY-1058] - Synapse now supports login using access tokens if you use the Python or R programmatic clients. Using a token is preferred over a username and password because tokens can be more easily revoked if they are compromised. Additionally, tokens can be scoped to limit their access within Synapse, rather than a username and password that automatically grant full access to your account.
/wiki/spaces/DOCS/pages/1985151345 [CHL-13] - The user interface for scheduling challenge rounds and submission limits is now easier to use. Submission rounds are defined by an explicit start and end date that you define from a calendar, and optional submission limits can be set to daily, weekly, or monthly.
New Synapse Homepage - The Synapse homepage looks better than ever before, and now includes links to community-specific knowledge portals driven by Synapse.
