-- TODO: backfill 1.0.0 release notes
+## [1.0.0-incubating]
+Apache Polaris 1.0.0-incubating was released on July 9th, 2025.
+
+- **Highlights**
+ - First release ready for real-world workloads after the public beta 0.9.0
+ - **Binary distribution** – first release with single downloadable .tgz or
.zip artifact.
+ - **Helm Chart** – debut of an official Helm chart for seamless Kubernetes
deployment
+- **New features & enhancements**
+ - **Policy Store** — persistence with schema evolution, built‑in TMS
policies (Data compaction, Snapshot expiry, etc) and REST CRUD endpoints
+ - **Postgres JDBC persistence** — native JDBC backend with robust support
for concurrent changes.
+ - **Rollback Compaction on Conflicts** - makes Polaris smarter, to revert
the compaction commits in case of crunch to let the writers who are actually
adding or removing the data to the table succeed. In a sense treating
compaction as always a lower priority process.
+ - **Enhanced runtime** — new runtime powered by Quarkus delivers
out‑of‑the‑box Kubernetes readiness, quick startup, OIDC integration, and many
other benefits. Polaris server and admin tool are now using Quarkus as a
runtime framework.
+ - **HTTP caching via ETag** — the loadTable endpoint supports ETag, reducing
bandwidth and improving perceived latency
+ - **Support for external identity providers (IdP)** — Polaris can now be its
own IdP, delegate to an external IdP, or both
+ - **Snapshot filtering** – clients can choose to load only referenced
snapshots
+ - **Catalog Federation (experimental)** – federate requests to an external
Iceberg REST or Hadoop Catalog
+ - **Generic Tables (experimental)** — serve multiple table formats besides
Iceberg tables; initial Spark 3.5 plugin supports Delta Lake
+ - **Event Listener framework (experimental)** — subscribe to catalog events
(AfterTableCommitedEvent, BeforeViewCommitedEvent, etc)
+- **Notable bug fixes**
+ - **CLI and Python Client improvements** – Support for new features, CLI
repair, changes to the update subcommand, and various fixes
+ - **Safe configurations** – Catalog-level Polaris configurations follow a
strict naming convention to avoid name clashes with user-provided configuration
entries. Legacy Polaris configuration names are still supported in 1.0 to allow
existing deployments to migrate without rush.
+ - **TableOperations optimizations** – Changes to BasePolarisTableOperations
result in less traffic to object storage during commits
+ - **Bounded entity cache** – The entity cache is now more memory-aware and
less likely to lead to OOMs
+ - **Bootstrapping fixes** – Users can more easily bootstrap a new realm.
Root credentials can be provided by the user or generated by Polaris (and
returned to the user).
+- **Breaking changes**
+ - **Server Configuration** – The format used to configure the Polaris
service in 0.9 has changed with the migration to Quarkus and changes to
configurations
+ - **Bootstrap Flow** – The bootstrap flow used in 0.9 has changed with the
migration to Quarkus and the new admin tool
+
+
