-## 2.1.0
-
-### New Features
-
-* Added a new predicate `DataFlow::getARuntimeTarget` for getting a function that may be invoked by a `Call` expression. Unlike `Call.getTarget` this new predicate may also resolve function pointers.
-* Added the predicate `mayBeFromImplicitlyDeclaredFunction()` to the `Call` class to represent calls that may be the return value of an implicitly declared C function.
-* Added the predicate `getAnExplicitDeclarationEntry()` to the `Function` class to get a `FunctionDeclarationEntry` that is not implicit.
-* Added classes `RequiresExpr`, `SimpleRequirementExpr`, `TypeRequirementExpr`, `CompoundRequirementExpr`, and `NestedRequirementExpr` to represent C++20 requires expressions and the simple, type, compound, and nested requirements that can occur in `requires` expressions.
-
-### Minor Analysis Improvements
-
-* The function call target resolution algorithm has been improved to resolve more calls through function pointers. As a result, dataflow queries may have more results.
-
-## 2.0.2
-
-### Minor Analysis Improvements
-
-* Added taint flow model for `fopen` and related functions.
-* The `SimpleRangeAnalysis` library (`semmle.code.cpp.rangeanalysis.SimpleRangeAnalysis`) now generates more precise ranges for calls to `fgetc` and `getc`.
-
-## 2.0.1

- *
- * Anatomy of a printed IR instruction
- *
- * An instruction:
- *
- * ```
- * # 2281|     v2281_19(void) = Call[~String]     : func:r2281_18, this:r2281_17
- * ```
- *
- * The prefix `# 2281|` specifies that this instruction was generated by the C++ source code on line 2281.
- * Scrolling up in the printed output, one will eventually find the name of the file to which the line
- * belongs.
- *
- * `v2281_19(void)` is the result of the instruction. Here, `v` means this is a void result or operand (so
- * there should be no later uses of the result; see below for other possible values). The `2281_19` is a
- * unique ID for the result. This is usually just the line number plus a small integer suffix to make it
- * unique within the function. The type of the result is `void`. In this case, it is `void`, because
- * `~String` returns `void`. The type of the result is usually just the name of the appropriate C++ type,
- * but it will sometimes be a type like `glval<int>`, which means result holds a glvalue, which at the
- * IR level works like a pointer. In other words, in the source code the type was `int`, but it is really
- * more like an `int*`. We see this, for example, in `x = y;`, where `x` is a glvalue.
- *
- * `Call` is the opcode of the instruction. Common opcodes include:
- *
- * * Arithmetic operations: `Add`, `Sub`, `Mul`, etc.
- * * Memory access operations: `Load`, `Store`.
- * * Function calls: `Call`.
- * * Literals: `Constant`.
- * * Variable addresses: `VariableAddress`.
- * * Function entry points: `EnterFunction`.
- * * Return from a function: `Return`, `ReturnVoid`. Note that the value being returned is set separately by a
- *   `Store` to a special `#return` variable.
- * * Stack unwinding for C++ function that throw and where the exception escapes the function: `Unwind`.
- * * Common exit point for `Unwind` and `Return`: `ExitFunction`.
- * * SSA-related opcodes: `Phi`, `Chi`.
- *
- * `[~String]` denotes additional information. The information might be present earlier in the IR, as is the case
- * for `Call`, where it is the name of the called function. This is also the case for `Load` and `Store`, where it
- * is the name of the variable that loaded or stored (if known). In the case of `Constant`, `FieldAddress`, and
- * `VariableAddress`, the information between brackets does not occur earlier.
- *
- * `func:r2281_18` and `this:r28281_17` are the operands of the instruction. The `func:` prefix denotes the operand
- * that holds the address of the called function. The `this:` prefix denotes the argument to the special `this`
- * parameter of an instance member function. `r2281_18`, `r2281_17` are the unique IDs of the operands. Each of these
- * matches the ID of a previously seen result, showing where that value came from. The `r` means that these are
- * "register" operands (see below).
- *
- * Result and operand kinds:
- *
- * Every result and operand is one of these three kinds:
- *
- * * `r` "register". These operands are not stored in any particular memory location. We can think of them as
- *   temporary values created during the evaluation of an expression. A register operand almost always has one
- *   use, often in the same block as its definition.
- * *  `m` "memory". These operands represents accesses to a specific memory location. The location could be a
- *    local variable, a global variable, a field of an object, an element of an array, or any memory that we happen
- *    to have a pointer to. These only occur as the result of a `Store`, the source operand of a `Load` or on the
- *    SSA instructions (`Phi`, `Chi`).
- * * `v` "void". Really just a register operand, but we mark register operands of type void with this special prefix
- *   so we know that there is no actual value there.
- *
- * Branches in the IR:
- *
- * The IR is divided into basic blocks. At the end of each block, there are one or more edges showing the possible
- * control flow successors of the block.
- *
- * ```
- * #   44|     v44_3(void)    = ConditionalBranch : r44_2
- * #-----|   False -> Block 4
- * #-----|   True -> Block 3
- * ```
- * Here we have a block that ends with a conditional branch. The two edges show where the control flows to depending
- * on whether the condition is true or false.
- *
- * SSA instructions:
- *
- * We use `Phi` instructions in SSA to create a single definition for a variable that might be assigned on multiple
- * control flow paths. The `Phi` instruction merges the potential values of that variable from each predecessor edge,
- * and the resulting definition is then used wherever that variable is accessed later on.
- *
- * When dealing with aliased memory, we use the `Chi` instruction to create a single definition for memory that might
- * or might not have been updated by a store, depending on the actual address that was written to. For example, take:
- *
- * ```cpp
- * int x = 5;
- * int y = 7;
- * int* p = condition ? &x : &y;
- * *p = 6;
- * return x;
- * ```
- *
- * At the point where we store to `*p`, we do not know whether `p` points to `x` or `y`. Thus, we do not know whether
- * `return x;` is going to return the value that `x` was originally initialized to (5), or whether it will return 6,
- *  because it was overwritten by `*p = 6;`. We insert a `Chi` instruction immediately after the store to `*p`:
- *
- * ```
- * r2(int)     = Constant[6]
- * r3(int*)    = <<value of p>>
- * m4(int)     = Store           : &r3, r2  // Stores the constant 6 to *p
- * m5(unknown) = Chi             : total:m1, partial:m4
- * ```
- * The `partial:` operand represents the memory that was just stored. The `total:` operand represents the previous
- * contents of all of the memory that `p` might have pointed to (in this case, both `x` and `y`). The result of the
- * `Chi` represents the new contents of whatever memory the `total:` operand referred to. We usually do not know exactly
- * which parts of that memory were overwritten, but it does model that any of that memory could have been modified, so
- * that later instructions do not assume that the memory was unchanged.

- * and the resulting definition is then used wherever that variable is accessed later on.
- *
- * When dealing with aliased memory, we use the `Chi` instruction to create a single definition for memory that might
- * or might not have been updated by a store, depending on the actual address that was written to. For example, take:
- *
- * ```cpp
- * int x = 5;
- * int y = 7;
- * int* p = condition ? &x : &y;
- * *p = 6;
- * return x;
- * ```
- *
- * At the point where we store to `*p`, we do not know whether `p` points to `x` or `y`. Thus, we do not know whether
- * `return x;` is going to return the value that `x` was originally initialized to (5), or whether it will return 6,
- *  because it was overwritten by `*p = 6;`. We insert a `Chi` instruction immediately after the store to `*p`:
- *
- * ```
- * r2(int)     = Constant[6]
- * r3(int*)    = <<value of p>>
- * m4(int)     = Store           : &r3, r2  // Stores the constant 6 to *p
- * m5(unknown) = Chi             : total:m1, partial:m4
- * ```
- * The `partial:` operand represents the memory that was just stored. The `total:` operand represents the previous
- * contents of all of the memory that `p` might have pointed to (in this case, both `x` and `y`). The result of the
- * `Chi` represents the new contents of whatever memory the `total:` operand referred to. We usually do not know exactly
- * which parts of that memory were overwritten, but it does model that any of that memory could have been modified, so
- * that later instructions do not assume that the memory was unchanged.
