15399	mlt-7.0.1	Bruce Dubbs	blfs-book	"New major version.  Required for kdenlive.

Version 7.0.1

This version is just build fixes for the most immediate problems with the
somewhat new but exclusive build system in v7.

* Fixed docker image not working.
* Fixed a system-installed build cannot finds its modules and data.
* Fixed the python installation path for binaries.
* Added support for the `DESTDIR` environment variable when creating melt symlink.
* Increased the build constant for the maximum size of a line of a properties file.
* Fixed the vid.stab metadata install path.

Version 7.0.0

This is a major new version that breaks API to add a major new feature to the
framework: retiming. This is accomplished through new classes `mlt_chain` and
`mlt_link`. And since we are breaking API we decided to clean house by
removing deprecations and switching the build system over entirely to CMake.
For more information see our
[migration guide](https://mltframework.org/docs/v7migration/).

Framework

  * Renamed `mlt_image_rgb24a` as `mlt_image_rgba`.
  * Renamed `mlt_image_rgb24` to `mlt_image_rgb`.
  * Renamed `mlt_image_glsl` to `mlt_image_movit`.
