What's new across freemkv — the command line, the desktop app, and the
autorip service — newest first. Every release ships all three together under
one version number.
For the full technical detail behind a release, see the per-component notes:
[freemkv releases](https://github.com/freemkv/freemkv/releases) ·
[autorip releases](https://github.com/freemkv/autorip/releases).
## 1.7.7
2026-09-26
### Fixed
- Forced PGS subtitles now disappear when their display period ends, instead of remaining until the next subtitle.
- Preserve PGS clear-event timestamps when remuxing, addressing the reproduced issue in #52. A fresh rip is needed to confirm the fix on affected discs.
- Improve audio frame handling and preserve opening audio and MKV timing metadata.
- Keep the Linux desktop interface responsive while opening and scanning sources.
### Linux packages
- Add a native `.deb` containing the desktop app and CLI for Ubuntu 24.04 and Linux Mint 22.
- Publish direct `.flatpak` downloads on GitHub Releases, independently of Flathub acceptance.
- Add installation instructions and download links for both formats.
### Quality and maintenance
- Expand subtitle regression tests and add FFmpeg checks for subtitle clearing, audio/video content and timing.
- Add media known-answer tests and Linux/macOS/Windows output comparisons.
## 1.7.6
2026-09-26
**Added**
- **Linux desktop app (BETA).** freemkv now has a native GTK4 + libadwaita
desktop app on Linux, with the same features as the macOS and Windows apps:
pick a drive, file or folder, tick titles and tracks, choose a format, press
Rip. Same core on all three, so a fix lands everywhere at once. A Flatpak
(`org.freemkv.FreeMKV`) and an AppImage are on the way; Flathub submission
follows this release.
- **Rip-finished notification** on macOS, Windows and Linux. Click it to open
the output folder. Turn it off in Settings if you don't want it (default: on).
**Fixed**
- `freemkv info` accepts `--log-level`, and `--log-file` without a path no
longer eats the next option.
- No more false "MP4 can't hold MPEG-2" warning after switching discs.
- The log pane stays fast during long rips on macOS and Windows.
- On Linux the default output folder is your real Videos folder, even if it
was moved or has a translated name.
- `info --share` explains why the disc structure could not be captured.
**Autorip**
- Re-inserting a disc after an interrupted rip (crash, power loss, eject) picks up where it left
off instead of restarting from title 1.
- The UI shows how much staging space the selected titles will need before the rip starts, and
a resume no longer fails the space check by ignoring what is already staged.
- Key-service failures get their own messages: an outage, a definitive "no key for this disc",
over quota and unlicensed are told apart, and only the outcomes where retrying can help are
retried. The tracker link in the AACS-failure message is clickable.
_This release aligns all components to 1.7.6._
## Firmware 0.9.2
2026-09-25
`freemkv-firmware` versions independently of the rest of the stack — see the
[Firmware tools](https://freemkv.org/docs/firmware-tools/) reference for the full command ABI.
**Changed**
- **`Feature::Uhd` renamed to `Feature::Unrestricted`.** Same numeric discriminant (`0x03`) — the
wire byte is unchanged, so existing hosts keep interoperating. The new name documents the
intended semantic: one flag now controls all AACS media acceptance — BD, UHD, and the auth-cell
state-band gate below. `Feature::Bd` (`0x04`) is now **deprecated**: `SET`/`GET` still round-trip
through its own NV slot, but it has no runtime effect.
**Added**
- **New lever: the auth-cell state-band widen at `0x00136826`.** Wired through `Unrestricted` on
BU40N 1.00 (`cmp (state>>4),#0xC; bne <6F/02>`), widening the accepted top-nibble set when armed.
`STATE_ON` (`0x01`) widens; `STATE_OFF` (`0x00`) and `STATE_PASSTHROUGH` (`0xFF`) both replay OEM.
A freshly flashed drive with virgin NV boots with `Unrestricted = STATE_ON` — the widen is on by
default.
**Fixed**
- Silent `0x30/0x02 Incompatible medium installed` refusal on a specific triple-layer UHD whose
disc classifier lands its state byte on `0xE8` instead of the usual `0xC*` band that the OEM gate
accepted.
## 1.7.5
2026-09-23
**Fixes**
- **Drives running freemkv firmware 0.9.0 unlock again.** Firmware 0.9.0
consolidates two separate drive controls — one for the authentication
handshake, one for in-transit encryption — into a single control, because the
second one turned out to do nothing on its own. The unlocker now sets the one
control instead of the two that no longer exist. Without this, a drive on
0.9.0 firmware would fall back to the slower online-key route. Drives on older
firmware are unaffected.
**If you flash firmware**
- freemkv-firmware 0.9.0 is a separate release and needs this version of freemkv
to drive it. It fixes a bug where a drive could come up with in-transit
encryption disabled at power-on even when it was configured to leave it on,
and a second one where changing the encryption setting with no disc loaded
would stop the drive answering further freemkv commands until it was
power-cycled. Validated end-to-end on an LG BU40N: a 4K disc returned every
sampled unit unwrapped, and the key resolved normally.
_This release aligns all components to 1.7.5._
## 1.7.4
2026-09-21
**Fixes**
- **Correct main title on BD-J / Java-menu Blu-rays.** Some discs that drive
their menu with BD-J (a Java menu) were having the wrong title picked. 1.7.4
walks the disc's menu, adds a chapter-completeness failsafe, and breaks ties by
stream richness, so autorip and the CLI pick the real main feature — keeping
the Dolby Vision layer and all subtitle tracks instead of a lesser sibling.
- **PGS subtitle "Timestamps are unset" muxing error fixed.** Blu-ray (PGS)
subtitles now carry a proper per-block duration, so muxing no longer fails with
the "Timestamps are unset" error.
- **Clearer "no key in keydb" messaging.** A missing key now tells you whether
the disc simply isn't in the database or is listed but still needs a VID to be
usable, and the lookup now shows the disc hash so a report can be matched up.
**New / Maintenance**
- More resilient keydb downloading: a slow-but-progressing download is no longer
killed by an absolute deadline (rolling-idle timeout).
- Security and quality hardening: OpenSSF Scorecard, REUSE compliance, and
provenance-ready CI across the components.
_This release aligns all components to 1.7.4._
## 1.7.3
2026-09-19
**Fixes**
- **Correct main title on multi-angle / seamless-branch UHD discs.** Some 4K
Blu-rays that use multiple angles for the main feature were having the wrong
title (or no title) picked, because the disc's stream table was read at the
wrong place for a multi-angle playlist. 1.7.3 locates it correctly, so autorip
and the CLI pick the real main feature. Validated against a 92-disc UHD corpus.
**New**
- **`freemkv info … --share` captures a disc's structure for bug reports.** If a
disc still picks the wrong title, `--share` bundles just the small
BDMV/VIDEO_TS metadata (playlists, clip info — a few hundred KB, no video/audio
and no keys) so the problem can be reproduced without sending the whole disc.
Works on a drive, an ISO, or a folder. See
https://freemkv.org/docs/troubleshooting/#sharing-a-profile---share
_This release aligns all components to 1.7.3._
## 1.7.2
2026-09-18
**Fixes**
- **freemkv firmware drives now unlock and decrypt correctly.** Drives running
freemkv firmware were not having all of their features applied during a rip —
in particular, sample data sent for key recovery could still be bus-encrypted,
and some drives fell back to the online/AACS path instead of unlocking
directly. 1.7.2 applies every firmware feature the way it should, so freemkv
firmware drives unlock cleanly and hand off clean, decrypted data.
- **More reliable disc size detection.** Hardened how we read a disc's capacity
so a drive that briefly reports the wrong size no longer produces an empty or
truncated rip.
**New**
- **Use freemkv firmware with 1.7.2.** This release ships the updated firmware
modify support, so drives you flash with freemkv firmware work end-to-end with
the 1.7.2 app.
_This release aligns all components to 1.7.2._
## 1.7.1
2026-09-14
**Fixes**
- **LibreDrive unlocking restored.** A regression in 1.7.0 stopped some drives
from unlocking — those that report a specific model name our catalogue lists
more generically (for example the LG BU40N). 1.7.1 matches them correctly
again, so LibreDrive-based Blu-ray and UHD ripping works on these drives as it
did before.
_This release aligns all components to 1.7.1._
## 1.7.0
2026-09-06
**New — early access (beta)**
- **Renesas drive unlocking.** freemkv can now open selected Renesas / Pioneer
drives for reading, alongside the existing routes. This is early and
unvalidated — if you have one of these drives, give it a try and tell us how
it goes.
- **freemkv firmware.** freemkv can also read drives running freemkv's own
firmware. The companion tools that flash and modify that firmware —
`freemkv-flash` and `freemkv-fw`, each with a command line and a desktop app —
are at [freemkv.org/firmware](https://freemkv.org/firmware/).
**Fixes**
- An MP4/MOV file that uses 64-bit box sizes could be read only part-way
through; it is now walked in full.
- The right drive profile is now chosen for a drive whose exact model isn't in
our catalogue but reports a valid product id — previously it could be matched
to a sibling model, and that model's microcode.
**Security**
- Fixed a low-severity memory-safety issue in the internal sector-prefetch
buffer pool (advisory GHSA-j8ww-f5fg-9pmh). No shipped feature could trigger
it.
_This release aligns all components to 1.7.0._
## 1.6.14
2026-08-31
**Fixes**
- The web dashboard no longer briefly hangs while scanning a large library.
_This release aligns all components to 1.6.14._
## 1.6.13
2026-08-28
**Drive support**
- `freemkv info disc:// --share` now captures a few additional drive
responses on Pioneer / Renesas drives. If you have one of these drives and
would like to help us add support for it, re-run the command and share the
profile it prints.
_This release aligns all components to 1.6.13._
## 1.6.12
2026-08-27
**Ripping**
- **macOS:** fixed a case where the disc could unmount partway through a rip —
seen as `E1000` ("Write failed"), with the disc then re-mounting on its own.
freemkv now holds an exclusive claim on the drive for the whole rip, so the
system no longer takes it back mid-read.
- If the disc or drive state changes underneath a rip, freemkv now reacquires
the drive and restarts the pass instead of failing the read.
_This release aligns all components to 1.6.12._
## 1.6.11
2026-08-26
**Ripping**
- More reliable main-feature detection on Blu-ray and DVD discs: freemkv now
follows the disc's own on-disc navigation to find the main feature, instead
of guessing from title length alone, so it's far less likely to be fooled by
a decoy title.
**Autorip**
- Fixed a rare case where a disc could get stuck endlessly retrying a failed
mux step instead of being marked as failed and moving on.
_This release aligns all components to 1.6.11._
## 1.6.10
2026-08-23
**Ripping**
- Fixed rare Dolby TrueHD / Atmos audio errors on discs that carry a gap in their
transport stream: the ripped track could make some players report audio glitches
around the affected moment, or an integrity checker flag the file as corrupt.
freemkv now resynchronises the audio cleanly across such gaps, so the muxed file
plays back and verifies without the errors. (The gapped instant is in the source
and can't be recovered, but the file is no longer flagged corrupt.)
## 1.6.9
2026-08-22
**Autorip**
- **Automatic per-episode TV ripping** — insert a series disc and every episode comes out as its own `Show S01E02 - Title.mkv`, filed into `TV/Show (Year)/Season NN/`, with no operator step. Episodes are matched to TMDB and numbered correctly even when a season is split across several discs.
- **Manual Rename** — file a disc under any exact name you type, with no TMDB match required, so an alternate cut (e.g. a “Super Duper Cut”) no longer collides with an already-ripped title.
_This release aligns all components to 1.6.9; only autorip changed._
## 1.6.8
2026-08-21
**Autorip**
- Webhooks now fire per pipeline stage — **Rip** (the disc is read and the drive is free), **Mux** (the MKV is produced), and **Move** (the file lands in your library) — each independently selectable per hook
- The **Rip** notification now arrives the moment the drive is free, so you can load the next disc while the mux keeps running in the background — instead of only arriving once the mux had finished
- The Ripper tab's "still working in the background" banner now also shows while a file is being moved, not just while muxing
_This release aligns all components to 1.6.8; only autorip changed._
## 1.6.7
2026-08-21
**Autorip**
- Each webhook can now choose whether it fires on rip complete, move complete, or both
- The Move card shows a separate progress bar for every moved file — the movie and its kept ISO each get their own
- A title that is being moved is no longer listed twice in the Move card
- A failed webhook now logs the real reason (e.g. the connection was reset) instead of a generic "uncategorized error"
_This release aligns all components to 1.6.7; only autorip changed._
## 1.6.6
2026-08-20
**Autorip**
- Webhooks can now point at your LAN (e.g. a Home Assistant automation) — the private-address guard no longer blocks them
_This release aligns all components to 1.6.6; only autorip changed._
## 1.6.5

2026-08-15
**Autorip**
- A stalled upload can no longer restart the service mid-rip
- The main log no longer grows for the life of the container
- A redirected webhook is no longer reported as delivered
**Command line & desktop app**

**Discs & decoding**
- Fixes a Blu-ray/UHD title whose sound ran on about half a minute past the picture

## 1.6.3
2026-08-10
**Command line & desktop app**
- Install with Homebrew on macOS and Linux (`brew install freemkv/tap/freemkv`)
- Asking for forced subtitles in one language no longer ticks several others
- The log can now be shown and hidden while a rip is running
- Hiding the log no longer leaves a blank band across the window (macOS)

- Fixes NTSC DVD chapter marks and durations that ran about 0.1% short
## 1.6.0
2026-08-03
**Command line & desktop app**
- freemkv for Mac — a native desktop app: open a disc or image, tick titles and tracks, press Rip
- One `freemkv` binary is now both the command line and the desktop app
- Pick audio/subtitle tracks by language (`-a` / `-s`)

## 1.5.2
2026-07-22
**Command line**
- The unlock report now labels DVDs as "DVD" instead of "CSS".
**Discs & decoding**
- TrueHD 7.1/Atmos audio is now corrected on AACS-encrypted Blu-ray and UHD discs, instead of falling back to a 5.1 channel count.
- AACS 2.1 menu and extras titles that carry no forensic key now rip using the disc's base key instead of failing.
- Multi-key AACS discs now decrypt each clip with its own key, fixing garbled secondary content.
- CSS DVDs no longer produce garbled output; every read now uses the correct per-title key.
- Scanning a CSS DVD is much faster — about 25 seconds down to about 6.
- A disc that can't be decrypted now stops with an error instead of writing scrambled data or a truncated block out as a broken file.
## 1.5.1
2026-07-20
**Discs & decoding**
- TrueHD audio was being silently dropped entirely (and could send some players into a runaway memory spiral); it is fixed. Titles ripped while this was broken need a re-rip.
- HD DVD AACS keys are now found whatever directory and filename layout the studio used, not just the most common one.
- HD DVD discs with more than one protected title now decrypt all of them instead of just the first.
- A disc with marginal, barely-readable spots no longer "rips clean" while hiding corrupted data; those spots are now retried and either recover or are reported as an honest gap.
## 1.5.0
2026-07-19
**Command line**
- New MP4 output — rip straight to a play-everywhere MP4 with no external transcoder. It's a compatibility export: tracks MP4 can't hold (TrueHD, LPCM, bitmap subtitles) are listed and excluded rather than silently dropped.
- MP4 can now also be used as a source, for a frame-exact round trip into any other format.
- Five new single-part exports: video-only, audio-only, and subtitle-only files, a chapter-markers sidecar, and a full title-structure JSON.
**Discs & decoding**
- Forced subtitles can now be detected from the subtitle content itself, so discs that don't flag them are handled correctly too.
- Corrupt audio frames are now dropped cleanly instead of muxed as glitches, across every audio format, while keeping picture and sound in sync.
- TrueHD: brief bursts of stream damage no longer throw away a whole track or shift the audio that follows.
- Uncommon free-format MP2/MP3 audio is no longer rejected.
## 1.4.5
2026-07-18
**Discs & decoding**
- AACS 2.1 forensic discs now produce a clean stream, instead of visible playback glitches and dropped frames around each forensic segment.
- A decryption key written with an uppercase prefix is no longer silently ignored.
**Security**
- Decryption keys can no longer end up in a log or crash message.
## 1.4.4
2026-07-17
**Discs & decoding**
- Online key lookups were sometimes skipped before ever reaching the key service; they now run reliably.
## 1.4.3
2026-07-17
**Discs & decoding**
- The online key service can now return a full forensic key set as well as a single key.
## 1.4.2
2026-07-15
**Discs & decoding**
- Fixed a bug where content that decrypted fine but didn't parse as clean video could blank out good picture and repeatedly re-query the key server for a key it already had.
## 1.4.1
2026-07-14
**Discs & decoding**
- A single bad packet no longer causes a whole block of good video to be discarded.
- A track is now flagged 3D only when that information is actually present on the disc.
## 1.4.0
2026-07-13
**Discs & decoding**
- Blu-ray 3D (MVC) support — a 3D disc rips to a single MKV that preserves both eyes, with no transcoding or side-by-side conversion. The 2D view is byte-identical to a standard 2D rip.
## 1.3.2
2026-07-10
**Discs & decoding**
- Better recognition of AACS 2.1 forensic-variant discs, ahead of full decryption support.
## 1.3.1
2026-07-10
**Discs & decoding**
- HD-DVD titles now use the disc's own playlist for clip order, duration, name, and chapters instead of guessing from filenames, with the old guess kept as a fallback.
**Project**
- Relicensed to the MIT License from 1.3.1 onward (releases through 1.3.0 remain AGPL-3.0).
## 1.3.0
2026-07-08
**Discs & decoding**
- AACS 2.1 (FMTS) discs are now recognized as their own format and mostly rip, with only the not-yet-supported forensic segments skipped.
- Initial HD-DVD support — HD-DVD is detected as its own format and its video and audio rip through the pipeline. Title composition is still a best guess, so a disc that authors two features under one naming scheme may show as a single title.
- Older program-stream video (H.264, VC-1, HEVC on HD-DVD and older discs) now gets correct per-frame timestamps.
- The main feature is now picked by physical size, so a disc that splits its feature across many small clips is no longer passed over for a shorter composite.
- More reliable track-label detection across differing disc authoring, with a last-resort fallback that reads menu-artwork languages.
**Security**
- Disc metadata (title, labels) is now cleaned before it's printed, so a malicious disc can't inject terminal control sequences.
## 1.2.2
2026-07-04
**Discs & decoding**
- AACS 2.1 Media Key Variant support now matches real variant discs.
- Fixed AACS device-key fallback that had been silently broken.
- Resolving the AACS processing key on UHD discs is roughly 15× faster — about 37 seconds down to about 2.4.
## 1.2.1
2026-07-02
**Discs & decoding**
- DVD DTS audio no longer muxes with timestamps that some strict players rejected.
## 1.2.0
2026-07-01
**Command line**
- Progress now includes a per-range breakdown of damage — chapter, movie-time offset, and at-risk time.
- A rip now reports which unlock mechanisms (firmware, AACS, CSS) actually ran.
**Discs & decoding**
- Damaged-disc recovery now tries a wider set of techniques, re-ranked per disc by what's actually working.
- Added an optional recovery mode for discs with heavily hardened damage.
- A new "fast capture" pass grabs every readable block first, before falling back to slower per-sector recovery.
- A block that genuinely can't be decrypted is now concealed cleanly so the file still plays, instead of writing broken data.
- Recovery can no longer hang forever on a wedged drive.
- Every DVD now rips at full speed — a drive speed-up had been skipped for DVDs.
- DVD DTS/LPCM tracks that weren't the disc's first audio no longer come out silent.
- Real video is no longer dropped at the end of an encrypted fragment.
- Audio no longer corrupts across a stream discontinuity.
- Online key lookups for disc images now send the required data, instead of every request being rejected.
- Discs using an older AACS version now read their keys correctly.
- Fixed a possible crash on a corrupt disc.
## 1.1.0
2026-06-28
**Command line**
- Every user-facing error now shows an error code, with a new Error Codes reference page listing the cause and next steps for each, in all supported languages.
- Windows-reserved filenames on a disc are now safely renamed on extraction instead of aborting.
**Discs & decoding**
- Every decrypted unit is now verified before it's accepted, catching a class of silent bad read.
- Stricter AACS acceptance, so a wrong key can't coincidentally pass and quietly corrupt output.
- DVD rips now start on the actual movie instead of the disc's menu screens.
- Multi-part files in folder extraction no longer have later parts written as empty holes.
- Fixed a rare false frame-split in DTS-HD Master Audio.
- Fixed TrueHD timestamps stepping backward under certain source timing.
- Fixed several container-metadata issues (color info, subtitle wipe, sidecar alignment).
**Security**
- Fixed a misread flag that could defeat a safety check meant to refuse decrypting encrypted-bus content with no bus key.
## 1.0.0
2026-06-24
First stable release.
- A command-line tool that rips optical discs to MKV.
