Apa itu Changelog ?

Changelog adalah sebuah ringkasan perubahan yang disusun secara sistematis melalui proses dikurasi(dipilah), secara kronologis memerintahkan data daru catatan perubahan pada setiap versi sebuah rancangan.

Kenapa diperlukan Changelog ?

Changelog dibutuhkan untuk mempermudah user/admin atau pengguna/admin untuk berkontribusi aktif dalam memantau dan menyusun sebuah ringkasan secara presisi/tepat/spesifik/sistematis dan juga sebagai pembanding versi sehingga dapat melanjutkan ke tahap pengembangan sebuah rancangan yang ingin dibuat.

Siapa yang memerlukan Changelog ?

Semua orang pada bidang pengembangan memerlukan sebuah changelog, baik konsumen maupun developer. Pada sebuah software diperlukan pembaharuan dan setiap pembaharuan, pengguna dapat melihat beberapa aspek perubahan yang mengakibatkan sebuah pertayaan kenapa dan bagaiman software tersebut diperbaharui.

Bagaimana cara membuat changelog yang benar?


Prinsip Kerja

  • Changelogs diperlukan untuk Manusia, bukan mesin.
  • Terdapat sebuah masukan pada setiap versi tunggal.
  • Perubahan yang bersifat sama pada sebuah tipe harus dikelompokkan.
  • Versi dan Sesi harus saling terhubung dan terkait.
  • Veri terbaru harus ditampilkan di awal.
  • Waktu rilis setiap versi harus spesifik.
  • Apakah anda telah mengikuti Semantic Versioning. ?


Tipe Perubahan

  • Added berfungsi untuk penambahan fitur baru.
  • Changedberfungsi sebagai perubahan fitur yang telah ada secara fungsional.
  • Deprecated berfungsi sebagai fitur-yang-akan-dihapus.
  • Removed berfungsi sebagai fitur yang telah dihapus.
  • Fixed berfungsi sebagai kesalahan-keselahan yang telah dibenahi.
  • Security berfungsi sebagai kasus kerentanan keamanan.

Bagaimana cara mengoptimalkan changelog agar dapat diperbaharui secara efisien?

Keep an Unreleased section at the top to track upcoming changes.

This serves two purposes:

  • People can see what changes they might expect in upcoming releases
  • At release time, you can move the Unreleased section changes into a new release version section.

Can changelogs be bad?

Yes. Here are a few ways they can be less than useful.

Commit log diffs

Using commit log diffs as changelogs is a bad idea: they’re full of noise. Things like merge commits, commits with obscure titles, documentation changes, etc.

The purpose of a commit is to document a step in the evolution of the source code. Some projects clean up commits, some don’t.

The purpose of a changelog entry is to document the noteworthy difference, often across multiple commits, to communicate them clearly to end users.

Ignoring Deprecations

When people upgrade from one version to another, it should be painfully clear when something will break. It should be possible to upgrade to a version that lists deprecations, remove what’s deprecated, then upgrade to the version where the deprecations become removals.

If you do nothing else, list deprecations, removals, and any breaking changes in your changelog.

Confusing Dates

Regional date formats vary throughout the world and it’s often difficult to find a human-friendly date format that feels intuitive to everyone. The advantage of dates formatted like 2017-07-17 is that they follow the order of largest to smallest units: year, month, and day. This format also doesn’t overlap in ambiguous ways with other date formats, unlike some regional formats that switch the position of month and day numbers. These reasons, and the fact this date format is an ISO standard, are why it is the recommended date format for changelog entries.

Frequently Asked Questions

Is there a standard changelog format?

What should the changelog file be named?

What about GitHub Releases?

Can changelogs be automatically parsed?

What about yanked releases?

Should you ever rewrite a changelog?

How can I contribute?


I went on The Changelog podcast to talk about why maintainers and contributors should care about changelogs, and also about the motivations behind this project.
