CHANGELOG.md stops at an unreleased "Version 0.14.0" entry, but the latest tag is v2.0.0, Hedgehog 2.0.4 is on NuGet and master has more. This adds the missing versions, 1.0.0 to 2.0.4, and an Unreleased section, in the existing format. Only CHANGELOG.md changes.

CONTRIBUTING.md says that merged PRs go into the changelog; the file was last touched in July 2023.

What is in it

• Every one of the 45 pull requests merged since 0.13.0 is listed, with its author. Stateful testing #471 and Remove Hedgehog.Stateful #477 are listed twice, because each of them has two separate changes.
• Changes that were pushed without a pull request are linked by commit: the exception unwrapping of 1.0.2, the Copilot chatmode of 2.0.1 and two small commits of Hedgehog.Stateful.
• Hedgehog.Xunit.v3 followed the versions of Hedgehog up to 2.0.0, so it has no sections of its own. Hedgehog.NUnit and Hedgehog.MSTest are mentioned where they appear. Hedgehog.Stateful was released from this repository (0.5.0-beta1 to 0.7.0-beta3) until Remove Hedgehog.Stateful #477 removed it, so its changes are under 2.0.1 and 2.0.2.
• 1.0.0 has the highlights of the GitHub release, and the pre-releases 1.0.0-beta1 to 1.0.0-rc1 are folded into it.
• "Version 0.14.0" was never released. Its entries (Targeted only netstandard2.0 in Hedgehog.fsproj #417, Speed up recheck #433, Fix dead end message #436, Efficient falseToFailure #437) are in the notes of the v1.0.0 release, so they moved to 1.0.0 with the same text.
• The references [437] and [LyndonGingerich] were not defined (the second one lacked the colon), so those links did not work.

What to check

• The dates. They are the dates of the GitHub releases, or the NuGet publish dates (UTC) for the versions that have no release (1.0.2, 2.0.1 to 2.0.4). 2.0.0 is 2025-12-08 as in its release, although NuGet had it at 2025-12-07 23:46 UTC. 2.0.3 is 2026-01-13, although its commit is dated 2026-01-14 in +11:00.
• The wording of the entries. It follows the descriptions of the pull requests and the diffs between the version bumps, not only the titles. In particular, please look at the breaking changes that I marked (Merge autogen #454, Tagged journal #470, Adds parameter for DateTimeKind #480).
• Unreleased lists what is on master, but not in the latest versions on NuGet: Hedgehog 2.0.4, Hedgehog.Xunit.v3 2.0.0 and Hedgehog.NUnit 1.0.0. Hedgehog.MSTest 1.0.0 is already published.

Happy to change the format, for example to sections per package.

@xperiandri, thank you for the PR! Copilot had some suggestions, I included them. Indeed, the CHANGELOG was not up to date and now that we have so many agentic tools in our disposals (vs back then when the project was created) perhaps we can automate this process.

[xperiandri]

@moodmosaic we can port an approach from https://github.com/fsprojects/FSharp.Control.R3 which I took from some F# OSS library template

[moodmosaic]

@xperiandri, sure! Can you provide here the link from the PR in https://github.com/fsprojects/FSharp.Control.R3 that enables this to see?
