+## 15.1.0 (2018-03-29)
+
+Features:
+  - It is now possible to use opaque handles even when the OEMCrypto integration
+    is L3, assuming the OEMCrypto integration is able to use opaque handles.
+    Previously, the CE CDM blocked this combination of features.
+  - Methods for querying information about the underlying OEMCrypto integration
+    have been added to the CE CDM API.
+    - `Cdm::getRobustnessLevel()`
+    - `Cdm::getResourceRatingTier()`
+    - `Cdm::getOemCryptoBuildInfo()`
+  - Several new errors have been added to the CE CDM API. These errors are
+    considered "recoverable errors" because there are well-known actions the
+    caller can take to recover from them. These responses are covered in the
+    [Integration Guide][integration-guide-15.1].
+    - `kResourceContention`
+    - `kSessionStateLost`
+    - `kSystemStateLost`
+    - `kOutputTooLarge`
+  - Improved error reporting around entitlement licenses.
+
+Documentation:
+  - The Integration Guide that shipped with CE CDM 15.0.0 did not contain
+    updates about the removal of `onDirectIndividualizationRequest()` and did
+    not contain documentation for the manual provisioning flow that replaced it.
+    The [Integration Guide for CE CDM 15.1.0][integration-guide-15.1] has been
+    updated to correct this.
+  - Additional comments have been added to the OEMCrypto unit tests to help
+    integration partners better understand what is going wrong when they get an
+    error. Future releases will further expand on this.
+  - [Widevine_OEMCrypto_Version_Compatibility.pdf][oec-version-compat] has been
+    updated to document the number of required keys per session in each version.

+
+Bugfixes:
+  - This release fixes a bug that caused CE CDM initialization to fail when
+    using opaque handles.
+  - The usage table unit tests have been re-enabled. Several additional tests
+    for new scenarios have been added.
+  - Several failures affecting edge cases when deleting usage table entries have
+    been fixed.
+  - The playback duration was not being counted correctly in cases where the
+    license had an unlimited license duration but a very short playback duration
+    and the license was received after playback had already started. This has
+    been fixed.
+  - The default compiler warnings for the sample "x86-64" platform have been
+    strengthened, while some warnings that are triggered by third-party
+    libraries have been disabled for only those libraries.
+  - Several benign problems that triggered strict compiler warning levels have
+    been fixed.
+  - An error with the kSilent log level that could occur with very strict
+    compiler or sanitizer settings has been fixed.
+  - Fixed a spurious error that could occur when querying the SRM version on
+    devices without SRM support.
+  - Reworded some code that was tripping up the MSVC compiler.
