Published June 22, 2022

Fixes:

• (#2451) Removes accidental duplicate 0x prefix for printed EVM addresses

Published June 21, 2022

Features:

• (#2374, #2415, #2416) Replaces legacy Ethereum signing pathway with a new EVM decoder in the general signing framework.

• Adds ability to scroll between used addresses on the Lattice UI. Currently only BTC addresses, which have a gap limit, can display more than the root address but more may be added later.

Bug Fixes:

• Add timeout mechanism to PIN screen, which previously blocked transition to the UI sleeping after inactivity.
• Skip wifi setup step when the Lattice system is reset and the user still has wifi configured.
• Fixes invalid callback handling which made canceling a seed restore entry more difficult than it needed to be.

Changelog:

• Support for derivation paths <5 indices (#1974)
• Modularize vendor libs and optimize compilation (#1975)
• Move RLP module to GridPlus handle and swap submodules (#1976)
• Update address display mechanism to allow scrolling between cached addresses (#1954)

v0.10.4

Published March 31 2021

Features:

• Updates signTransaction request to allow for requests larger than one frame. Previous limit was 1550 bytes for data (same limit for a personal_sign. message). This has now been updated to 1550 bytes + 1x 1500 byte frame for a total of 3050 bytes. (#1945, #1948)
• Updates the look of the PIN screen, most notably using a larger font for the number buttons. (#1946)
• Adds BIP32 signer path to transaction request screen (#1971)

Bug Fixes:

• Blocks requests while ABI confirmation screen is drawn. This fixes a bug in which encrypted requests could still be made but could not be filled because the ABI confirmation screen was blocking the UI. (#1947)
• Forces SafeCard unlock before accessing a cached request when the device is unlocked. This fixes a bug that allowed the device to sign a transaction from a SafeCard without requiring the user to unlock that SafeCard first. This bug was only relevant for locked devices with cached requests. (#1949)

Changelog:

• #1945: Updates signTransaction route and all ETH transaction middleware to handle chained requests, effectively increasing the maximum transaction size by using multiple requests.
• #1948: Increases extraData frame size and stack size to support a significantly larger signTransaction payload under the new mechanism.
• #1947: Adds hook into ABI commit screen preventing inbound encrypted requests while the screen is drawn.
• #1949: Adds more context to system unlock and adds specificity over home_ui redirect when tearing down loading screen.

• #1950: Bump to version 0.10.4
• #1955: Minor code cleanup to adjust comments and remove dead code
• #1957: Adds missing cache clearing mechanism which should have been included in #1948
• #1964: Fixes timeout mechanism when resetting router
• #1971: Prints BIP32 signer path on ETH and ETH_MSG signing request screens

v0.10.3

Published March 17 2021

Features:

• Better detection of the SafeCard. If a SafeCard is inserted when the device boots, it is now detected. If a SafeCard is inserted in a device that is unlocked, the SafeCard now also needs to be unlocked.
• Various UI improvements such as a new cancel button added to the pairing secret screen.
• Optional BIP39 password (a.k.a. "25th word") is now allowed when a wallet is generated.
• ABI updates: ABI_V2 (released in mainnet Dec '20) now supported and tuple types (increasingly utilized by more modern smart contracts) are also now supported.
• Uniswap router V2 ABI definitions now pre-loaded.

Bug fixes:

• Invalid characters (non-ASCII) now represented with a single square character (🔲)). Previously these characters were either skipped or shown as screen artifacts.
• Cleanup of invalid strncat usage in various places.

v0.10.2

Published Jan 20 2021

This release contains a fix to prevent random tamper events in the field related to an overly sensitive tamper mesh.

Changelog:

• #1870: Revision to tamper mesh config to prevent invalid triggering in v2 hardware revs.

v0.10.1

Published Jan 13 2021

This release includes a fix relative to v0.10.0.

Changelog:

• #1860: Adds missing call to clear staged ABI definitions at ABI filesystem init. This functionally means that users had to approve preloaded definitions before, but no longer need to.

v0.10.0

Published Jan 12 2021

This is a minor release which contains features, minor UI tweaks, and bug fixes.

Larger Features:

• Human readable Ethereum transactions via smart contract ABI definition loading and parsing
• Permissions v0: time and spending limits on simple ETH and BTC transfers

Changelog:

• #1738: Cleans up various build configs.
• #1739: Removes the staging config added previously based on our observation that it would not be useful.
• #1740: Fix associated build flags in some unit tests in light of the changes to the DEBUG compile flag.
• #1741: Fix typo in CMakeLists.txt.
• #1749: lvgl #define renames
• #1751: Update lvgl submodule
• #1754: System hook to subscribe to card manager events
• #1759: Reset sleep timer on card insertion/removal
• #1764: Import cb0r lib
• #1772: Add cbor print util
• #1781: Add bignum printing to cbor print util
• #1787: Allows for display of larger Ethereum value amounts -- this supports display of values up to UINT256_MAX
• #1813: Permissions v0
• #1817: Wake device on signing request
• #1821: Compile flag for clone card feature
• #1822: Compile flag for update manager
• #1823: Language update to tamper screen
• #1824: Ethereum transaction data markdown using ABIs
• #1825: Compile flag for permissions v0

• #1839: Blocks permissioned auto-signing of Ethereum transactions with non-zero data payloads
• #1842: Fix bug in system_card_insertion_hook
• #1843: Fix bug in permissions that was preventing permissioned requesters from making ETH_MSG requests
• #1846: Comment out erroneous screen drawing function for the time being. Will be fixed at a later time.
• #1849: Updates Ethereum ABI parser module to handle edge case
• #1850: Updates Ethereum ABI parser module once more to remove erroneous sanity check from previous commit

v0.9.8

Published Dec 4 2020

• #1763: Add option to display extraText left-justified (defaults to the legacy center alignment) and also fixes bug in calculating the size of the pages when line breaks are introduced.
• #1770: Allows our Ethereum transaction parser to parse large chainID values, which were previously encoded as uint8_ts. Sidechains, testnets, and various other networks will use larger values for the chainID, which this PR enables.
• #1775: Fixes race condition in wallet_task that occurs during the card cloning process
• #1783: Fixes a nasty bug where the device times out and blanks the screen while the user is writing down their seed phrase. We should have had a block on that screen, which has been added in this PR.
• #1786: Adds more visual cues to the different lock screens (card vs system) to give users more clarity. We have had a few confused users who haven't been able to differentiate between the screens.
• #1795: Displays GCE SSH login credentials on the device info screen, even for production devices. Almost all of our user bugs/issues have arisen on the GCE side and not being able to debug those could lead to massive support issues. We have thus elected to display the information a user needs to SSH into the device on the device info screen. This also has the benefit of enticing developers to "hack" around with their device.
• #1796: Various language updates throughout the UI.
• #1798: Fixes bug introduced by me in #1795 🙈
• #1799: More language updates to the UI
• #1800: Fixes an oversight from #1770. We were not skipping over the chainID in the data field in the transaction display screen and this PR fixes that.

v0.9.6

Published Sep 30 2020

• Our first version 🎉
• Core Lattice firmware functionality
