+### Added
+- Added minimal bash completion via [taywee/args][taywee/args].
+- Added ``--version`` option.
+- New algorithms:
+  - Crasher, whose purpose is to crash :).
+    This is useful to test execution managers.
+  - EnergyWatcher, whose purpose is just to query the energy consumption to
+    Batsim
+  - Random, whose purpose is notably to test time-sharing.
+  - Sequencer, which is very simple and whose purpose is to be the base of
+    other testing algorithms.
+  - WaitingTimeEstimator, whose purpose is only to test the support of the
+    ``estimate_waiting_time`` QUERY.
+
+### Changed
+- Batsched arguments are now parsed by [taywee/args][taywee/args]
+  rather than [boost::po][boost::po].
+- Support Batsim version 2.0.0:
+  - two-way QUERY/REPLY (+estimate_waiting_time)
+  - SET_JOB_METADATA
+- Changed algorithms:
+  - Conservative BF now supports the ``estimate_waiting_time`` QUERY.
+  - Filler now supports a custom mapping and setting job metadata.
+  - Submitter now supports setting job metadata.
