65

This is the first beta of the 2.5 series, leading up to a 2.5.0

66

release in February 2012. Beta releases are suitable for everyday use

67

but may cause some incompatibilities with plugins. Some plugins may need

68

small updates to work with 2.5b1.

107

* Add a config option gpg_signing_key for setting which GPG key should

58

be used to sign commits. Also default to using the gpg user identity

59

which matches user_email() as set by whoami. (Jonathan Riddell,

which matches user_email() as set by whoami.

(Jonathan Riddell, #68501)

61

111

62

112

* An ``invalid`` parameter can be specified when registering a config option

63

113

to decide what should be done when invalid values are

64

encountered. 'warning' and 'eeror' will respectively emit a warning and

114

encountered. 'warning' and 'error' will respectively emit a warning and

65

115

ignore the value or errors out. (Vincent Ladeuil)

66

116

117

* bzr add now skips large files in recursive mode. The default "large"

118

size is 20MB, and is configurable via the add.maximum_file_size

119

option. A value of 0 disables skipping. Named items passed to add are

120

never skipped. (Shannon Weyrick, #54624)

121

67

122

* ``bzr help configuration/<option>`` display the help for ``option`` for

68

123

all registered configuration options. (Vincent Ladeuil, #747050)

69

124

70

* bzr log -m now matches message, author, committer and bugs instead

71

of just matching the message. --message keeps its original meaning,

72

while --match-message, --match-author, --match-committer and

73

--match-bugs match each of those fields.

125

* ``bzr log -m`` now matches message, author, committer and bugs instead

126

of just matching the message. ``--message`` keeps its original meaning,

74

130

* ``config.Option`` can now declare ``default_from_env``, a list of

76

131

environment variables to get a default value from. (Vincent Ladeuil)

85

140

* Relative local paths can now be specified in URL syntax by using the

86

141

"file:" prefix. (Jelmer Vernooij)

87

142

88

* Report commits signed with expired keys in "verify-signatures".

* ``bzr commit`` now correctly reports missing files as "removed", not

151

195

"modified". (Jelmer Vernooij, #553955)

152

196

154

198

in a single invocation, e.g. ``--branch`` and ``--use-shared``.

(Martin von Gagern, #842993)

159

branch on the same host as the source branch.

160

(Martin von Gagern, #483661)

201

* A call to CHKInventory's filter-method will not result in a

DuplicateFileId error, if you move a subfolder and change a file in

203

that subfolder.

raised whenever a transport at the drive root was opened on windows.

* Fixed loading of external merge tools from config to properly decode

220

command-lines which contain embedded quotes. (Gordon Tyler, #828803)

180

222

* Rather than an error being raised, a warning is now printed when the

181

223

current user does not have permission to read a configuration file.

229

(Martin von Gagern, #483661)

230

184

231

* TreeTransformBase.fixup_new_roots no longer forces trees to have a root, so

185

232

operations that use it, like merge, can now create trees without a root.

value in SI format (i.e. "20MB", "1GB") into its integer equivalent.

258

(Shannon Weyrick)

259

260

* New method ``InterTree.file_content_matches`` which checks that

261

two files in different trees have the same contents.

262

(Jelmer Vernooij)

263

264

* New method ``Tree.get_file_verifier`` which allows tree implementations

to return non-sha1 checksums to verify files.

unlike ``get_transport``. (Jelmer Vernooij)

tags and whether tags can refer to ghost tags.

* ``Tags.merge_to`` now returns a dictionary with the updated tags

304

and a set of conflicts, rather than just conflicts. (Jelmer Vernooij)

305

256

306

* There is a new class `ContentFilterTree` that provides a facade for

257

307

content filtering. The `filtered` parameter to `export` is deprecated

258

308

in favor of passing a filtered tree, and the specific exporter plugins

no longer support it.
