0.12.0

• [Breaking] Improved separation between formatting and buffer management. Writer is now a base class that cannot be instantiated directly. The new MemoryWriter class implements the default buffer management with small allocations done on stack. So fmt::Writer should be replaced with fmt::MemoryWriter in variable declarations.
  Old code:

  fmt::Writer w;
  

  New code:

  fmt::MemoryWriter w;
  

  If you pass fmt::Writer by reference, you can continue to do so:

  void f(fmt::Writer &w);
  

  This doesn't affect the formatting API.

• Support for custom memory allocators (#69)

• Formatting functions now accept signed char and unsigned char strings as arguments (#73):

  auto s = format("GLSL version: {}", glGetString(GL_VERSION)); 
  

• Reduced code bloat. According to the new benchmark results, cppformat is close to printf and by the order of magnitude better than Boost Format in terms of compiled code size.

• Improved appearance of the documentation on mobile by using the Sphinx Bootstrap theme:
