cr_works() gain ability to show a progress bar when using
deep pagination when using works=TRUE (#186) (#188)cr_works() returned a tibble in the $data
slot in each case except for when a single DOI was passed to the
doi parameter. now fixed (#184) thanks @martinjhnhadleycr_works(),
cr_works_(), and cr_citation_count(). See the
new parameter async (logical) in those functions. For
cr_citation_count(), it now accepts more than 1 DOI, and
the output has changed from a numeric value to a data.frame (columns:
doi and count). With async=TRUE
for cr_works() you get a list of data.frame’s; while for
cr_works_() you get a list of JSON’s (#121) (#160)

(#180) thanks @nicholasmfraser for the bug

bad/invalid/malformed DOI, throw warning and give back an
NA (#164) thanks for the report @chremancr_cn()
(#168)cr_cn() when bibentry not valid,
that is not parseable. before the package we use to parse
bibtex would stop on invalid bibentry data, but now we get
around the invalid bits and give back the bibentry (#147)dois parameter (#162)
thanks @ms609cr_* functions. We now
give errors like
404 (client error): /works/blblbl - Resource not found.,
which includes HTTP status code, major class of error (success,
redirect, client, server), the route requested, and the error message
(#163)cr_works() in which field queries should
have been possible for title and affiliation, but were not. Fixed now.
(#149)cr_journals() was not correctly parsing data when more
than 1 ISSN given and works set to TRUE, fixed
now (#156)cr_journals() was not correctly parsing data when no
ISSN found and works set to TRUE, fixed now
(#150)cr_journals() was not correctly handling queries with
multiple ISSN’s and works set to FALSE, fixed
now (#151)cr_works(), and any other
cr_* function that set works=TRUE. the
license slot can have more than 1 result, and we were only
giving the first back. fixed the parsing on this to give back all
license results (#170)/works route gain a
select parameter to select certain fields to return
(#146)sort
parameter (#142)flq parameter) (#143)publisher-name). You can see the filters with the functions
filter_details/filter_names. Beware, some
filters error sometimes with the Crossref API - they may not work, but
they may, let me know at https://github.com/ropensci/rcrossref/issues or let
Crossref know at https://github.com/CrossRef/rest-api-doc/issues (#136)

- previously only allowed a boolean) (#129)cr_funders and cr_journals to give
back facet data along with other data (#134)cr_* functions to check for a missing

(#124)cr_search and cr_search_free are now
defunct. They were marked deprecated in previous version, and warned of
defunct, and now they are defunct. Similar functionality can be done
with e.g., cr_works() (#102)crosscite is now defunct. The functionality of this
function can be achieved with cr_cn() (#82)cr_fundref is now defunct. Crossref changed their name
fundref to funders, so we’ve changed our
function, see cr_funders() (#83)sample maximum value is now 100, was
previously 1000. documentation updated. (#118)has-clinical-trial-number and
has-abstract added to the package, see
?filters for help (#120)?rcrossref for more. Addin authored by Hao Zhu @haozhu233 (#114)cr_abstract() that tries to get an
abstract via XML provided by Crossref - NOTE: an abstract is rarely
available though (#116)cr_cn() where DOIs with no minting agency
found were failing because we were previously stopping when no agency
found. Now, we just assume Crossref and move on from there. (#117)
thanks @dfalster
!cr_r() when number requested > 100. Actual
fix is in cr_works(). Max for sample used to be 1000, asked
this on the Crossref API forum, see https://github.com/CrossRef/rest-api-doc/issues/146

Crossref web services, so are now marked deprecated, and will throw a
deprecation message, but can still be used. They will both be defunct in

content manually. in addition, encoding explicitly set to

some failed requests (#97) thanks @nkorfcr_fundref()/cr_funders() - parsing wasn’t
working correctly in all casesSkipped v0.4 to v0.5 because of many
changes - as described below.
cursor, which
accepts a cursor alphanumeric string or the special *,
which indicates that you want to initiate deep paging;
cursor_max, which is not in the Crossref API, but just used
here in this package to indicate where to stop - otherwise, you’d get
all results, even if there was 70 million, for example. A new internal
R6 class used to make cursor requests easy (#77)id_converter() to get a PMID from a DOI
and vice versa (#49)cr_types(), along with its low level
equivalent cr_types_() for when you just want a list or
json back (#92)cr_funders_(), cr_journals_(),
cr_licenses_(), cr_members_(),
cr_prefixes_(), cr_types_(),
cr_works_(). These functions are a bit faster, and aren’t
subject to parsing errors in the event of a change in the Crossref API.

(thanks @njahn82).progress parameter use internally where it
wasn’t applicable.sample parameter dropped from
cr_licenses().cr_works() parsing changed. We now don’t attempt to
flatten nested arrays, but instead give them back as data.frame’s nested
within the main data.frame. For example, author often has
many entries, so we return that as a single column, but indexing to that
column gives back a data.frame with a row for each author, and N number
of columns. Hopefully this doesn’t break too much code downstream
