This update will cover all the major activity since [SOTF #5](/blog/2022/04/10/zmk-sotf-5). That was over a year ago (again!), so lots to cover! ## Recent Activity Here's a summary of the various major changes since last time, broken down by theme: ### Keymaps/Behaviors Global quick tap [#1187] Key toggle [#1278] Mask triggering modifiers by default in mod morphs and add `keep-mods` property [#1412] Fix bug causing stuck keys with combo & hold-tap interactions [#1411] Add `hold-trigger-on-release` property for positional hold-tap uses [#1423] Sticky key fixes [#1586], [#1745] Parameterized macros [#1232] Add sensor rotate behaviors to use invoke any behavior from encoders [#1758] Caps word ignore modifiers [#1330] ? Tap dances can be used in combos [#1518] ? ### Bluetooth and Split Improvements Release held keys on peripheral disconnect [#1340] Connections status check fix [#1810] Option to require passkey input on pairing [#1822] Multiple peripherals support [#836] Improve `settings_reset` shield by making it clear bonds more reliably, and allow it to build for all boards [#1879] Use directed advertising for split communication and more robust central scanning [#1913] [#1912] ### Hardware Support Encoder support refactor [#1039] Encoder support in split peripheral halves [#728] [#1841] Debouncing for direct GPIO driver [#1288] Add toggle mode support for direct GPIO driver [#1305] 595 shift register driver [#1325] Add RGB auto off options using idle timeout and USB status [#1010] EPD initialization improvements [#1098] MAX7318 GPIO expander driver [#1295] nice!view support [#1462] with custom status screen [#1768] Improvements for Seeeduino Xiao BLE [#1293], [d0176f36], [#1545], [#1927] Wait options during matrix reads and writes [#1385], [#1473] ? ### Miscellaneous Improved customer page support [#1227] Switch to a reusable user config workflow [#1183] [#1258] Pre-commit setup and standardize formatting [#1651] Refactors by Joel [#1269] [#1255] ? Allow setting BLE connection intervals [#862] ? Default to 1ms USB HID interval [#1271] ? Allow configuring battery level report interval [#1303] ? #### Display Features Add setting to invert display colors [#1754] Add battery percentage option for battery widget [#1563] ? Refactor to create new peripheral status widget [#1263] ? #### Zephyr 3.2 [petejohanson] helped prepare and test the upgrade of ZMK to Zephyr 3.2 in [#1499](https://github.com/zmkfirmware/zmk/pull/1499). ### Documentation Configuration options [#722] Battery sensor documentation [#868] New behavior guide [#1268] Tap dance and hold-tap documentation improvements [#1298] New shield docs for other interconnects including Xiao, Arduino Uno and Blackpill [#1607] A new Bluetooth feature page [#1499] Various improvements and fixes by kurtis-lew, joelspadin, filterpaper, byran.tech, dxmh, caksoylar and many others ## New Shields - Eternal keypad [#1136] - nullbits SNAP [#1319] - Aurora Sweep [#1504] - Aurora Corne [#1520] - Aurora Lily58 [#1553] - Aurora Sofle [#1864] - Aurora Helix [#1873] - ZMK Uno shield [#1576] - Waterfowl [#1554] - Kyria Rev 3 [#1627] - Leeloo v2 and Leeloo-Micro [#1762] - Spaceman Pancake [#1400] - Reviung5 [#1548] ## New Boards - RP2040 boards - Puchi BLE [#1445] - nRFMicro 1.3/1.4 (nRF52833) [#912] - nRF5340 DK [#1562] - PillBug [#1530] - Preonic Rev 3 [#1575] - Corne-ish Zen v2 [#1498] and v1 [#1593] - Polarity Works CKP family of boards [#1547] ## Coming Soon! Some items listed in the last coming soon section are still under active development. - Caps/Scroll/Num Lock LED support - Mouse Keys - Wired split support - More modular approach to external boards/shields, custom code, user keymaps, etc. - More shields and boards ## Statistics Some statistics of interest for ZMK: - GitHub (lifetime stats) - 163 Contributors - 1239 Closed PRs - 1845 Stars - 1918 Forks - Discord Chat - 7865 total registered (130% up from last SOTF!) - Website (last 30 days) - 35.9K page views - 3.29K new users ## Sponsorship [Open Collective](https://opencollective.com/zmkfirmware) [Pete Johanson](https://github.com/sponsors/petejohanson) (detail what is used for what) ## Thanks! As we approach the two year birthday for ZMK, I am reminded of how far we have come in such a short time, in large part thanks to the _amazing_ community that has grown around it. I am so grateful to have so many contributors, testers, and user believing in the project and helping make it a joy to work on.
