+Düsseldorf sprint report
+
+Hello everyone!
+
+We are happy to report a successful and well attended sprint that is wrapping up
+in Düsseldorf, Germany. In the last week we had eighteen people sprinting at the
+Heinrich-Heine-Universität Düsseldorf on various topics. Big chunk of the sprint
+was dedicated to various discussions, since we did not manage to gather
+core developers in one room in quite a while. Discussion topics included:
+
+* Funding and general sustainability of open source.
+
+* Catching up with CPython 3.7/3.8 - we are planning to release 3.6 some time
+  in the next few months and we will continue working on 3.7/3.8.
+
+* What to do with VMprof
+
+* How can we support Cython inside PyPy in a way that will be understood
+  by the JIT, hence fast.
+
+* The future of supporting the numeric stack on pypy - we have made significant
+  progress in the past few years and most of numeric stack works out of the box,
+  but deployment and performance remain problems. Improving on those problems
+  remain a very important focus for pypy as a project.
+
+* Using the presence of CPython developer (Łukasz Langa) and Graal python developer
+  (Tim Felgentreff) we discussed ways to collaborate in order to improve python
+  ecosystem across implementations.
+
+* Pierre-Yves David and Georges Racinet from octobus gave us an exciting demo
+  on `Heptapod`_, which adds mercurial support to gitlab.
+
+Some highlights of the coding tasks worked on:
+
+* Aarch64 (ARM64) JIT backend work has been started, we are able to run the first
+  test! Tobias Oberstein from Crossbar GmbH and Rodolph Perfetta from ARM joined the
+  sprint to help kickstart the project.
+
+* Long running math-improvements branch that was started by Stian Andreassen got merged
+  after bugfixes done by Alexander Schremmer. It should improve operations on large integers.
+
+* Arcane art of necromancy was used to revive long dormant regalloc branch started
+  and nearly finished by Carl Friedrich Bolz-Tereick. The branch got merged and gives
+  some modest speedups across the board.
+
+* Andrew Lawrence worked on MSI installer for PyPy on windows.
+
+* Łukasz worked on improving failing tests on PyPy 3.6 branch. He knows very obscure
+  details of CPython, hence we managed to progress very quickly on the 3.6 branch.
+
+* Matti Picus set up new benchmarking server for PyPy 3 branches.
+
+* Utf8 branch, which changes the internal representation of unicode might be finally
+  merged at some point very soon. That gives significant speedups in a lot of cases
+  handling strings.
+
+* Zlib was missing couple methods, which were added by Ronan Lamy and Julian Berman.
+
+* Manuel Jacob fixed RevDB failures.
+
+* Antonio Cuni and Matti Picus worked on 7.0 release which should happen in a few days.
+
+Best regards,
+Maciej Fijałkowski, Carl Friedrich Bolz-Tereick and the whole PyPy team.
