A portable copy keeps its settings, projects and banks in a userdata folder beside the executable, so it can live on a memory stick and leaves nothing behind. An installed copy keeps them under your documents. Both are the same application, and the updater offers whichever kind you already have.

Checking a download

SHA256SUMS lists every file, and each file has a .sigstore bundle beside it, SHA256SUMS included. The signature is what proves a download came from this repository: a checksum on its own only proves the file matches whichever list you read it from.

:::sh
sha256sum -c SHA256SUMS --ignore-missing

cosign verify-blob --bundle SHA256SUMS.sigstore \
  --certificate-identity-regexp '^https://github.com/MeguminBOT/md-synth-daw/' \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com \
  SHA256SUMS

The same workflow records build provenance, which the GitHub CLI reads:

:::sh
gh attestation verify mdd-0.4.0-windows-x86_64-portable.zip --repo MeguminBOT/md-synth-daw

What changed

The song model (2)

• A clip can be given a pattern nothing else is looking at
• Edit The notes a chord leaves silent are offered a way out

Playback and export (1)

• Stream An export reserves a guess and grows into it

File formats (6)

• Audio A format chunk is read only where it is long enough to hold one
• Midi Events are read inside the track, and a length cannot run backwards
• Project A document is not trusted for an index, a length or a depth
• Vgm A log is read inside its own length, and a gzip cannot unpack without end
• Xgm A piece past thirteen minutes is written rather than exhausting memory
• Xgm A tag block that starts before the file is refused

Editors and panels (4)

• Overlay The system monitor row shows the choice it holds
• Overlay A question can be asked and one of three answers taken
• Overlay The update notice is seen rather than leaving a dark window nobody can use
• Playlist The right hand button on a clip can be given the clip's menu

The interface (6)

• Locale A language whose font is missing can still be picked
• Paint A filled polygon gets the same soft edge a rounded corner already had
• Widget The pointer says a seam can be dragged
• Widget The splitter nothing built is gone
• Widget A sheet is told when it is lowered, however that came about
• Widget A seam says it can be dragged before the pointer is on it

The application (7)

• Files Work in no file yet is asked about before anything replaces it
• Files Every look and every download writes down what it did
• Files The releases page is asked once a run rather than whenever a setting is applied
• Files An update with nothing to download is not offered
• Files A download is checked against the published hashes before it is unpacked
• Session Discord presence is described as starting at full, which it does
• Session The status bar says as much as it is asked to, and the file menu remembers

Window, audio and system (5)

• Crash A stack overflow is reported everywhere, and a fault reaches the window
• System A value two threads share survives the collector
• System The graphics memory this process holds is measured
• System A portable marker only counts where the settings can actually be written
• System What the process held at its worst, not only what it holds now

Building and packaging (7)

• The installer asks for its terms to be accepted first
• The installer lets the three CJK fonts be left out
• The three CJK faces are pinned to the file the build ships
• The installer asks where to go and says how much it takes
• The installer says what is already there and asks before replacing it
• The installer says what is already there and asks before replacing it
• MacOS aims at the macOS its libraries came from, and a vendored warning is silenced

The repository (1)

• Bump version 0.4.0

Documentation and checks (10)

### Documentation (7) - The video libraries are credited, and the badges go into rows - The readme names a minimum release for the three distributions most people run - A feature not on the page is absent rather than presumed absent - The detail behind the requirements moves to a page of its own - The graphics and storage figures carry room rather than the measured floor - The system requirements say what was measured rather than what was assumed - The warnings a build prints, and which of them were measured before being left alone ### Checks (3) - The two states a real repository puts the updater in are driven end to end - The video encoder is measured against the processors rather than taken on trust - A program that measures what the heavy paths cost on a piece built to be worse
