+## [v1.0.14](https://github.com/TLINDEN/tablizer/tree/v1.0.14) - 2023-01-23
+
+[Full Changelog](https://github.com/TLINDEN/tablizer/compare/v1.0.13...v1.0.14)
+
+### Fixed
+
+- The -D parameter could not be used together with -a.
+
+- Fixed invalid argv handling: when the user wanted to read from stdin
+  but gave an argument which was  meant as a pattern, but also existed
+  as a filename, then tablizer opened the file, ignored stdin.
+  
+- Makefile indentation
+
+  
+### Added
+
+- added licens notes about dependencies
+
+- using hard coded uniseq version, see actions#3396457307
+
+- updated dependencies (go module versions)
+
+
+## [v1.0.13](https://github.com/TLINDEN/tablizer/tree/v1.0.13) - 2022-11-03
+
+[Full Changelog](https://github.com/TLINDEN/tablizer/compare/v1.0.12...v1.0.13)
+
+### Added
+
+- Added command line flag to generate shell completion code
+
+- Added an animated demo gif to the README to demonstrate the tool
+
+### Fixed
+
+- The `-A` flag wasn't implemented (default output mode).
+
+- Fixed building from source on systems w/o perls pod tools,
+  which is not requrired anyway since I always commit the latest
+  manpage.

+  COMPLETION
+    Shell completion for command line options can be enabled by using the
+    --completion flag. The required parameter is the name of your shell.
+    Currently supported are: bash, zsh, fish and powershell.
+
+    Detailed instructions:
+
+    Bash:
+           source <(tablizer --completion bash)
+
+        To load completions for each session, execute once:
+
+          # Linux:
+          $ tablizer --completion bash > /etc/bash_completion.d/tablizer
+
+          # macOS:
+          $ tablizer --completion bash > $(brew --prefix)/etc/bash_completion.d/tablizer
+
+    Zsh:
+        If shell completion is not already enabled in your environment, you
+        will need to enable it. You can execute the following once:
+
+          echo "autoload -U compinit; compinit" >> ~/.zshrc
+
+        To load completions for each session, execute once:
+
+          $ tablizer --completion zsh > "${fpath[1]}/_tablizer"
+
+        You will need to start a new shell for this setup to take effect.
+
+    fish:
+           tablizer --completion fish | source
+
+        To load completions for each session, execute once:
+
+           tablizer --completion fish > ~/.config/fish/completions/tablizer.fish
+
+    PowerShell:
+           tablizer --completion powershell | Out-String | Invoke-Expression
+
+        To load completions for every new session, run:
+
+           tablizer --completion powershell > tablizer.ps1
+
+        and source this file from your PowerShell profile.
