Changes since 2.4.45:
(this list includes changes from 2.5.x)

New dependencies (automatically installed when using pip):

• pyasn1_modules 0.1.5+

Python 3 support and bytes_mode:

• merged from the pyldap fork (https://github.com/pyldap)
• please see documentation on bytes_mode and text/bytes handling:
  https://python-ldap.readthedocs.io/en/latest/bytes_mode.html

Removed support for Python 2.6.

Infrastructure:

• Move to Git
• Don't define search path for includes and libs in the default setup.cfg
• Include sasl/sasl.h from the standard path
• Re-format README to ReStructured Text
• Setup for automatic testing using Travis CI
• Add coverage reporting for Python and C
• Add install requires into setup.py
• Remove distclean.sh in favor of make clean
• Use package, depends, install_requires in setup.py
• Add make target for scan-build (static analysis using clang)
• Add make target and suppression file for Valgrind (memory checker)

Modules/

• Remove unused LDAPberval helper functions
• Fix type conversion in page control
• Fix multiple ref leaks in error-handling code
• Fix reference leak in result4
• Fix several compiler warnings
• Fix memory leak in whoami
• Fix internal error handling of LDAPControl_to_List()
• Fix two memory leaks and release GIL in encode_assertion_control
• Allow set_option() to set timeouts to infinity
  and, thanks to Michael Ströder:
• removed unused code schema.c
• moved code from version.c to ldapmodule.c
• removed obsolete back-ward compability constants from common.h
• build checks whether LDAP_API_VERSION is OpenLDAP 2.4.x
• _ldap.author and _ldap.license also set from ldap.pkginfo
• assume C extension API for Python 2.7+

Lib/

• Avoid eval() for getting module-level variables to fix running under pytest
• Compability changes for pyasn1 0.3 or newer
  and, thanks to Michael Ströder:
• ldap.version, ldap.author and ldap.license now
  imported from new sub-module ldap.pkginfo also to setup.py
• Added safety assertion when importing _ldap:
  ldap.pkginfo.version must match _ldap.version
• removed stand-alone module dsml
• slapdtest.SlapdObject.restart() just restarts slapd
  without cleaning any data
• The methods SSSResponseControl.decodeControlValue() and
  VLVResponseControl.decodeControlValue() now follow the coding
  convention to use camel-cased ASN.1 name as class attribute name.
  The old class names are still set for back-ward compability
  but should not be used in new code because they might be removed
  in a later release.
• removed SSSRequestControl from ldap.controls.KNOWN_RESPONSE_CONTROLS
• removed all dependencies on modules string and types
• removed use of .has_key()
• removed class ldap.ldapobject.NonblockingLDAPObject
• new global constant ldap.LIBLDAP_API_INFO
• right after importing _ldap there is a call into libldap to initialize it
• method .decodeControlValue() of SSSResponseControl and VLVResponseControl
  does not set class attribute result_code anymore
• always use bytes() for UUID() constructor in ldap.syncrepl
• module ldif now uses functions b64encode() and b64decode()
• fixed pickling and restoring of ReconnectLDAPObject

Lib/slapdtest

• Automatically try some common locations for SCHEMADIR
• Ensure server is stopped when the process exits
• Check for LDAP schema and slapd binaries
• slapdtest is now a package and includes testing certificates

Tests/

• Expand cidict membership test
• Add test suite for binds
• Add test suite for edits
• Add a smoke-check for listall() and attribute_types()
• Add test case for SASL EXTERNAL auth

  and, thanks to Michael Ströder:
• added explicit reconnect tests for ReconnectLDAPObject
• scripts do not directly call SlapdTestCase.setUpClass() anymore
• added LDIF test with folded, base64-encoded attribute
• added more tests for sub-module ldap.dn

Doc/

• Build documentation without the compiled C extension
• Merge contents from python-ldap.org
• Move reference documentation in its own section
• Document return value of {modify,add,delete}_ext_s() as a tuple
• Add tests for documentation (build & spelling)

• Add a contributing guide
