這次不僅是釋出，還提供了整合到 Linux Kernel 的 commit。
不過我記得在 DTrace 出來後，Linux 社群發展不少類似的工具... 不知道這次的釋出會有什麼樣的交互影響。
Vireo is a lightweight and versatile video processing library that powers our video transcoding service, deep learning recognition systems and more. It is written in C++11 and built with functional programming principles. It also optionally comes with Scala wrappers that enable us to build scalable video processing applications within our backend services.
在 Tools 的部份也可以看到很多功能，像是：
thumbnails: extracts keyframes from the input video and saves them as JPG images
viddiff: checks if two video files are functionally identical or not (does not compare data that does not affect the playback behavior)
另外要注意的是，預設不會將 GPL 的套件納入編譯，需要指定
The following libraries are disabled by default. To enable GPL licensed components, they have to be present in your system and --enable-gpl flag have to be explicitly passed to
看起來主要就是最常見的那包... (libavformat / libavcodec / libavutil / libswscale / libx264)
Apple is excited to announce that starting with CUPS 2.3 we will be providing CUPS under the terms of the Apache License, Version 2.0.
這是是韓國廠商 Hancom 在加州被告上法院：「A federal court has ruled that an open-source license is an enforceable contract」。
But after it began using Ghostscript in its software in 2013, Hancom did neither: it did not open-source its software, and it did not pay Artifex a licensing fee.
At the end of 2016, Artifex filed a lawsuit against Hancom in the US District Court for the Northern District of California.
Hancom 的理由是授權 (license) 不是合約 (contract)：
That happened when Hancom issued a motion to dismiss the case on the grounds that the company didn’t sign anything, so the license wasn’t a real contract.
而法官認定 GPL 是合約的一種：
“Not so,” said Judge Jacqueline Scott Corley in her order on the motion on April 25. Corley said the GNU GPL “provides that the Ghostscript user agrees to its terms if the user does not obtain a commercial license. Plaintiff alleges that Defendant used Ghostscript, did not obtain a commercial license, and represented publicly that its use of Ghostscript was licensed under the [GNU GPL]. These allegations sufficiently plead the existence of a contract.”
於是作者就去要 source code，並且在 Twitter 上記錄：

然後他把這份光碟的內容放上 GitHub：「All the Open Source Software provided by BMW for their i3」。
While the CDDL and GPLv2 are both "copyleft" licenses, they have different scope. The CDDL applies to all files under the CDDL, while the GPLv2 applies to derivative works.
The CDDL cannot apply to the Linux kernel because zfs.ko is a self-contained file system module -- the kernel itself is quite obviously not a derivative work of this new file system.
And zfs.ko, as a self-contained file system module, is clearly not a derivative work of the Linux kernel but rather quite obviously a derivative work of OpenZFS and OpenSolaris. Equivalent exceptions have existed for many years, for various other stand alone, self-contained, non-GPL kernel modules.
至於這種說法是不是成立，至少在還沒上法院認證前也還不知道... 不過看起來 Canonical 是頗有自信，打算將 ZFS 弄進 Ubuntu，上面有不少好用的東西...
TPP (The Trans-Pacific Partnership，跨太平洋戰略經濟夥伴關係協議) 的黑箱作業在 Wikileaks 揭露後 (TPP Treaty: Intellectual Property Rights Chapter - 5 October 2015) 才被大量解讀，而與預期的一樣，既然會黑箱當然就是見不得人，違反公眾利益的事情。
其中這組條款對原始程式碼 (source code) 的約束直接衝擊 GPL 類強制要求 open source 的約束：
Article 14.17: Source Code
No Party shall require the transfer of, or access to, source code of software owned by a person of another Party, as a condition for the import, distribution, sale or use of such software, or of products containing such software, in its territory. For the purposes of this Article, software subject to paragraph 1 is limited to mass-market software or products containing such software and does not include software used for critical infrastructure. Nothing in this Article shall preclude:
(a) the inclusion or implementation of terms and conditions related to the provision of source code in commercially negotiated contracts; or
(b) a Party from requiring the modification of source code of software necessary for that software to comply with laws or regulations which are not inconsistent with this Agreement.
This Article shall not be construed to affect requirements that relate to patent applications or granted patents, including any orders made by a judicial authority in relation to patent disputes, subject to safeguards against unauthorised disclosure under the law or practice of a Party.
In January we officially opened a public consultation (blog post) on CC BY-SA 4.0 unilateral compatibility with GPLv3, in accordance with our ShareAlike compatibility process and criteria. Following additional months of detailed analysis, discussion and deliberation with the Free Software Foundation and other stakeholders, we are very pleased to announce that we have added a declaration of one-way compatibility from CC BY-SA 4.0 to GPLv3 to our compatible licenses page!
也就是說，CC BY-SA 4.0 的素材可以放到 GPLv3 的作品裡使用並且散佈。不過要注意的是，這是 CC 的分析，而不是法院判決的結果...
