Quite to the contrary. All the bugs listed below are bugs that we have fixed. Many of these are corner cases reported by only one or perhaps a handful of our customers.

Other software companies often don't spend any effort addressing such issues, much less list them publicly.

Actions that could potentially write matches from multiple source files into the same target file failed with an access violation.

Collecting extra context after the match for a search-and-replace, search-and-delete, or rename files action with a list of search terms and "non-overlapping search" turned off could fail with an access violation.

Folding icons now scale better on high DPI systems. Starting a new action while the editor had a file open with highlighted matches could cause access violation errors. Update hyperlinks in Microsoft Office files. Triangle button that opens history menus now scales the triangle on high DPI systems.

Installer now deals with Controlled Folder Access more efficiently when Windows Defender is operational and ignores it when Windows Defender is not operational, ensuring a smoother installation on Windows 10 Fall Creators Update and April Update. Renaming files actions that produced invalid paths for one or more files failed with an access violation instead of adding a proper error message to the results that the target path is not valid.

Entering a path longer than characters into the Path box no longer causes access violation errors or crashes.

Replacement of a zero-length match at the start of a section was not written to the target file. Double-clicking a file header after a search-and-replace that modified the original files highlighted the matches that were replaced red strikeout instead of the replacements that were made green underline on the Editor panel.

Double-clicking the path of a backup file opened the target file rather than the backup copy. Installer no longer complains that it can't create the desktop shortcut if that was blocked by Controlled Folder Access.In Java, you can use FileWriter(file,true) to append new content to the end of a file..

Supported. In the context of Apache HBase, /supported/ means that HBase is designed to work in the way described, and deviation from the defined behavior or functionality should be reported as a bug. The Java FileWriter class (kaja-net.comiter) makes it possible to write characters to a that respect it works much like the FileOutputStream except that a FileOutputStream is byte based, whereas a FileWriter is character based.

The FileWriter is intended to write text, in other words. One character may correspond to one or more bytes, depending on the character encoding scheme in use.
