## Changelog
#### 2.19.0-beta1
* Page caching: the plugin now decides per page whether it may be cached, instead
of switching caching off for the entire site. A page that shows offer data is
only declared cacheable when this site receives webhooks and the plugin can clear
the page cache again; pages without offer data are left alone. The old “Session
cache limiter” setting is renamed “Never allow page caching (legacy)”, still
works, and can only ever make the decision stricter. It will be removed in a
following release.
* Page caching: when an offering changes, the plugin clears exactly the pages that
show it in WP Rocket, LiteSpeed Cache, W3 Total Cache, WP Super Cache, WP Fastest
Cache and Nginx Helper, and offers an action plus HTTP PURGE endpoints for anything
else. Every attempt and its result per cache is visible on Tools > Carta Online
aanbod, and a failed purge makes the plugin stop declaring offer pages cacheable
rather than serving old prices.
* Offer pages no longer set cookies. Filter selections live in the address bar
instead, so a filtered list is now linkable, bookmarkable, crawlable, and the
back button works. The previous design also meant no page cache would ever store
an offer page, and one visitor’s filter could have been served to the next.
* Detail pages: title, description and canonical link now come from the local cache,
so the head of a course page is complete even when the portal is unreachable,
and every course has its own canonical instead of all of them sharing one. Two
API calls per pageview are gone.
* SEO: three optional lines per course in Carta (`SEO_Titel`, `SEO_Omschrijving`,`
SEO_Zoekwoorden`) fill the page title, the description and the keywords. Empty
falls back to the course name and summary, cut on a word boundary. The keywords
tag is only emitted when it is actually filled; it used to contain the course
name with its spaces replaced by commas. Yoast and Rank Math get these values
through their own filters when active, instead of a second set of tags next to
theirs.
* Speed: rendering an offer list no longer calls the portal at all. Teacher lists,
contacts, accreditations, public documents, teacher names, the company list and
the portal version now come from the local cache, filled in the background. A
list with teacher and price placeholders used to cost one call per row plus one
per teacher.
* Speed: with “special pages” enabled the rewrite rules were rebuilt on every single
page view. That now happens on activation and when the setting changes.
* Correctness: a course detail page for an unknown course now answers a real 404(
or a redirect when one is configured), instead of HTTP 200 with a JavaScript
redirect that search engines read as a soft 404. A detail page without a course
in the address does the same; that case emitted broken JavaScript and did nothing
at all.
* Correctness: the internal response cache moved from files to transients, so it
works behind a load balancer and uses an object cache such as Redis when the
host provides one. This also removes a bug where a left-over lock file could
keep a cached response valid regardless of its age, which could show old data
for as long as it lasted.
* Editor: the offer list and the filter are now also available as blocks with labelled
fields, so placing them no longer requires looking up shortcode attributes. Both
render on the server, so the offerings stay visible to search engines.
* Removed `includes/co_datatable.php`. It declared a directly-callable endpoint
but blocked direct calls, so it has been unreachable for years.
* Cache schema 1.4.0: two new tables for the reads that used to happen while rendering.
Existing offerings are refreshed once in the background after the update.
* SEO: a course detail page now also carries Open Graph tags and schema.org Course
markup, both built from the local cache. A link shared on LinkedIn or WhatsApp
shows the course with its own title, description and image instead of the generic
detail page, and Google can show the course with its date, location and price.
When Yoast or Rank Math is active they keep ownership of the Open Graph tags
and receive the per-course values through their own filters.
* Tested with WordPress 7.1.
#### 2.18.3-beta7
* Cache: the retry counter for an offering is now reset at the start of every construction
round and after a successful load, instead of accumulating for the lifetime of
the offering. Previously one short API disruption used up the whole allowance
permanently, so from then on that offering got a single retry per round and was
dropped again at the first hiccup.
* Cache: an offering that fails to load moves to the back of the queue instead
of being retried immediately, so a few problematic offerings can no longer consume
the whole time budget while others wait.
* Cache: fixed an off-by-one that made the plugin give up after four attempts instead
of the configured five.
* Tools: the hydration progress on Tools > Carta Online aanbod no longer counts
abandoned offerings as completed, so the percentage reflects what is really in
the cache. Note that offerings abandoned by an older version still count as completed
until the next full construction round has run.
* Provisioning: the webhook secret is now also created when the plugin is updated
in place, not only when it is activated. WordPress does not run the activation
hook on an update, so updated sites previously ended up without a secret: every
webhook delivery was rejected and the offer cache refreshed only through the
periodic construction. Existing sites without a secret get one automatically
on the first request after this update, including an unattended overnight auto-
update.
* Provisioning: the plugin now verifies that its database tables were really created
before recording the schema version, retries every 15 minutes while they are
missing, and shows an admin notice explaining the cause. Previously a database
user without the CREATE privilege produced a silently empty offer list that was
never retried. Cache schema 1.3.2, which changes no table but makes every existing
install run this verification once so sites that are already in that state are
detected.
* Provisioning: a plugin update is refused up front when the database user cannot
create the cache tables, so the working version stays in place instead of being
replaced by one that cannot fill its cache. WordPress applies this check before
it touches any files, so nothing needs to be rolled back: the site simply keeps
running on the version it has.
* Provisioning: on sites with automatic updates enabled the plugin’s own automatic
update is now skipped while that condition lasts, instead of being attempted
and failing every night. An e-mail explains the cause and how to resolve it,
and the update proceeds by itself on the next cycle once the database privilege
is granted.
* Provisioning: the update screen, the admin notice and the notification e-mail
all explain how to recover, including the warning to overwrite the plugin rather
than delete it when going back to an earlier version. Deleting runs the uninstaller,
which removes the offering cache, the plugin settings and any claimed webhook
subscriptions.
* Settings: saving the settings no longer wipes the offer cache unless the portal
address, API key or brand changed. Changing the update frequency, rendering or
error settings now leaves the cached offerings in place, so visitors no longer
see an empty offer list while the cache is rebuilt.
* Security: API calls now validate the portal’s TLS certificate. Certificate verification
was previously switched off, which meant the API key was sent over a connection
that could be intercepted. Portals with a self-signed or expired certificate
will now be refused until the certificate is fixed.
* Uninstall: removing the plugin now also deletes the cron run history (`co_cron_run_history`)
and any left-over local-cache lock options, so every setting the plugin writes
itself is cleaned up on deletion.
#### 2.18.3-beta5
* Error handling: identical error e-mails are now throttled, so an outage (e.g.
repeated cURL timeouts) no longer floods the admin inbox with the same message.
Repeats of the same error are suppressed for 60 minutes (filter `carta_online_error_email_throttle_minutes`);
errors are still written to the log every time, and the manual “Send test e-mail”
button always sends.
#### 2.18.3-beta4
* Cache: fixed a failed schema migration that left the dynamic-items table on its
old (Identifier, Name) primary key, so multi-value dynamic items (e.g. several
Website_Capability values separated by “;”) stored only the first value. The
migration now completes and existing offers are re-hydrated so all values appear.
* Branding: fixed the offer reconciliation failing when a brand is configured.
The v2 offer filter is now sent in the exact shape the API requires, so offers
are correctly scoped to the configured brand when fetched.
* Settings: saving one settings tab (Connection / Rendering / Error handling) no
longer clears the fields of the other tabs.
* Settings: fixed duplicate admin notices (“Settings saved” / “Cache cleared”)
shown after saving.
#### 2.18.3-beta3
* Raised minimum required WordPress version to 5.3.
* Compliance: resolved Plugin Check findings (WordPress coding-standards annotations
for direct DB access on plugin-owned cache tables and a read-only nonce check).
No functional changes.
#### 2.18.3-beta2
* co-test: in test mode the shortcode now reads live from the portal entered in
the form (URL + API Key take precedence over the saved settings) instead of the
local cache.
* co-test: leaving both URL and API Key empty now falls back to the saved settings(
runs against the configured portal) instead of refusing with a validation error.
* Cache: default “local cache update frequency” is now 1440 minutes (once per day)
and is shown in the settings field when the value is missing after an upgrade.
* Tested with WordPress 7.0.
* Portal URL: a trailing slash in the portal address is now accepted and normalised,
so both `https://host` and `https://host/` work.
#### 2.18.3-beta1
* Cache: multi-value dynamic items (e.g. `Website_Capability`) are now split on`;`
into one row per value, so a `dynamic-filter` on a single value matches offerings
that list several capabilities. Schema 1.2.0 (surrogate `Id` primary key + UNIQUE(
Identifier, Name, Value)); existing cached offerings are re-hydrated automatically
on upgrade.
* Cache: `dynamic-filter` shortcode now trims the filter key/value, so a stray
space no longer breaks the match.
#### 2.18.2
* Search: `[co-offerlist search=...]` better wildcard use in URL based matching
#### 2.18.1
* Cache: dynamic-filter shortcode attribute (e.g. `dynamic-filter="DetailPagina
=/slug/"`) is honoured again. Each offering’s `payload.dynamicItems` is now flattened
into a new junction table `CartaOnline_OfferingDynamicItems` (Identifier, Name,
Value) so filters hit an indexed EXISTS clause. Schema 1.1.0 — every existing
row is automatically re-hydrated on upgrade so the new table fills without operator
action.
* Search: `[co-offerlist search=...]` works again. Search terms wrapped in literal
double quotes (the standard pattern emitted by `carta_online_get_filter_from_url()`
and the `?s=...` shortcode template) are now stripped before the SQL LIKE clause,
matching the upstream API’s behaviour.
* Renderer: `%dyn_%` placeholders are now wrapped in `…
` so themes can target individual dynamic items without
parsing the rendered string. CSS class is sanitised via `sanitize_html_class()`.
#### 2.18.0
* Admin: all plugin settings moved to a single tabbed page at Settings Carta Online,
with the tabs Connection, Rendering, Error handling, Carta Online Webhooks and
Cron tasks. The three settings tabs share one option group and the active tab
is carried through the save, so you stay on the tab you were working in.
* Admin: new Cron tasks tab showing a one-line health badge, the last executed
tasks and the scheduled tasks. Technical details (WP-Cron mode, drift, copy-paste
system-cron instructions) sit in a collapsed section that only opens automatically
when something needs attention.
* Admin: cron runs are now logged (last 50 runs, with hook name, start time, duration
and result) so a failing schedule is visible without server access.
* Admin: the legacy top-level Carta Online menu was retired; the webhook subscriptions
page now exists only as a tab on the settings page.
#### 2.17.0
* Cache: typed columns Status, DateStart, DateEnd, Location are now promoted from
the primary instance of each offering, so shortcode filters like status=Open;
AlmostFull match again
* Added Tools “Carta Online aanbod” admin page: live SyncState, searchable cache
table, payload viewer, one-click “Wipe cache and reconcile now” button
* Expertise list ([co-expertiselist]) now reads from the local cache (only fields
that actually appear in offerings) instead of /stock/fields
* Field filter is now case-insensitive so dynamic-fields cookies (lower-cased)
match the cache’s canonical casing
* Webhook subscriptions: only relevant slots (2 / 3) are listed; slot id detection
now reads `identifier` (matches Carta API), claim/release flow works end-to-end
* Webhook admin moved to Settings menu — fixes the 404 caused by hosting it as
a submenu of the existing file-path menu slug
* API Key field is now masked (type=password) on the Settings page
* Single “Secret rotated…” admin notice instead of the duplicate it used to render
* dynamicItems shortcode filter no longer throws — logged via carta_online_report_error
and ignored, so pages keep rendering
* cacheless_request now wraps array responses (e.g. /api/v1/webhook) in a {status,
result} envelope; PUT/DELETE methods supported via wp_remote_request
* Dutch translations added for every new admin string (Webhook subscriptions, Tools
page, settings field labels)
* Internal: shared `co_localcache_promote.php` helper used by both the drain (write
side) and the repository (read side) so the typed columns and the rendered cards
always agree on the primary instance
* co-offerlist template now supports generic `%dyn_%` placeholders for
every key in an offering’s dynamicItems object (T13469). Non-scalar values are
skipped.
* When the API rate limit (HTTP 429) is reached and exponential backoff is exhausted,
an admin e-mail is sent (force-routed even when general error reporting is off,
throttled to once per hour) asking to contact Carta support to raise the limit.
* Instance promotion: dateStart/dateEnd/location are now correctly drilled out
of `instances[].planning[]` (the OfferModel’s actual schedule layer) instead
of `instances[]` itself, fixing missing locations on ClassMother/ClassSingle
cards. Offerings with no scheduled planning render with empty location/date,
which is the truthful representation — no sentinel substitutes.
#### 2.16.0
* Added local DB cache: offerings are now served from a WordPress-side store, refreshed
continuously by webhooks (slot 3 / Synchronisation complete) and reconciled periodically
as a backstop
* Added Webhook subscriptions admin tab to claim / release slots and rotate the
per-install webhook secret
* Added realtime occupation overlay (js/co_realtime.js): cards stay rendered from
the cache, only the live trainee count is refreshed via a single batched admin-
ajax call
* Added 429 / 5xx exponential backoff with jitter on every API call; web context
is hard-capped at 1 s so live pages never block
* Replaced deprecated get_page_by_title() calls with WP_Query (WordPress 6.2+ compliance)
* All connection-affecting setting changes wipe the cache and trigger a fresh reconciliation;
portal/key changes also release claimed webhook slots
#### 2.15.1
* Added planning details for CourseSingle in co-offerlist shortcode with planning-
template attribute
#### 2.15.0
* Security: Fixed Stored Cross-Site Scripting (XSS) vulnerability via admin settings(
CVE-2026-1071)
