We have fixed quite a few bugs and added some significant enhancements
since Apache Commons Statistics 1.2 was released,
so I would like to release Apache Commons Statistics 1.3.
Apache Commons Statistics 1.3 RC1 is available for review here:
https://dist.apache.org/repos/dist/dev/commons/statistics/1.3-RC1 (svn
revision 84131)
The Git tag commons-statistics-1.3-RC1 commit for this RC is
commons-statistics-1.3-RC1, which you can browse here:
https://gitbox.apache.org/repos/asf?p=commons-statistics.git;a=commit;h=commons-statistics-1.3-RC1
You may checkout this tag using:
git clone https://gitbox.apache.org/repos/asf/commons-statistics.git
--branch commons-statistics-1.3-RC1 commons-statistics-1.3-RC1
Maven artifacts are here:

I have tested this with 'mvn clean install' and 'mvn clean install site
site:stage -Pexamples' using:
Apache Maven 3.9.4 (dfbb324ad4a7c8fb0bf182e6d91b0ae20e3d2dd9)
Maven home: /Users/ah403/mvn/mvn
Java version: 11.0.29, vendor: Eclipse Adoptium, runtime:
/Library/Java/JavaVirtualMachines/temurin-11.jdk/Contents/Home
Default locale: en_GB, platform encoding: UTF-8
OS name: "mac os x", version: "26.3.1", arch: "aarch64", family: "mac"
Details of changes since 1.2 are in the release notes:

Site:
https://dist.apache.org/repos/dist/dev/commons/statistics/1.3-RC1/site/index.html
(note some *relative* links are broken and the 1.3 directories are not
yet created - these will be OK once the site is deployed.)

The following is intended as a helper and refresher for reviewers.
Validating a release candidate
==============================
These guidelines are NOT complete.
Requirements: Git, Java, and Maven.
You can validate a release from a release candidate (RC) tag as follows.
1a) Download and decompress the source archive from:
https://dist.apache.org/repos/dist/dev/commons/statistics/1.3-RC1/source
1b) Check out the RC tag from git (optional)
This is optional, as a reviewer must at least check source distributions.
git clone https://gitbox.apache.org/repos/asf/commons-statistics.git
--branch commons-statistics-1.3-RC1 commons-statistics-1.3-RC1
cd commons-statistics-1.3-RC1
2) Check Apache licenses
This step is not required if the site includes a RAT report page, which you
then must check.
This check should be included in the default Maven build, but you can check
it with:
mvn apache-rat:check
3) Check binary compatibility
This step is not required if the site includes a JApiCmp report page, which
you then must check.
This check should be included in the default Maven build, but you can check
it with:
mvn verify -DskipTests -P japicmp japicmp:cmp
4) Build the package
This check should be included in the default Maven build, but you can check
it with:
mvn -V clean package
You can record the Maven and Java version produced by -V in your VOTE reply.
To gather OS information from a command line:
Windows: ver
Linux: uname -a
4b) Check reproducibility
To check that a build is reproducible, run:
mvn clean verify artifact:compare -DskipTests -Dreference.repo=
https://repository.apache.org/content/repositories/staging/
'-Dbuildinfo.ignore=*/*.spdx.json'
Note that this excludes SPDX files from the check.
5) Build the site for a multi-module project
mvn site
mvn site:stage
Check the site reports in:
- Windows: target\site\index.html
- Linux: target/site/index.html
Note that the project reports are created for each module.
Modules can be accessed using the 'Project Modules' link under
the 'Project Information' menu (see <path-to-site>/modules.html).
