+# DLRRuntimeSettings
+Defines a struct to configure the text recognizer runtime settings. These settings control the text recognition process.
+
+```java
+class com.dynamsoft.dlr.DLRRuntimeSettings
+```

+
+### maxThreadCount
+Sets the number of threads the algorithm will use to recognize label.
+
+```java
+int maxThreadCount
+```
+
+**Value Range**
+
+[1, 4]
+
+**Default value**
+
+4
+
+**Remarks**
+
+To keep a balance between speed and quality, the library concurrently runs four different threads by default.
+
+&nbsp;
+
+### characterModelName
+The name of the CharacterModel.
+
+```java
+String characterModelName
+```
+
+&nbsp;
+
+### referenceRegion
+Sets the reference region to search for text.
+
+```java
+DLRReferenceRegion referenceRegion
+```
+
+&nbsp;
+
+### textArea
+Sets the text area relative to the reference region.
+
+```java
+Quadrilateral textArea
+```
+
+&nbsp;
+
+### dictionaryPath
+Sets the path of the dictionary file.
+
+```java
+String dictionaryPath
+```
+
+&nbsp;
+
+### dictionaryCorrectionThreshold
+Sets the threshold of dictionary error correction.
+
+```java
+DLRDictionaryCorrectionThreshold dictionaryCorrectionThreshold
+```
+
+
+&nbsp;
+
+### binarizationModes
+Sets the mode and priority for binarization.
+
+```java
+int[] binarizationModes
+```
+
+**Value Range**
+
+Each array item can be any one of the [`EnumBinarizationMode`]({{ site.dlr_enumerations }}binarization-mode.html) Enumeration items.
+
+**Default value**
+
+`[EnumBinarizationMode.BM_LOCAL_BLOCK, EnumBinarizationMode.BM_SKIP, EnumBinarizationMode.BM_SKIP, EnumBinarizationMode.BM_SKIP, EnumBinarizationMode.BM_SKIP, EnumBinarizationMode.BM_SKIP, EnumBinarizationMode.BM_SKIP, EnumBinarizationMode.BM_SKIP]`
+
+**Remarks**
+
+The array index represents the priority of the item. The smaller index is, the higher priority is.
+
+&nbsp;
+
+### furtherModes
+Sets further modes.
+
+```java
+DLRFurtherModes furtherModes
+```

+### timeout
+
+Sets the maximum amount of time (in milliseconds) that should be spent searching for labels per page. It does not include the time taken to load/decode an image (TIFF, PNG, etc.) from disk into memory.
+
+```cpp
+int timeout
+```
+
+**Value Range**
+    [0, 0x7fffffff]
+
+**Default value**
+    10000
+
+**Remarks**
+    If you want to stop searching for labels after a certain period of time, you can use this parameter to set a timeout.

 # Release Notes - Java 2.x
 
+## 2.2.10 (06/27/2024)
+
+### Highlights
+
+{%- include release-notes/product-highlight-2.2.md -%}
+
+### Changelog
+
+#### New
+
+- Added a new property [`timeout`](../../java/api-reference/dlr-runtime-settings.md#timeout) to [`DLRRuntimeSettings`](../../java/api-reference/dlr-runtime-settings.md) class.
+- Added modes parameter `CharacterNormalizationModes` to normalize the text. The parameter is available under the following classes:
+  - `LabelRecognizerParameter`
+  - `TextArea`
+  - `LineSpecification`
+
+#### Improved
+
+- Reduced the size of MRZ model from 10MB to 2.56MB.
+- Improved single-line text confidence. This enables users to implement a result confidence filter to improve the recognition accuracy.
+- Improved character segmentation when processing some connected characters. This improves the recognition accuracy.
