Changelog

Sourced from Documenter's changelog.

Version [v1.16.1] - 2025-11-21

Fixed

• The -g is now passed to curl when checking links, to disable globbing, which could cause undesirable behavior when checking links containing characters like for example [, {, & or ?. (#2839, #2842)
• Fixed insufficient paragraph spacing in HTML output for @docs blocks. ([#2845, #2847])
• Don't expand details admonition by default. ([#2846, #2847])
• Removed superfluous vertical space at end of @docs blocks. (#2849)

Version [v1.16.0] - 2025-11-14

Added

• Added option treat_markdown_warnings_as_error which throws an error when encountering a markdown/interpolation warning (#2792, #2751)
• Footnotes can now be previewed by hovering over the link. (#2080)
• The version selector now attempts to stay on the same page when switching between documentation versions. If the page doesn't exist in the target version, it falls back to the version homepage. (#2801)
• Allow named @eval blocks: such a block shares its execution context with all other @eval, @example, @repl and @setup blocks on the same page which use the same name. (#2074, #2812)

Changed

• Page category is removed from the search index and now everything is in section category. (#2762, #2413)
• Changed the docstring block accordions from a custom implementation to HTML details+summary tag. (#2772, #2773)
• Improved the search tokenizer and custom trimmer to improve search results. (#1457, #2114, #2744)
• Improved several warning/error messages to (more accurately) report the location (filename, line range) in which the warning/error originated. (#2426, #2752, #2793, #2803, #2809)
• Warn/error if jldoctest starts with an empty line; or lacks empty line between two REPL prompts. (#2031, #2083, #2679, #2808)
• The forcepush=true option to deploydocs now uses --force-with-lease instead of --force. (#2817)
• Improved the generation of anchors for admonitions in HTML output to be more stable and e.g. not change due to changes of the internal representation across different Julia versions. (#2710)

Fixed

• Modules for @example environments are now generated by eval'ing an expression, rather than invoking the Module constructor, which is not recommended. (#2683)

• Fix handling of expandfirst entries containing slashes as path separators on Windows. (#1725, #2804)

• Changed the header crossref step to eagerly fail when encountering a non-unique header slug. (#2668, #2787)

  This is potentially breaking and may cause some documentation builds to fail. Those previously passed but generated incorrect cross-references. You can fix this by ensuring that you have distinct headers across your markdown pages, or by using the @id syntax to give the headers unique slugs.

• Changed CSS for the navigation "breadcrumbs" at the top of each page to avoid an issue where code blocks in there were missing spacing around them. (#1614, #2813)

• Commit status for pull request previews publishing in GitHub Actions for out-of-repo deployment now works correctly. (#2814, #2816)

• Fix assertions resp. errors being raised in @example, @eval, @repl blocks that are empty or contain code with syntax errors. (#2206, #2731, #2827)

Version [v1.15.0] - 2025-10-22

Changed

• Created a warning for when the search index size is too big (500Kib). (#2423, #2753)
• In the HTML output, the search modal can now be navigated using up and down keys. (#2761)

CI Failure Analysis

The CI failure is caused by an accidental downgrade of GitHub Actions versions in the workflow file:

• actions/checkout was downgraded from v6 to v4
• julia-actions/setup-julia was downgraded from v2 to v1

This appears to be a merge conflict or rebase issue during the Dependabot update process.

Fix Required

The .github/workflows/CI.yml file needs to be restored to use the correct versions:

- uses: actions/checkout@v4
- uses: julia-actions/setup-julia@v1
+ uses: actions/checkout@v6
+ uses: julia-actions/setup-julia@v2

The Documenter update itself (to v1.16.1) is fine and should not cause any issues based on the changelog - it contains only bug fixes and minor improvements.

Recommendation

@dependabot rebase

This should regenerate the PR with the correct workflow file versions while keeping the Documenter update.

Update: Rebase Complete but Issue Persists

The rebase completed, but Dependabot is still downgrading the GitHub Actions versions in the workflow file. This appears to be a systematic issue with Dependabot's configuration.

Two Options to Fix This

Option 1: Manual Fix (Recommended)

Someone with write access can manually fix the workflow file and push to this branch:

gh pr checkout 44
# Edit .github/workflows/CI.yml to restore v6 and v2
git add .github/workflows/CI.yml
git commit -m "Fix workflow file versions"
git push

The required changes:

- uses: actions/checkout@v4
- uses: julia-actions/setup-julia@v1
+ uses: actions/checkout@v6
+ uses: julia-actions/setup-julia@v2

Option 2: Close and Recreate

Close this PR and manually update the Documenter version in docs/Project.toml:

[compat]
Documenter = "1.16.1"

Why This Matters

The Documenter v1.16.1 update itself is fine (only bug fixes). However, downgrading the GitHub Actions may cause compatibility issues or miss important security/feature updates.
