I added a commit with my contributions. I detailed to what tasks they are related to in the commit message.

Are these numbers recent or just copy-pasted?

[emmanuelsearch]

a quick check here shows more like 425 PRs merged, and 1285 commits since the 2018.10 release (on Nov. 13th, right?)

I used the below methods, taking:

• for the merged PR count, this github API call
• for the number of commits, the below git command
  $ git rev-list --after="2018-11-13T00:00" --count master

[miri64]

912 commits is right according to

./dist/tools/release-stats/release-stats.sh 2019.01-devel 2019.01-RC3

But the rest is off a bit. The number of issues is also too small and we got 429 PRs merged

[miri64]

Sorry, just saw your comment now ^^"

The results of the release stats script were

    <tr>
        <td>2019.01-RC3</td>
        <td>7131</td>
        <td>2010903 (1914102)</td>
        <td>110 days</td>
        <td>912</td>
        <td>1554 files changed, 176241 insertions(+), 50593 deletions(-)</td>
        <td>199 Martine Lenders<br />
            128 Alexandre Abadie<br />
            112 Gunar Schorcht<br />
            48 Gaëtan Harter<br />
            48 Kees Bakker<br /></td>
    </tr>

btw. They are meant for this table. So fourth cell is the development time, fifth the number of commits, and sixth the diff stats.

Number of contributors can be counted with

$ git shortlog --no-merges -n -s "2019.01-devel".."2019.01-RC3" | wc -l
54

git rev-list --after="2018-11-13T00:00" --count master

This method also includes things that are already merged in master but not backported to the release branch. To get the number of PRs I used the PR listed in GitHub but filtered on the Milestone 2019.01. I tried to include everything I could but maybe some were missed.

The number of issues is also too small

because it only includes the issues labelled as bug.

[aabadie]

About the number of files touched and global changeset, I did:

$ git diff --shortstat 2019.01-devel..2019.01-RC3
 1525 files changed, 171769 insertions(+), 46121 deletions(-)

[aabadie]

I updated the number of days. Do we agree with the other numbers ?

[aabadie]

About git diffstats, dist/tools/release-stats/release-stats.sh uses the --no-renames option. IIUC, with this, the statistics also includes files that were just renamed. Why not, so I'll update the values.

[emmanuelsearch]

@aabadie just added a synopsis (last explicit TO DO left here ;)

[aabadie]

@emmanuelsearch, @miri64, last thing we need is a review here before the release.

[emmanuelsearch]

Please squash

[emmanuelsearch]

Assuming this paragraph is fine with everyone, I'm fine with this PR ;)

[aabadie]

Please squash

Done :)

[miri64]

@emmanuelsearch, @miri64, last thing we need is a review here before the release

Well, we also need a backport of this ;)

My comment was addressed. I'm fine with @emmanuelsearch's paragraph.

[aabadie]

@miri64, since you co-authored the release note commit, you reach the 200 commits included in this release, congrats!

[aabadie]

Let's go!

Sorry for my late review.

I think the IPv6 refactor should be also included. The project was finished during January, just before feature freeze

[aabadie]

Ok, it's not highlighted but it's added in the list of changes here. I think it's fine even if not perfect.

[jia200x]

yes, sure ;)
