[table=98%][tr][td][table=98%][tr][td]自从QNX慢慢失去对通用计算的兴趣开始，我已经不多关注其进展情况了（2004年前后，我一度对它非常关注）。很明显，他们已经发布了6.5 SP1。它包含优化的内存性能、更佳的网络和USB栈、改进的文件系统性能以及其他很多特性。我敢肯定在BlackBerry OS 10身上，我们能发现到它们的存在。

Since QNX - understandably - lost any and all interest in general-purpose computing, I kind of lost track where it was going (I used to have such fun with it - yup, 2004, before I even joined OSNews). Apparently, they just released version 6.5 SP1. It contains optimised memory performance, better networking and USB stacks, improved file system performance, and more. I'm sure these are all things we'll see trickle down to BlackBerry OS 10.

New service pack brings new features, higher performance to QNX Neutrino OS 6.5

If you use the QNX Neutrino OS 6.5 for your embedded projects, you owe it to yourself to check out the brand new service pack released by QNX Software Systems.

Service Pack 1 offers a number of enhancements, including:

• Optimized memory management for higher performance (improvements are particularly noticeable with the newer ARM Cortex-A8 and A9 processors)
• Updated networking stack (io-pkt) for better stability and higher performance
• Updates to security protocols, including ALTQ support for packet filtering and IKEv2 for setting up security associations
• Improvements to file systems for greater robustness and efficiency
• Updates to the USB stack, including better stack performance and stability, as well as support for the new USB classes CDC-ECM, CDC-ACM, and CDC-NCM
• 36-bit paddr support for the Freescale u-boot bootloader found in newer processors such as the P4080
