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 revoked if they are compromised, and because they can be scoped to have access only to certain things in Synapse, rather than your entire 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.
