*************************

Bazaar 2.7 has been released on the 1st of February 2016 and marks the start

Users are encouraged to upgrade from the other stable series. This document
15
outlines the improvements in Bazaar 2.7 vs Bazaar 2.6. As well as
16
summarizing improvements made to the core product, it highlights

Bazaar 2.7.0 is fully compatible both locally and on the network with 2.0,
21
2.1, 2.2, 2.3, 2.4, 2.5 and 2.6, and can read and write repositories
22
generated by all previous versions.
27
python 2.6 has been EOL'ed since the release of bzr 2.6. The last python 2.6
28
version was released on 2013-10-29. While bzr 2.7 remains compatible with

python 2.6, no further update of bzr is expected in this regard.

SSL Certificate Verification Support in urllib HTTPS backend
32
************************************************************
34
python 2.7 received security updates regarding SSL certificate
35
verification. bzr 2.7 relies on the ssl python module for this and as such
36
benefit from these security updates.
38
This isn't true for python 2.6 so users are encouraged to upgrade.
40
Users that cannot upgrade will be warned that the hostname cannot be
41
verified and can remove the warnings by setting the ``ssl.cert_reqs`` option
47
Most of the bug fixes in 2.7 are related to test failures triggered by
48
various python 2.7 updates. Among other distributions, debian and ubuntu
49
have carried patches that have now part of bzr 2.7.
