Note: Please note that the following reflects changes for a future release of MythTV. The current release is 34.0.
Note: This page is actively updated, edited, and modified during the current trunk development cycle (expected to become the "0.25" release). Expect it to change drastically, on a frequent basis, up until the next official release. Items may be added, changed, and removed to accurately reflect anticipated functionality and features leading up to the release date.
Below is an overview of the changes currently in trunk, which will become a future release of MythTV. Some of these changes, most notably the fixes, may have been backported to the 0.24-fixes branch. This is a fairly comprehensive list of significant or noticeable changes that impact the user experience in some way. For every change listed on this changelog, there are many times more changes not listed related to the core framework and inner workings of the software which allow MythTV to do what it does - in other words, what is listed is just the tip of the iceberg.
