• Add SNTP as a dependency for GCP
• mos: Do not generate init code for libs with no sources
• Remove mongoose.{c,h} from the mongoose-os repo; mongoose library should be used instead.

mos tool:

• The mos tool is factored out from the mongoose-os repo to a separate repo https://github.com/cesanta/mos-tool, see its release notes there: https://github.com/cesanta/mos-tool/releases/tag/1.26

Mongoose OS:

• Add GPIO open-drain output mode
• Rewrite bitbang I2C to use open-drain output, make frequency adjustable
• CC3200: Fix OTA regression, which caused OTA to fail
• CC3220: Update SDK to 1.60.00.04

• Do not put sys config schema defs on the device FS by default
• Add a simple heap-backed VFS device, mostly for testing

Mos tool:

• Default location for all modules, including mongoose-os, is now "deps", so one could place under deps all libs, mongoose-os (and maybe mjs_module), and have a hermetic reproducible build.
• Do shallow clone for the mongoose-os repo

Mos tool:

• Fix brew build: mos shouldn't check for updates because when installed via brew it should be updated also via brew

Firmware:

• BREAKING: SNTP is now factored out to a separate library, so apps should include it explicitly if that functionality is needed.
• Implemented mgos_event_add_group_handler() in C and Event.addGroupHandler() in mJS
• BREAKING: mgos_net_add_event_handler() is deprecated in favor of mgos_event-based API. See comment for MGOS_EVENT_GRP_NET for the example.
• Increased CC32xx UART buffer size
• Many improvements in dashboard support (and in the dashboard itself)
• Added DigiCert root

Fix brew build: mos shouldn't check for updates because when installed via brew it should be updated also via brew

Mos tool:

• Fix aws thing name for the cases when it's not the default <arch>_<mac>

Firmware:

• BT: Add API for managing pairing; improve security
• ESP32: update ESP-IDF
• ota-aws-shadow library improved and renamed to ota-shadow
• Add events API, see mgos_event.h
• Add wifi.ap.hostname: e.g. if it's set to foo.com, then all clients connected to the device's wifi AP would be able to use the hostname foo.com instead of the device's IP 192.168.4.1.

This is a bugfix release.

• Fetching prebuilt apps during initial setup was failing;
• For local builds, --libs-dir didn't work correctly for libs which aren't git repositories.
