Version 4.2
-----------

Release Date: 2026-07-10

* add support for Python 3.14 (and thus Ubuntu 26.04). We now use the Python EzSnmp v2.3 library (from v1.1)
* add ability to disable reading of hardware info per device or per group from the admin pages, or globally via a *settings.py* variable.
  Disabling this can save significant time on older, slower devices and switch stacks.

Bug fixes:

* fix vlan change regression bug in several SNMP drivers.
* fix port to ifindex map regression bug in Cisco SNMP driver.
* fix allowed vlan parsing error in Arista eAPI driver.
* interface and ethernet spreadsheet download optimization.
* handle poe change, vlan change, and tags editing in the "standard" way in the actions.py classes.
* protect vlan actions for invalid http methods
* detect invalid data types in snmp set.
* update consistent naming of snmp _parse_mibs_functions()
* many pylint updates.
