Technical Evaluation

Architecture fit

The package sits in the cache-invalidation layer of a Laravel app, bridging application events (content publish/update/delete) to an eZ Platform / Ibexa-style cache purger HTTP service.
Release 1.6 introduces a new cache purger implementation and overwrites the existing "ez cache purger service", i.e. a container binding swap inside the package's service provider. Footprint is small and confined to DI + config, which is architecturally low-coupling — but it is a correctness-critical path (stale vs. over-purged content).
Because the swap happens at the service-container level, consumers resolving the purger by interface/alias will pick up the new behavior without any code change. That is convenient and also the main risk: behavior changes can land silently.

Integration feasibility

Standard Laravel package mechanics apply (Composer install, auto-discovered service provider, publishable config). Integration effort is low for a team already running the package.
The phrase "overwrite old … service" is ambiguous: it may be a clean replacement (removal of the old binding/class) or an alias with the old service deprecated. That distinction determines whether this is a patch-level or breaking-level upgrade.

Technical risk

Behavioral change in cache invalidation with no described semantics: batching, async vs. sync, tag/URL purge strategy, retry policy, and timeout handling are all unspecified.
Backward-compatibility exposure: any app that decorates, extends, or type-hints the concrete old purger class will break if the class is removed. Fatal at boot if a binding is missing.
Config drift: no indication whether config keys, env vars, or endpoint/auth settings changed.
Over-purge / under-purge: a new purger can shift load onto origin (cache stampede) or leave stale content — both are customer-visible, neither is caught by unit tests alone.
Sparse release note: "1.6" with a one-line note is insufficient to certify semver compatibility.

Key questions (to maintainer / code diff)

Is the old ez cache purger removed or aliased/deprecated? Is the original binding name still resolvable for BC?
Are the old class's constructor signature and public methods preserved, or is there a new interface?
Did any config keys, env vars, or published config file structure change?
What does the new purger do differently — sync/async, batching, tags, Varnish vs. eZ HTTP cache, retries/timeouts?
Supported PHP / Laravel version matrix for 1.6, and is the dependency constraint widened or narrowed?
Is the new purger covered by tests, and is there a documented rollback path to 1.5?

Integration Approach

Stack fit

Assumes a Laravel application (service provider + config publish) on PHP 8.x talking to an eZ/Ibexa cache endpoint. Fits existing deployments already on this package with no new infrastructure.

Migration path

Read the 1.5→1.6 diff for the new purger class and the service provider binding change (the release note alone is not a migration guide).
Bump to ^1.6 on a branch; run composer update <vendor>/<package>; confirm no lockfile conflicts on Laravel/HTTP-client constraints.
php artisan config:clear && php artisan cache:clear after deploy — stale config caches are the most common cause of "the new purger isn't active."
Run the package test suite plus app-level smoke tests: publish, update, delete, and bulk-import a content item; verify purge requests hit the endpoint and content is served fresh.
Verify container resolution explicitly (resolve the purger and dd(get_class(...))) to confirm which implementation is bound.

Compatibility

Treat 1.6 as potentially breaking until the diff confirms otherwise, despite the minor version number.
Check whether the old concrete class is referenced anywhere in the app (decorators, mocks, custom purgers, tests). Grep for the old service name/class before upgrading.
Confirm CI matrix still passes on the app's pinned Laravel version.

Sequencing

Staging first, behind a config/feature toggle selecting old vs. new purger where feasible.
Validate invalidation correctness and purge latency under a representative content-publish volume.
Roll out to production with a pinned rollback to 1.5 and a documented revert command.
Only then remove any app-side references to the old service.

Maintenance

Small, low-churn package — but a one-line changelog means upgrade notes must be derived from source. Budget review time on every bump; do not auto-merge 1.6.
Pin to ~1.6.0 rather than a floating constraint so a 1.6.x patch cannot silently change purge behavior.

Support

No commercial support; assign an internal owner (typically the platform/backend team) accountable for cache-invalidation incidents.
Document the purger binding, endpoint config, and the rollback command in the runbook as part of this upgrade.

Scaling

Watch purge behavior under load: if the new purger batch-purges synchronously on content publish, publish latency grows with cache size and fan-out. If it is asynchronous, queue workers and retry/dead-letter handling become part of the operational surface.
Monitor origin request rate after rollout for evidence of over-purge.

Failure modes

Boot-time fatal: unresolved binding if the old service class was removed and something still references it.
Silent staleness: purge call fails and the exception is swallowed — users see outdated content with no alert.
Origin overload: aggressive purging invalidating too much, causing a cache-miss storm.
Endpoint/auth regression: changed config keys defaulting to empty, producing no-op purges.
Config cache: old cached config keeps the previous binding active post-deploy, masking the upgrade.

Ramp-up

Low for a Laravel developer comfortable with service providers and the container: roughly half a day to review the diff and validate on staging.
Medium for understanding eZ/Ibexa cache semantics (what a "purge" invalidates and its blast radius); this is the knowledge that actually de-risks the upgrade, and it should sit with the reviewer, not the deployer.
