 Language Features:
- * Add support for accessors for mappings with string or byte key types
+ * Add support for getters of mappings with ``string`` or ``bytes`` key types.
  * Meta programming: Provide access to the name of contracts via ``type(C).name``.

  * Inline Assembly: Consider ``extcodehash`` as part of Constantinople.
  * Inline Assembly: Instructions unavailable to the currently configured EVM are errors now.
  * SMTChecker: Do not report underflow/overflow if they always revert. This removes false positives when using ``SafeMath``.
- * Standard JSON Interface: Allow retrieving metadata without triggering compilation.
+ * Standard JSON Interface: Allow retrieving metadata without triggering bytecode generation.
  * Static Analyzer: Warn about expressions with custom types when they have no effect.
  * Optimizer: Add new rules with constants including ``LT``, ``GT``, ``AND`` and ``BYTE``.
  * Optimizer: Add rule for shifts with constants for Constantinople.
  * Optimizer: Combine multiple shifts with constant shift-by values into one.
  * Optimizer: Do not mask with 160-bits after ``CREATE`` and ``CREATE2`` as they are guaranteed to return an address or 0.
  * Optimizer: Support shifts in the constant optimiser for Constantinople.
- * Yul Optimizer: Add rule to replace switch statements with const expr. with matching case body
+ * Yul Optimizer: Add rule to replace switch statements with literals by matching case body.

  * ABIEncoderV2: Fix invalid signature for events containing structs emitted in libraries.
  * Inline Assembly: Proper error message for missing variables.
  * Optimizer: Fix internal error related to unused tag removal across assemblies. This never generated any invalid code.

+ * SMTChecker: Fix crash related to statically-sized arrays.
  * TypeChecker: Fix internal error and disallow index access on contracts and libraries.
  * Yul: Properly detect name clashes with functions before their declaration.
