Due to various improved compile time code optimizations executable code generated by GCC 3.1 tends to be about 6 percent faster on average than code generated by the 2.95 branch. GCC 3.1 also features a much faster preprocessor which makes compiling faster if you are a developer. A few Obj-C improvements include things like fixed linker warnings, certain @protocal definitions will work properly, and perhaps the largest improvement: the classlookup code in the runtime library has been rewritten providing faster performance. There are some caveats to this as some things that will compile in 2.95x have a few more problems with 3.1. Also, previously compiled libraries (or programs even, perhaps) already installed on your system might have to be recompiled if you upgrade to Jaguar. >> As a developer I'm quite happy to >> have paid for the new updated tools to be so deeply integrated.

I am unsure how the developer tools are more deeply integrated in Jaguar than in previous versions however. Les Harris
