-## Unreleased
+## 0.70.0
+
+This release contains a mix of features, performance improvements, and bugfixes.
+
+### Optimized read mode for OPA's in-memory store ([#7125](https://github.com/open-policy-agent/opa/pull/7125))
+
+A new optimized read mode has been added to the default in-memory store, where data written to the store is eagerly converted
+to AST values (the data format used during evaluation). This removes the time spent converting raw data values to AST
+during policy evaluation, thereby improving performance.
+
+The memory footprint of the store will increase, as processed AST values generally take up more space in memory than the
+corresponding raw data values, but overall memory usage of OPA might remain more stable over time, as pre-converted data
+is shared across evaluations and isn't recomputed for each evaluation, which can cause spikes in memory usage.
+
+This mode can be enabled for `opa run`, `opa eval`, and `opa bench` by setting the `--optimize-store-for-read-speed` flag.
+
+More information about this feature can be found [here](https://www.openpolicyagent.org/docs/v0.70.0/policy-performance/#storage-optimization).

+### Topdown and Rego
+- topdown: Use new Inter-Query Value Cache for `json.match_schema` built-in function ([#7011](https://github.com/open-policy-agent/opa/issues/7011)) authored by @anderseknert reported by @lcarva
+- ast: Fix location text attribute for multi-value rules with generated body  ([#7128](https://github.com/open-policy-agent/opa/issues/7128)) authored by @anderseknert
+- ast: Fix regression in `opa check` where a file that referenced non-provided schemas failed validation ([#7124](https://github.com/open-policy-agent/opa/pull/7124)) authored by @tjons
+- test/cases/testdata: Fix bug in test by replacing unification by explicit equality check ([#7093](https://github.com/open-policy-agent/opa/pull/7093)) authored by @matajoh
+- ast: Replace use of yaml.v2 library with yaml.v3. The earlier version would parse `yes`/`no` values as boolean. The usage of yaml.v2 in the parser was unintentional and now has been updated to yaml.v3 ([#7090](https://github.com/open-policy-agent/opa/issues/7090)) authored by @anderseknert
+
+### Runtime, Tooling, SDK
+- cmd: Make `opa check` respect `--ignore` when `--bundle` flag is set ([#7136](https://github.com/open-policy-agent/opa/issues/7136)) authored by @anderseknert
+- server/writer: Properly handle result encoding errors which earlier on failure would emit logs such as `superfluous call to WriteHeader()` while still returning `200` HTTP status code. Now, errors encoding the payload properly lead to `500` HTTP status code, without extra logs. Also use Header().Set() not Header().Add() to avoid duplicate content-type headers  ([#7114](https://github.com/open-policy-agent/opa/pull/7114)) authored by @srenatus
+- cmd: Support `file://` format for TLS key material file flags in `opa run` ([#7094](https://github.com/open-policy-agent/opa/pull/7094)) authored by @alexrohozneanu
+- plugins/rest/azure: Support managed identity for App Service / Container Apps ([#7085](https://github.com/open-policy-agent/opa/issues/7085)) reported and authored by @apc-kamezaki
+- debug: Fix step-over behaviour when exiting partial rules ([#7096](https://github.com/open-policy-agent/opa/pull/7096)) authored by @johanfylling
+- util+plugins: Fix potential memory leaks with explicit timer cancellation ([#7089](https://github.com/open-policy-agent/opa/pull/7089)) authored by @philipaconrad
+
+### Docs, Website, Ecosystem
