I'm sending notice that the 1.6 release line will reach End-Of-Life by Thursday 10 June - next month. As per our community policy, there will be no further fixes applied to the 1.6 series of releases. After its initial release on June 10, 2018 and 31 patch releases - the latest released just 5 days ago on May 2 - the 1.6 release line will have received 3 years of support.
Note that even though the community won't provide further releases, the software is considered highly stable and will keep working as it has. This End-Of-Life announcement has no impact on migration paths to newer versions of LedgerSMB: upgrades from 1.6 to more recent versions will remain supported for many years to come. (Upgrade paths from LedgerSMB 1.2 and 1.3 have seen recent maintenance.)
Should you want to keep running 1.6 and be in need of support or maintenance, you could try contacting one of the parties listed on the page for commercial support: https://ledgersmb.org/content/commercial-support. They may be able to provide support beyond the community commitment.
Available options for versions with community support are the 1.7 release line which will receive community releases until October 04, 2022 or the 1.8 release line which will see community support until September 04, 2022. (For releases 1.8 and newer, only 2 years of community support have been committed due to the increased release frequency: new minor versions are now released on a yearly basis.) For community support until 2023, upgrading to 1.9 is advised, which is expected to be released later this summer.
