+ 
+   The community added 7 new contributors that submitted pull-requests which
+   were merged into master.
+ 
+   The number of users approaching the team on the Slack channel has kept
+   steadily increasing since the last report. Many users have actively deployed
+   Pulsar for evaluation and production use cases.
+ 
+   Project members from several companies have organized or participated in
+   several meetups, presenting Pulsar's introductions, deep-dives and hands-on
+   tutorial, including recorded podcasts. We have several scheduled talks on
+   Pulsar at various conferences, 2 at ApacheCon in September, one at OSCon in
+   July and 2 others at Strata New York in September. A Pulsar dedicated meetup
+   is being organized for next July.
+  
+   Since the last report the number of weekly-active-users on the Slack channel
+   has increased from 53 to 88.
+  
+   We have reached the 1 year mark since Pulsar entering the Apache Incubator.
+   Here is a summary of the community developments over the past year:
+  
+  
+   1. Pulsar community has done 5 Apache releases since entering
+      incubator. The release process is well documented and we have
+      had 4 different release managers from 3 different companies.
+    
+   2. We have added 3 committers and PPMC members since incubation and
+      there are also other candidates who have already made significant
+      contributions to the project.
+    
+   3. Community of users and people interested in Pulsar has expanded
+      considerably. Thanks to the months long work in improving ease of
+      use, documentation and blogs, many people became aware of Pulsar
+      and started playing with it, then evaluating it and finally
+      putting it in production for critical use cases.
+    
+   4. We have tried to help users getting started through any
+      communication channel. Even though we keep trying to encourage
+      people to use the mailing list, most of the first interactions
+      have been happening through the Slack channel. We also did make
+      sure that:
+   
+      a) No decisions are taken in Slack channel
+    
+      b) Developers technical discussion happen mostly in Github
+         issue/Pull-Request or in developers mailing list
+    
+      c) Conversations in Slack are sent to dev/user mailing list in a
+         daily digest form for archival and to be searchable
+  
+      In any case Slack has been working fairly well in engaging with
+      users, by providing a tool to have very quick informal
+      question/answer interactions that were very appreciated by users.
+ 
+    5. Overall, there were a lot of healthy discussions, with feedback
+       and collaborations from people from different companies and
+       different perspectives that resulted in much stronger design
+       decisions and ultimately a better system.
+ 
+    6. We have taken several steps to increase awareness, like blog
+       posts, meetups (both dedicated to Pulsar or dedicated to similar
+       topics) and presentations to conferences, like Strata or
+       ApacheCon (where we have 2 talks scheduled for next September).
+ 
+ How has the project developed since the last report?
+ 
+   23 authors have pushed 469 commits to master in the last 3 months.
+ 
+   The project has made the its fifth release since joining the
+   Apache Incubator (2.0.0-rc1-incubating on May 29th). This was a
+   major release that culminated several months of works and lays the
+   foundation for the next stage in Pulsar development. New major
+   features include:
+    * Pulsar Functions (Lightweight compute framework)
+    * Schema registry
+    * Topic compaction
+   
+   Community is actively working on next milestone, 2.1 release that
+   will include several new features including:
+    * Pulsar IO connector framework
+    * Tiered storage
+    * Go client library
+ 
+   Since March, 3 new PIPs (Pulsar Improvement Proposals) for major
+   feature/changes, have been submitted to the wiki and discussed in the
+   mailing list.
+  
+   To recap the project developments since entering Apache Incubator:
+  
+   1. Moved to Apache BookKeeper 4.7. Before Pulsar 2.0, we were using
+      a fork of BookKeeper from Yahoo, based on 4.3.1 with 245
+      additional commits. Thanks to a a big effort in the BookKeeper
+      community (which has a large overlap with Pulsar community), all
+      these changed were merged back into mainstream BookKeeper branch
+      and released in BookKeeper 4.7.0, making possible for Pulsar to
+      switch over from the Yahoo fork.
+ 
+   2. We have received a lot of feedback from people approaching Pulsar
+      and learned a lot on how to simplify tools, documentation and
+      concepts to make it easier for people to get started.
+    
+   3. Based on the same feedback and inputs, we have been adding new
+      features or extended existing features to match a new variety of
+      use case, some of them outside the scope the initial Pulsar
+      codebase from Yahoo.
+ 
+      To summarize the "major" features added in the last year:
+ 
+       - Pulsar stateless proxy
+       - Non-persistent topics
+       - End-to-End message encryption
+       - Effectively-once semantics
+       - Type-safe APIs
+       - Schema Registry
+       - Pulsar Functions
+       - Topic compaction
+       - Python client library
+     
+     With more scheduled for next upcoming release 2.1:
+   
+       - Pulsar IO connector framework
+       - Tiered storage
+       - Go client library
+     
+   4. In addition to features, we have been trying to smooth the
+      deployment of a production ready Pulsar cluster, by improving the
+      documentation and providing templates for more common environments,
+      such as Kubernetes, DCOS or just plain VMs with Ansible.
+ 
+   5. Having exposure to many users testing and using the sytem outside
+      the original Yahoo use cases has proven very effecting in helping
+      identifying and resolving corner cases that were not being
+      stressed before. This resulted in a much resilient system that
+      can adapt better to a large array of different requirements and
+      environments.
  
  
  How would you assess the podling's maturity?
