Convenience binaries can be distributed alongside source code but they are not Apache Releases -- they are just a convenience provided with no guarantee.

YES. Convenience binaries are distributed via pip (Python). R packages are published on and CRAN. Scala packages are published to Apache release repositories. They are not distributed via dist.apache.org.

RE50

YES. Release process is available describing the entire process. Each MXNet release has been performed by different release manager.

Quality

QU10

The project is open and honest about the quality of its code. Various levels of quality and maturity for various modules are natural and acceptable as long as they are clearly communicated.

YES. Website provides a security page that explains the security vulnerability reporting process.

QU40

The project puts a high priority on backwards compatibility and aims to document any incompatible changes and provide tools and documentation to help users transition to new features.

YES. Each release contains a “What’s new” on the website containing the release notes (extracted from github,  and cwiki and Jira). The project follows semantic versioning. The project takes efforts to ensure backward-compatibility for not only the software, but also the artifacts such as pre-trained models.

QU50

The project strives to respond to documented bug reports in a timely manner.

YES. Bug reports in this project are submitted via GitHub issues. The project has resolved 477 bug reports during incubation.

Community

CO10

YES. The project website has a description of the project with technical details, how to contribute, links to discussion forum and all project related information.

CO20

The community welcomes contributions from anyone who acts in good faith and in a respectful manner and adds value to the project.

YES. It’s part of the contribution guide and the current committers are really keen to welcome contributions.

CO30

Contributions include not only source code, but also documentation, constructive bug reports, constructive discussions, marketing and generally anything that adds value to the project.

YES. The project accepts a wide range of contributions and consider them merits. Documentation improvement is just as valued as code contribution. The project considers a wide variety of contributions merits towards committer/PPMC membership.

CO40

The community is meritocratic and over time aims to give more rights and responsibilities to contributors who add value to the project.

YES. The project committer group grew to 71 people, with 46 PPMC members. New committers and PPMC members are elected based on meritocracy.

CO50

The way in which contributors can be granted more rights such as commit access or decision power is clearly documented and is the same for all contributors.

CO60

The community operates based on consensus of its members (see CS10) who have decision power. Dictators, benevolent or not, are not welcome in Apache projects.

YES. The project works to build consensus. Consensus is built first through discussion. Lazy consensus is employed when applicable.

CO70

The project strives to answer user questions in a timely manner.

YES. The project typically provides detailed answers to user questions in a timely manner via dev@ mailing list, user@ mailing list, https://discuss.mxnet.io/, https://discuss.gluon.ai/ and on StackOverflow.

Consensus Building

CS10

The project maintains a public list of its contributors who have decision power -- the project's PMC (Project Management Committee) consists of those contributors.

YES. The incubator website contains the list of committers and PPMC members.

CS20

Decisions are made by consensus among PMC members [9] and are documented on the project's main communications channel. Community opinions are taken into account but the PMC has the final word if needed.

YES. The project has been making important decisions on the project dev@ mailing lists. 

CS30

Documented voting rules are used to build consensus when discussion is not sufficient. [10]

YES. The project uses the standard ASF voting rules. Voting rules are clearly stated before the voting starts for each individual vote.

CS40

In Apache projects, vetoes are only valid for code commits and are justified by a technical explanation, as per the Apache voting rules defined in CS30.

YES. The project follows the Apache voting rules. Only vetoes with technical reasons are respected.

CS50

All "important" discussions happen asynchronously in written form on the project's main communications channel. Offline, face-to-face or private discussions [11] that affect the project are also documented on that channel.

YES. The project has been making important decisions on the project mailing lists. Minor decisions may occasionally happen during code reviews, which are also asynchronous and in written form, and archived on the commits@ mailing list. Offline discussions are requested to be summarized and brought back to dev@ for further discussion. The project employs GitHub issue RFC mirroring to the dev@ list to bridge the discussions happening on GitHub and dev@.
