Releases

Welcome to MV 2.0!

It's been almost 5 years since the last release by Naxess, and with the project now handed over to me (Greaper), this update brings a refreshed foundation for the future. This is the biggest release in MV's history — the entire app has been rebuilt from scratch, checks were updated to match the current Ranking Criteria, and a long list of new features have been added to make modding and mapping easier.

A big thank you to Hivie, Nostril, -kevincela-, and RandomeLoL for their help to make this release possible.

Built from the ground up

The entire application's frontend has been rewritten from the ground up, which allowed us to easily add new features and gain significant performance improvements!

Long gone are the days of extreme lag when searching for beatmaps or when browsing a map with many difficulties.

Checks now match the latest Ranking Criteria

All checks have been updated to match the current Ranking Criteria, which means that the issues reported by MV will now be more accurate and helpful, with significantly less false positives.

More checks

All mode-specific checks are now built directly into MV.

This includes:

• Taiko checks by Hivie
• Catch checks by Greaper
• Mania checks by RandomeLoL

You no longer need to install separate plugins for these modes.

Updated star rating system

Star rating calculations now match osu! lazer directly.

This means:

• Star rating for osu! is now up to date
• Added support for osu!taiko, osu!catch, and osu!mania SR, which means difficulty interpretation will work correctly for these modes
• Maintenance and future updates will be easier to merge

Automatic beatmap detection

Mapset Verifier can now automatically detect the beatmap you currently have open in osu! stable.

You'll see it displayed in the top-left when selecting a beatmapset:

Experimental osu! lazer support

If enabled in settings, Mapset Verifier can now detect the current beatmap you have open in osu! lazer. You'll need to open it externally from the osu! editor first.

Expanded Overview section

We have overhauled the Overview section to provide a lot more information about beatmaps:

• Metadata

  • Includes detailed information about the map's metadata
• Objects

  • Detailed analysis of the map's objects
• Beatmap

  • Contains general beatmap info
• Difficulty

  • Contains charts related to difficulty, SR, and SVs
• Audio

  • Detailed analysis of the map's audio file

Objects

This section contains detailed information about all snap usage across all difficulties, and the good old timeline comparison section, refreshed to current standards!

A dedicated hitsound timeline was also added, letting you scrub through a difficulty and see exactly what hitsounds and volume changes are used at any point in time.

Difficulty

This section contains graphs and charts related to difficulty, SR, and Slider Velocity values, now available for all modes!

You can also zoom into any specific part of the chart to see more detailed information.

Audio

You can now view detailed audio information directly inside MV — no external tools needed.

This includes:

• Audio format details (codec, sample rate, bitrate, etc.)
• A visual spectrogram to help spot unusual encoding or quality issues

Snapshots, now with full history

Snapshots let MV keep track of how a beatmapset changes over time, and this system has been reworked considerably:

• A full snapshot history is now available, showing an indication whenever there wasn't a snapshot made for a certain point in time
• Snapshots are automatically taken whenever you run checks, on top of the existing manual snapshotting, so you no longer lose track of changes between checking sessions
• The file section of a snapshot is now split up per file type, making it much easier to review changes when a mapset has multiple file types
• A quick way to open the snapshot folder was added for when you want to dig through the raw files yourself

Issue details drawer

Clicking an issue now opens a details drawer. From here you can:

• Easily copy a single issue, a whole severity group, or the entire list of issues to your clipboard
• Jump straight to any of the issue's timestamps from a quick list
• Read the check's documentation right there, so you can immediately see why something was flagged

Checks delta view

A delta view shows exactly which issues were added, resolved, or changed between check runs, making it much easier to see what actually changed since the last time you checked a mapset.

Plugins

With the 2.0 release, plugins have been updated as well, this means they need to be rebuilt to work. See the new documentation here if you need to do so.

A new plugin manager has been added to the settings page to give you more insight into the custom check plugins you have loaded.

Bookmarks

You can now bookmark beatmapsets for quick access later, instead of having to search for them again. This is an experimental feature for now.

Beta releases

We now create beta releases, this means you can have all the bleeding edge changes of MV if you can't wait for the new changes we will be making in the future. You can opt-in in the settings page under the Updates section.
