5.1

Changelog:

• ThroughSerial strategy able to leverage of the Software and Hardware Serial port (https://github.com/gioblu/PJON/tree/5.1/strategies/ThroughSerial)
• Added RS485 tx enable pin handling in ThroughSerial (71e59a0)
• receive function optimization (fd97d23)
• Header driven sending, not configuration driven (6a8cdf9)
• Extended documentation in .md files rather than in wiki

Bugfix:

• Cubic backoff bugfix (eef9592)

5.0

PJON Protocol layer specification released v0.1 - v0.2 - v0.3
Padded jittering data link layer specification released v0.1

Changelog:

• Complete data link layer abstraction. Now a strategy includes configuration and communication pin setter, i.e. bus.strategy.set_pin(12) and the send_string method to ease other strategies creation or extension (why not an Ethernet strategy?).
• Packet sending optimization. From PJON v5.0 the packet is composed, and its CRC calculated, once, when dispatched. The PJON_Packet buffer has been simplified and the packet's additional info saved in the content attribute with the information.
• Documentation in readme to handle more efficiently versioning and avoid duplication
• Dropped pow substituted by value * value because of its memory footprint
• Definitions moved in PJONDefines.h
• Because of a more optimized execution timing the necessity of a pull-down resistor for OverSampling and SoftwareBitBang strategy is reduced, and in many cases also a complex bus can run without it
• Methods in alphabetic order

4.3

Changelog:

• pre-allocated buffers to reduce memory usage, avoid fragmentation and finally drop malloc().
  With this change, the default PJON codebase will need more memory than the previous releases, but can be tuned to fit the requirements. To reduce the memory consumption simply pre-define MAX_PACKETS and PACKET_MAX_LENGTH constants to fit your needs before PJON.h inclusion. For example if your device transmits up to one packet, you can limit MAX_PACKETS to 1.

Bugfix:

• info_overhead function definition bugfix
• acquire_id experimental functionality removed

4.2

Changelog;

• get_packets_count added to count active packets (dc62a7e) by @pantonvich

Bugfix:

• can_start bugfix in ThroughHardwareSerial (1c8b71a) by DanRoad reddit user
• Useless flush special case removed in ThroughHardwareSerial (72cbfde)

• Wrong length in receiver function bugfix (1b594d2) by @fredilarsen
• Fix path to examples in platformio manifest file @ivankravets

4.1

Changelog:

• Physical layer strategy now public, switch to strategy.method call reducing memory consumption by circa 5%, enabled strategy.method call from sketch (see set_serial in ThroughHardwareSerial)
• ThroughHardwareSerial Strategy added to enable PJON communication over Serial
• Added ThroughHardwareSerial examples

Bugfix:

• b_id bug fixed (fe6936f)
