* Instantly update app code and images without resubmitting to TestFlight or the App Store. * Manage compatability between multiple native and JavaScript versions of your app. Download updates in the background, or while your app is executing. * Seamlessly "hot swap" updates during app use. * Require that testers and users are on the latest version of your app.

* MPW Shell - The Shell is the centerpiece of the MPW development environment. It is an integrated multiwindow text editor and command executer which supports numerous built-in commands and a powerful scripting language that allows you to customize the environment to suit your needs. The Shell also includes Projector, an integrated source code control system that simplifies the management of large, complex software projects being worked on by a team of programmers. * SC/SCpp -- C and C++ Compilers (68K) - SC and SCpp are ANSI-compliant 680x0-code-generating C and C++ compilers that are faster than previous compilers included with MPW, run in native mode on a Power Macintosh, and support the CFM-68K runtime model. * MrC/MrCpp -- C and C++ Compilers (PowerPC) - MrC and MrCpp are MPW compilers which offer greatly improved turnaround time and also generate efficient and highly-optimized PowerPC code for fastest binary execution on Power Macintosh systems. MrC adheres to the ANSI C standard (ANSI X3.159-1991) and MrCpp adheres to the ANSI C++ working paper (ANSI X3J16) except for templates and exception handling (a prerelease version of the compiler supports these two capabilities). * Assemblers (68K and PowerPC) - Two assemblers are included, one which supports the full 68xxx instruction set and the other which supports the PowerPC instruction set. The 68xxx assembler supports all the instructions and addressing modes for the MC68000, MC68010, MC68020, and MC68030 microprocessors, the MC68851 Paged Memory Management Unit (PMMU), and the MC68881 and MC68882 Floating-Point Coprocessors, in all usable combinations. * MPW Tool and Script Suite - Dozens of tools and scripts are included to assist in the development process. These include linkers, a Make tool, resource manipulation and analysis tools, file comparison utilities, and many more.
