+
+**Describe the bug**
+A clear and concise description of what the bug is.
+
+**Version information**
+1. The version of the TwelveMonkeys ImageIO library in use.
+For example:  4.0.0
+
+2. The *exact* output of `java --version` (or `java -version` for older Java releases). 
+For example: 
+
+    java version "1.8.0_271"
+    Java(TM) SE Runtime Environment (build 1.8.0_271-b09)
+    Java HotSpot(TM) 64-Bit Server VM (build 25.271-b09, mixed mode)
+
+3. Extra information about OS version, server version, standalone program or web application packaging, executable wrapper, etc. Please state exact version numbers where applicable.
+
+**To Reproduce**
+Steps to reproduce the behavior:
+
+1. Compile the below sample code
+2. Download the sample image file
+3. Run the code with the sample file
+4. See error
+
+**Expected behavior**
+A clear and concise description of what you expected to happen.
+
+**Example code**
+Preferably as a failing JUnit test, or a standalone program with a `main` method that showcases the problem. 
+
+Less is more. Don't add your entire project, only the code required to reproduce the problem. 😀 
+
+**Sample file(s)**
+Attach any sample files needed to reproduce the problem. Use a ZIP-file if the format is not directly supported by GitHub.
+
+**Stak trace**
+Always include the stack trace you experience.
+
+**Screenshots**
+If applicable, add screenshots to help explain your problem.
+Do not add screenshots of code or stack traces. 😀 
+
+**Additional context**
+Add any other context about the problem here.

+
+General programming issues and problems will reach a much wider audience at StackOverflow, we suggest you ask them there. This will offload our work with maintaining the library, and make sure you get better help sooner.
+
+Tag the question with `javax-imageio` and/or `twelvemonkeys` and we'll find them there.

+**What is fixed** Add link to the issue this PR fixes. 
+
+Example: Fixes #42. 
+
+**Why is this change proposed** If this change does *not* fix an open issue, briefly describe the rationale for this PR.
+
+**What is changed** Briefly describe the changes proposed in this pull request: 
+
+* Fixed rare exception happening in `x >= 42` case
+* Small optimization of `decompress()` method
+* Corrected API doc for `compress()` method to reflect current implementation
