 ### Breaking
 
  * This release involved a substantial rewrite of Convex.jl to integrate better

+   with MathOptInterface. (#504), (#551), (#584), (#588), (#637)
     * `x + A` will error if `x` is a scalar variable and `A` is an array.
       Instead, use `x * ones(size(A)) + A`.
     * The `RelativeEntropyAtom` now returns a scalar value instead o

       (Following the convention in MathOptInterface, the dual of `a <= b` is
       always negative, regardless of optimization sense.) (#593)
     * The structs `LtConstraint`, `GtConstraint`, `EqConstraint`
-      `SOCConstraint` and `SDPConstraint` have

+    * The set `GeomMeanEpiCone` has been renamed to `GeometricMeanEpiConeSquare`
+      and `GeomMeanHypoCone` has been renamed to `GeometricMeanHypoConeSquare`
+      (#638)
+ * **Subtle breaking change**: scalar row indexing like `x[i, :]` now produces a
+   column vector instead of a row vector. This better aligns with Julia Base,
+   but it can result in subtle differences, particularly for code like
+   `x[i, :] * y[i, :]'`: this used to be equivalent to the inner product, but it
+   is now the outer product. In Base Julia, this is the outer product, so the
+   previous code may be been silently broken (#624)
  * The syntaxes `dot(*)`, `dot(/)` and `dot(^)` have been removed in favor of
    explicit broadcasting (`x .* y`, `x ./ y`, and `x .^ y`). These were (mild)
    type piracy. In addition, `vecdot(x,y)` has been removed. Call

  * DCP violations now throw a `DCPViolationError` exception, rather than a
    warning. Relatedly, `Convex.emit_dcp_warnings` has been removed (#523)
- * Removed the undocumented an internal function `latex_formulation` (#551)
  * The strict inequalities `>` and `<` have been deprecated. They will be
    removed in the next breaking release. Note that these never enforced strict
    inequalities, but instead were equivalent to `>=` and `<=` respectively (#555)
  * The functions `norm_inf`, `norm_1`, and `norm_fro` have been deprecated. They
    will be removed in the next breaking release (#567)
+ * The syntax `x in :PSD` to create a semidefinite constraint is deprecated and
+   will be removed in the next breaking release (#578)
+ * Fixed setting a `Constant` objective function. This is breaking because it
+   now has an objective sense instead of ignoring the objective. (#581)
+ * `quadform` now errors when fixed variables are used instead of silently
+   giving incorrect answers if the value of the fixed variable is modified
+   between solves (#586)
+ * The `Context` struct has been refactored and various fields have been
+   changed. The internal details are now considered private. (#645)
 
 ### Added
 
  * SDP, SOC, and exponential cone constraints now have dual values populated
    (#504)
  * `geomean` supports more than 2 arguments (#504)
  * Added `Convex.Optimizer` (#511), (#530), (#534)

+ * Added `write_to_file` (#531), (#591)
  * Added `entropy_elementwise` (#570)
  * `norm` on `AbstractExpr` objects now supports matrices (treating them like
    vectors), matching Base's behavior (#528)
+ * Added `root_det` (#605)
+ * Added `VcatAtom` which is a more efficient implementation of `vcat` (#607)
+ * Added support for `SparseArrays.SparseMatrixCSC` in `Constant`. This fixed
+   performance problems with some atoms (#631)
+ * `solve!` now reports the time and memory allocation during compilation from
+   the DCP expression graph to MathOptInterface (#633)
+ * Added support for using `Problem` as an atom (#646)
+ * `show(::IO, ::Problem)` now includes some problem statistics (#650)
