Default Permalink

Changelog

1.12.0

• Old URLs of pages (and other hierarchical post types) are now redirected (301) after the plugin converts their slug with the bulk conversion, the “Convert slug” row action or wp default-permalink convert. WordPress only does this for posts, so converted pages used to return 404. The URLs of child pages under a converted page are redirected too. Only published pages converted from 1.12.0 on are covered; the default_permalink_redirect_old_paths filter turns this off.
• Uninstalling the plugin also removes the stored old page paths.

1.11.0

• Added a “Convert slug” row action to the post, page and media lists: it converts the multi-byte slug of that one post to the selected format, without running the bulk conversion. It is shown only to users who can edit the post, and is protected by a nonce.

1.10.3

• Fixed: wp default-permalink convert --limit no longer suggests continuing with --after when no posts are left after the last processed one (only posts that failed or come before --after remain). With --dry-run, it now also shows the --after value to continue with.

1.10.2

• Fixed: the bulk conversion of a scheduled post whose time has passed no longer lets the next cron run publish it (1.10.1 kept the status but WordPress re-created the publish event). The existing schedule of a scheduled post is left unchanged.
• Fixed: the block editor no longer reports an old “slug changed” record (for example from Bulk Edit) when the slug was changed in the save being made.

1.10.1

• Fixed: with the “post date and ID” format, the slug now uses the date being saved (for example the scheduled date), not the previous date.
• Fixed: the bulk conversion (screen and WP-CLI) no longer publishes scheduled posts whose time has passed; it only changes the slug.
• Fixed: in the classic editor, a multi-byte slug typed in the permalink box is now previewed as typed (it was always saved as typed).
• Fixed: clearing the slug of a child category no longer appends the parent’s slug.
• The Site Health check no longer flags remaining multi-byte slugs as a problem (they may have been entered on purpose); it shows the count instead.
• wp default-permalink convert accepts --after=<ID> to continue a run stopped by --limit.
• Quick Edit saves no longer leave a “slug changed” record behind, and the block editor screen no longer discards it unseen.

1.10.0

• Added a Site Health check: it recommends enabling the plugin, or converting the posts that still have multi-byte slugs (WordPress 5.2 or later).
• wp default-permalink convert now accepts --post_type=<types> and --limit=<number> to convert a large site in steps.

1.9.2

• Fixed: deleting the plugin on a multisite network now removes its settings from every site, not only the current one.
• Posts created by WP-CLI, imports or cron no longer leave a “slug changed” notice record behind (nobody sees it). Use the default_permalink_record_notice filter to change this.

1.9.1

• Bulk conversion on the settings screen now continues from where the previous run stopped, so posts that cannot be converted no longer block the rest. Failed posts are reported and retried after the remaining posts.

1.9.0

• Added WP-CLI commands: wp default-permalink status and wp default-permalink convert [--dry-run].

1.8.0

• The block editor now shows the “slug changed” notice right after saving (previously it appeared the next time the edit screen was opened).
• The bulk conversion tool now previews the posts the next run converts, with their current and new slugs.

1.7.0

• Added term slug replacement: select target taxonomies (categories, tags, etc.) and new terms with a multi-byte name get a slug such as category-12. Off by default. Existing terms are not changed.
• Added the default_permalink_term_slug filter.

1.6.0

• Behavior change: posts created directly (REST API, WP-CLI, wp_insert_post(), media uploads) now get the replacement slug. Previously only posts saved from the editor were replaced.
• Behavior change: if you clear the slug of a published post and save it, the newly generated multi-byte slug is now replaced (an empty slug is treated as “not specified”). Previously the multi-byte slug was kept.
• Fixed: a multi-byte slug explicitly entered for a new post or an unsaved draft was replaced when the post was published in the same request.
• Fixed: the replacement slug was not checked for uniqueness, so it could duplicate an existing slug (e.g. a page already using “post-123”). A suffix such as “-2” is now added.
• Fixed: the “slug changed” admin notice could be recorded by a permalink preview (opening the editor) even when nothing was saved.
• The “slug changed” notice is now shown and cleared only on the post edit screen.

1.5.1

• Updated the plugin and author URLs to the new product site (https://www.redwoodcity.jp/app/default-permalink/).
• Code quality: WordPress Coding Standards compliance and Plugin Check annotations. No functional changes.

1.5

• Added an admin notice shown after a slug has been automatically replaced.
• Added a bulk conversion tool for existing multi-byte slugs. Old URLs are redirected (301) by the WordPress core old-slug mechanism.
• Hardened: slug replacement is skipped when no post ID is available (prevents colliding “post-0” slugs on direct wp_insert_post calls).

1.4

• Added slug format options: post type and ID (post-123), post date and ID (20260613-123), or a random string (a1b2c3d4).
• Added target post type selection.

1.3

• Added uninstall cleanup: plugin options are deleted when the plugin is uninstalled.
• Added a Settings link on the Plugins screen.
• Added the default_permalink_slug filter for customizing the generated slug.

1.2

• Confirmed compatibility with the latest WordPress.
• Replaced the deprecated get_page() with get_post() (fixes a fatal error on PHP 8).
• Hardened the settings page: output escaping, sanitize callback for the option, checked() helper.
• Made the settings page strings translatable and load the plugin text domain.

1.1

• Added Japanese translation.

1.0

• Initial release.
