## Description:
Pulsar is a highly scalable, low latency messaging platform running on
commodity hardware. It provides simple pub-sub semantics over topics,
guaranteed at-least-once delivery of messages, automatic cursor management for
subscribers, and cross-datacenter replication.

- The serie of by-weekly virtual community meetings for committers
and community members that was started in the past quarter is
still going strong. In both meetings, there are always healthy
discussions on the current issues in the project, new proposals
and ideas bounced with other developers. The participation is
open to anyone and the minutes of these meetings are posted to the
dev@ mailing list.
- The second edition of Pulsar Summit North America is scheduled
for next week, June 16, 17 2021. The agenda includes 5 keynotes
and 33 talks, divided in 3 tracks: Deep dive, Use cases and
Ecosystem.
- Next release 2.8.0 is being voted. There have been 2 release
candidates and since the community has found few issues in the
latest build, we are working to prepare a 3rd release
candidate.
