New features

• Press ctrl-g to "jump to definition" and ctrl-t to jump back. If there is nowhere to jump, ctrl-g and ctrl-t will toggle the status bar or record a macro, respectively, as before. This has only been tested on Go source code, and is an experimental feature.

Performance improvements

• Revert back to use os.ReadFile instead of the custom implementation that did not call os.Stat (as os.ReadFile does). The performance improvements for the custom way of reading files only applied to some filesystems and setups (XFS + NVMe).

Changes to the VTE/GUI application

This release has been compiled with Go 1.20.6.

• Improve the performance when reading files that are of a typical size for source code and Markdown documents, by using a 1024 byte buffer and also avoiding calling os.Stat. Related graph, where the X-axis is for approximately how large the files that are being read are (take1024 is the one that uses 1024-byte buffers when reading):

Various

• Avoid saving some filenames in /tmp and also - to the location history.
• Minor changes to how commemorative images for new highscores from the little included easter-egg game are saved.
• Update dependencies.
