The biggest change in beta 6 is bringing it back to the Power Macintosh with a native PowerPC build, shown here running on my 1.8GHz Power Mac G4 MDD. This is built with a much later version of CodeWarrior (Pro 7.1), the same release used for Classilla and generating better optimized code than the older fat binary, and was an opportunity to simultaneously wring out various incompatibilities. Before the 68000 users howl, the 68K build is still supported!

However, beta 6 is not a fat binary — the two builds are intentionally separate. One reason is so I can use a later CodeWarrior for better code that didn't have to support 68K, but the main one is to consider different code on Power Macs which may be expensive or infeasible on 68K Macs. The primary use case for this — which may occur as soon as the next beta — is adding a built-in vendored copy of Crypto Ancienne for onboard TLS without a proxy. On all but upper-tier 68040s, setting up the TLS connection takes longer than many servers will wait, but even the lowliest Performa 6100 with a barrel-bottom 60MHz 601 can do so reasonably quickly.

The port did not go altogether smoothly. While Olivier Gutknecht's original fat binary worked fine on Power Macs, it took quite a while to get all the pieces reassembled on a later CodeWarrior with a later version of GUSI, the Mac POSIX glue layer which is a critical component (the Power Mac version uses 2.2.3, the 68K version uses 1.8.0). Some functions had changed and others were missing and had to be rewritten with later alternatives. One particularly obnoxious glitch was due to a conflict between the later GUSI's time.h and Apple Universal Interfaces' Time.h (remember, HFS+ is case-insensitive) which could not be solved by changing the search order in the project due to other conflicting headers. The simplest solution was to copy Time.h into the project and name it something else!

Another issue I've run into a couple of times is when I switch to another application (Wallops for chatting in my case) and then go back to MacLynx I'd get a white screen. It is not redrawing. I kind of have the impression this happens a lot when downloading something in the background while doing something else.
