The modern history of optimizations for Erlang begins in January 2018. We had realized that we had reached the limit of the optimizations that were possible working on BEAM code in the Erlang compiler.

• Erlang/OTP 22 introduced a new SSA-based intermediate representation in the compiler. Read the full story in SSA History.

• Erlang/OTP 24 introduced the JIT (Just In Time compiler), whic...
