Thanks

感谢这十年来，所有大概三百多位开发者，对SRS所做出的贡献，包括不限于代码提交，Issue提交，问题答疑，文档完善，应用分享等等。
感谢技术委员会的核心开发者，特别感谢 TOC[60] 持续的努力。TOC都是音视频行业非常有经验的朋友，本身工作非常繁忙，业务时间贡献开源，非常不容易。
2021年6月，SRS进入 木兰开源社区[61] 孵化，感谢导师阿里云陈绪、周明辉教授、腾讯单致豪，感谢木兰社区杨丽蕴主任的大力支持。开源的各位大咖，无论在授权，还是社区治理，社区的推广上，以及社区的可持续发展上，都给与了宝贵的经验和支持。
特别感谢腾讯Tommy(李郁韬)、Eddie(薛迪)、Leo(刘连响)、Vulture(李志成)、Dragon(兰玉龙)，以及各位开发者领导对于SRS的认可和对开发者参与开源贡献的支持。正是由于各位领导的支持，各位开发者才能做出自己的贡献，为音视频整个行业的进步都做出了积极的影响。
特别感谢社区经理耿航和刘歧，对社区推广和发展做出的贡献。还有上下游开源项目的各位朋友，包括不限于FFmpeg社区、VLC社区、WebRTC社区、龙芯社区、播放器相关项目的负责人等等，SRS 5.0对接时得到了大家的很多帮助。
非常抱歉我无法列出所有给与过SRS帮助的朋友，非常感谢大家。

Next

大家千万不要以为SRS 5.0这么完善了，就没事可干了。恰恰相反，我们时间很少事情却很多，非常需要也非常欢迎大家参与。
SRS 6.0我们已经启动，如果你已经和SRS错过了10年，那现在就是一起来码代码的最好时机。
