+## JuMP-Dev 2021
+
+We were excited to have the JuMP-dev conference co-located within JuliaCon for the first time this year. It was an awesome opportunity to get the users and developers from the JuMP-dev community engaged with the greater Julia community. You can check out the JuMP videos from conference in [this JuMP dedicated playlist](https://youtube.com/playlist?list=PLP8iPy9hna6Rf8_oh9oR2bNeBO-Rw8pzc).

+## Code, Docs and Tests: What’s In the General Registry?
+
+Mosè Giordano and Eric P. Hanson presented [Code, Docs and Tests: What’s In the General Registry?](https://live.juliacon.org/talk/HVSAW9)  
+
+The General registry is the collection of open source packages that makes up the Julia package ecosystem. The Julia General registry has **11.8 million lines of code** (including docs and tests). More than 96% of packages have an Open Source Initiative approved license, 88% have at least 20 lines of readme or docs, 96% have run tests, 95% have setup for continuous integration, 58% of packages have at least 2 contributors, 93% have at least 10 commits, 48% of contributors have contributed to two or more packages and 60% of contributors have made at least 5 commits. There are 4,931 Julia contributors who have contributed to packages in the General registry. You can read more in depth on the [blog post by Mosè and Eric](https://julialang.org/blog/2021/08/general-survey/) on the Julia Language's blog.
+
+## State of Julia

+
+These include speed increases for CSV.jl and DataFrames.jl, packages reaching 1.0, threading roadmap, faster method insertion, small type info improvements, inference improvements, subtyping and intersection fixes and speedups, CI stability, latency, system images, array optimizations, GC performance, compiler extensibility, new compiler directions, AbstractInterpreter, OpaqueClosure, compiler plugins, Automatic Differentiation, BLAS, sparse matrices and linear algebra.
