+Sidekiq Pro Changelog
+=======================
+
+
+1.0.0
+-----------
+
+- Sidekiq Pro changelog moved to mperham/sidekiq for public visibility.
+- Add new Rack endpoint for easy polling of batch status via JavaScript.  See `sidekiq/rack/batch_status`
+
+0.9.3
+-----------
+
+- Fix bad /batches path in Web UI
+- Fix Sinatra conflict with sidekiq-failures
+
+0.9.2
+-----------
+
+- Fix issue with lifecycle notifications not firing.
+
+0.9.1
+-----------
+
+- Update due to Sidekiq API changes.
+
+0.9.0
+-----------
+
+- Rearchitect Sidekiq's Fetch code to support different fetch
+strategies.  Add a ReliableFetch strategy which works with Redis'
+RPOPLPUSH to ensure we don't lose messages, even when the Sidekiq
+process crashes unexpectedly. [mperham/sidekiq#607]
+
+0.8.2
+-----------
+
+- Reimplement existing notifications using batch on_complete events.
+
+0.8.1
+-----------
+
+- Rejigger batch callback notifications.
+
+
+0.8.0
+-----------
+
+- Add new Batch 'callback' notification support, for in-process
+  notification.
+- Symbolize option keys passed to Pony [mperham/sidekiq#603]
+- Batch no longer requires the Web UI since Web UI usage is optional.
+  You must require is manually in your Web process:
+
+```ruby
+require 'sidekiq/web'
+require 'sidekiq/batch/web'
+mount Sidekiq::Web => '/sidekiq'
+```
+
+
+0.7.1
+-----------
+
+- Worker instances can access the associated jid and bid via simple
+  accessors.
+- Batches can now be modified while being processed so, e.g. a batch
+  job can add additional jobs to its own batch.
+
+```ruby
+def perform(...)
+  batch = Sidekiq::Batch.new(bid) # instantiate batch associated with this job
+  batch.jobs do
+    SomeWorker.perform_async # add another job
+  end
+end
+```
+
+- Save error backtraces in batch's failure info for display in Web UI.
+- Clean up email notification a bit.
+
+
+0.7.0
+-----------
+
+- Add optional batch description
+- Mutable batches.  Batches can now be modified to add additional jobs
+  at runtime.  Example would be a batch job which needs to create more
+  jobs based on the data it is processing.
+
+```ruby
+batch = Sidekiq::Batch.new(bid)
+batch.jobs do
+  # define more jobs here
+end
+```
+- Fix issues with symbols vs strings in option hashes
+
+

+
+0.6
